Date Reviewed: August 16, 2007
Favorite Trail:Kirroughtree
Duration Product Used:2 Years
Price Paid: $1000.00
Purchased At:Came with bike
Strengths:When working works very nicely, plush, stiff and terralogic fantastic uphills.
Weaknesses:The Seals are complete sh1t. I have managed only 15 rides between each set of seals. The importers to the UK charge £90 for servicing which is approx $180. Yup, every 3 months. And that is for dry riding too - I daren't introduce them to mud! So now I ride my road bike unless there is something very special and dry to go off road for.

Anodising began wearing off after approx 30 (dry) rides.

Customer service - if you fancy being insulted give our UK lot a go. "It's clear you don't take care of your bike" errm no - my old bike is still running 97 Manitou SX Ti which are on original seals+bushings - which have lasted 5 years of XC racing. I build all of my bikes - road and mtb and have never suffered with any warranty problems before. Add that to the Scott with the Fox gets put in the loft from September to March to save the XTR, Genius shock etc being ploughed through the mud - and so I reckon I take pretty good care of them.

"Well in that case you must use commercial cleaner which has stripped the legs" - No again, just a sponge and water.

When I told them, the internet review sites were full of people complaining of leaky seals, the users of such sites are "idiots, simply life's whingers with nothing better to do"

Similar Products Used:Reliable old Manitou SX-Ti's.
Bike Setup:Scott Genius RC10
Bottom Line:The irony of this site is the number of similar reviews means that I can't flog these on ebay and get shut. So having spent all my cash on buying the best I've actually got rubbish and no change for some reba's!

Bottom Line:Outstanding fork once you learn to use Enduro seals. It cost me $75 to have the fork rebuilt at the local bike shop and that included Enduro blue seals. Ever since, not one drop of oil other than a normal light haze. This fork is undervalued for something that is easily fixed. Just don't use the stock seals. Hope this helps with the fork reviews from below.

Strengths:It doesn't leak oil on the first day you own it.
Weaknesses:THE SEALS LEAK. Seals leaked on both my '04 and '05 forks.
Bike Setup:04 Specalized Epic Disc
Bottom Line:The seals leaked. I had my shop send the fork back to Fox. It was lost. For months. Fox did send me a new (2005) fork along with a pump (you know, for the inconvenience). You'll never guess what happens: THE SEALS LEAK.

The 90 day warrantee for seals really sucks.

So here's a question for Fox: THE SEALS LEAK!!!!

My shop charges $40 for the parts and $20 labor. IF you want to keep oil in the strut so it doesn't dry out and score the cylinder or otherwise permanently damage the fork then this is the gift that keeps on giving -- as in MONEY to Fox.

Price Paid: $650.00
Strengths:When it works, it works great. Inertia valve is great for climbing. Initally a superb fork.
Weaknesses:Seals, seals, seals....they leak continuously. The inertia valve also broke (2-weeks after warranty). I only ride cross county, no big hits or drops. The seals only lasted about 300 miles before they went, and the inertia valve went shortly after that. Basically I have a $650 pice of metal in my garage. FOX "customer support" was not very supportive once they found out that I was two weeks outside of the warranty window!!
Similar Products Used:Manitou Minute 1, 2, and 3.
Bottom Line:Unless you are a bike mechanic and/or really like working on your fork continuously to keep it working, I would not recommend this fork to anyone. You can buy better for the same money.

Duration Product Used:1 Year
Price Paid: $700.00
Purchased At:Roaring Mouse Cycles, SFO
Strengths:This is a follow up from my previous review (ie: after having owned the forks for ~15 months)

Stable platform valving works as advertised. Seems quite stiff
Weaknesses:(1) Crown head assembly!!! After nine months of ownership, these things started creaking like there was no tomorrow. The stanchion tubes had warped within the crown so I ended up getting an entirely new crown head assembly. Fast forward another 5 months, and I am in exactly the same situation and in need of an identical repair!!! I have not abused these forks - I ride a 4" Titus Racer X and frankly, I am too chicken to hit anything more than a two foot drop!!!

(2) Fox (Australian) Customer service - my warranty claim was denied by Fox's Australian Representative as it was alleged (assumed?) that I must have had an impact or abused these forks to have bent the stanchions. I can appreciate that Fox must see all types of cases, but I know my style of riding and I NEVER mis-treated these forks. Like I said, I am a 38 year old that rides like an XC chicken! Despite explaining my riding style and asking for technical specifications used for their decision / assessment, I was fobbed off.
Similar Products Used:None previously, just starting to look for replacements now.
Bike Setup:Titus Racer X100 (Ti), Fox RP3 Rear Shock, Sram XO Rear Der & Shifters, XTR Front Der, Magura MArta SL's, XM819 UST Rims, Hutchison Spider Tyres.
Bottom Line:Two crown head assemblies in 15 months??? Whoa, something is up. When working, these forks perform well - I liked the conering stability and the way the inertia valving works. BUT the durability of these forks leaves a lot to be desired, which is completely unacceptable given the price paid for these. Apologies for the compelte turnaround from my first post below - the honeymoon is well and truly over :-(

Sorry Fox - between poor product durability and customer service that is frankly, nothing sort of insulting (at lease through your Australian importer), I doubt I will ever use any Fox product again.

Strengths:Stiff, solid
Weaknesses:Way too heavy, needs that one hit to activate the fork
Similar Products Used:SID's, other Fox's, bombers
Bike Setup:YETI asr-SL
Bottom Line:OK, if you race, I say forget this fork. Just was way too heavy for me and made the front-end an anchor. IF you are a trail rider and you don't climb a ton (or hard technical climbing), then this fork will work fine. The RLT did feel lighter, and was a decent 100 mm fork; however, I wouldn't buy this fork again. Oh, and the seals were weak.

Strengths:The smoothest fork I've ever ridden!!! Beefy stanchion are stiff and track really well!
Weaknesses:Bad seals, way bad!!!
Similar Products Used:Rockshox SID (98-2002), they are similar only in that they are air shox. Psylos, Marzocchi Z-1's
Bike Setup:Santa Cruz Superlight
Bottom Line:The performance of this product is remarkable. It's smooth, way smooth. And the inertia valve works better than I'd expect. BUT and there is a "big but". This thing has bad seals! I don't know if it is R&D or what but I've already gone through 2 sets of dust wipers(seals) in about 600 miles. I'm light, I'm a finesse rider, and I keep this thing clean, and I'm an experienced bike mechanic. A lot of reviews reflect the same sentiments so beware--if you like overhauling suspension forks like I do, no sweat. But if you think a butter knife makes for a good screwdriver, you might consider selecting a different fork. The F100X will require at least one overhaul per year so after spending almost $800 on this thing, if that sounds reasonable, then this is your fork!

Duration Product Used:6 months
Price Paid: $385.00
Purchased At:eBay (used)
Strengths:1) Automatic lockout simply has to be ridden to be believed
2) Climbs so well, I can almost take it rock climbing
3) Bump-threshhold and rebound damping adjustability
4) Smooth, stiction-free action
5) All metal; no cheap plastic; beautiful!
Weaknesses:None (and I have >300 miles on it since I bought it used)
Similar Products Used:Rock shox, Manitou (various forks, but none of the newer, stable platform ones)
Bike Setup:2003 Sugar 3+ (new warranteed frame Feb 2006): "Stock" (except Deus XC cranks, SRAM Rocket triggers, Avid SD-7's, King headset, Time ATACs, and Kenda Nevegal 2.1's)
Bottom Line:1) Uber-expensive, so I bought mine used (on eBay) to try it. You will be absolutely, utterly amazed at how it the Terralogic performs. (It is so stupifyingly good, I can't believe the other companies are even still in business anymore.) You can attack every climb completely out of the saddle with ZERO bobbing. Incredible.
2) This fork is almsot spookily clairvoyant the way it reads the trail: fully rigid on climbs, immediately plush at the slightest bump from below. It does the thinking for you so you just ride. If you are a trail rider (and not a huckster) you have just got to try this fork. I'll never ride anything else (I've also got an F80X on my singlespeed).
3) I got mine used, have >300 miles on it, have never, ever done any maintenance (aside from occasionally wiping the stanchions), and it performs flawlessly. I never add air. No leaking seals ever. (I'm 180# and I just ride twisty, steep, loose, rocky desert singlerack (no hucks, no jumps over 2 feet vertical)). If that's you, then this is your next fork. Fox forever!

Strengths:I love the intertia valve technology! it really works for climbing!
Weaknesses:Although the intertia valve works great for going up, I dindt like it when going down in some types of terrain. for example stone pavement , durability was baaaad. its so damn expensive
Similar Products Used:psylo race, marzocchi Mx comp
Bike Setup:zenith lanin, marzocchi, xtr, lx, easton, crank bros
Bottom Line:I really liked this fork. I had to get used to the lockout because jumping got kinda trickier because the fork didnt compress like a normal suspension fork. For climbing, It was great, I love that the fork got stiff by itself. When going down it was also pretty good, although on some types of terrain it didnt work as it should and my hands got numb. what really was horrible about fox is its durability. they start leaking oil pretty bad and soon. the intertia valve starts getting "soft" and doesnt work as well as it should. although constant mainteinance will keep this thing running ok. this is a full XC suspension fork, although I jumped with it a lot, it still worked fine for the whole year I had it on my racing bike

Bottom Line:I have a new bike. After putting in alot of research and discussing the options with my LBS I decided to use the F100x fork. It took several rides to "bed in", after which it rode great for about 2 months, and I completed several cross country races. Then during a recent ride the travel abruptly reduded to about 1 inch, luckily on a training ride and not while I was out of the country on a race.

It is being repaired under warranty. However, for a fork that Fox sells as their top of the range one, at one of the higest prices around this sort of thing is inexcuseable.

Unfortunately this fork is the weak link on the whole bike.

FOX. You need to read these forums. You need to replace your production seals with ones that work properly and don't leak. If you product is not up to spec then you need to lower the price accordingly. We, the customer, don't like paying above average prices only to have the product sitting on the workshop floor being repaired.

And if you tell me this is only an occasional occurrance with fox products, then I will tell more about the last fox prouct I bought, a Fox Vanilla front fork.......but thats another story.

Favorite Trail:Blue Mounds St Park
Duration Product Used:1 Year
Purchased At:JB Cycle
Strengths:Inertia valve design works. It locks out, but still sags. A very stiff fork. Tracks well. Smooth travel once the inertia valve activates. Threshold adjustment works.
Weaknesses:Seals are junk, replace them with Enduro. The fork has a cheap paint job, brake cables rub off paint easily. "Harsh" ride feeling.
Similar Products Used:Fox F80RL, Mantitou Skareb SPV
Bike Setup:Giant XTC composite 06 w/ Sram X.0
Bottom Line:A great fork because it is perfect for XC racing. It is stiff enough for the most powerful sprints and descents, but it is plush enough for smooth travel when you need it. The inertia valve design works well, but you need to set the threshold adjustment just right. Too much threshold and the valve will not open while you are seated, and too little and the vavvle will open when you stand on semi-rough ground.

Invest in a pair of blue Enduro seals ASAP, the stock ones will lead on you for sure. Other than that, and the cheap paint that rubs off easily, a great fork.

Strengths:Absorbs small bumps very good. It is good looking. Somewhat light. Somewhat tough.
Weaknesses:Seals started leaking on the first ride. Doesn't work well or at least not as a marzocchi in reapeated, large bumps or while punishing it. Automatic lock-out worked well for about a month, now it bobs lightly. After about three months, it already had game and a wobbly feel.
Similar Products Used:Marzocchi.
Bike Setup:KHS 904r stock.
Bottom Line:When I took my first ride on this fork, I took it easy. I was amazed by the feel of the fork. However I noticed a bit of oil in the seals that I thought was normal until the fork was used a bit. After a month, the fork's legs were covered in oil all though I kept cleaning it. Because I followed all the maintenance schedule, I was surprised that the fork was dripping oil. I decided to have a full overhaul for the fork done. After that, I obtained no difference and problems kept bothering my ride. Tired of it, I decided to open it myself. I replaced the o-rings with an aditional seal, and tightened the original seals and dusters springs.
Now my fork doesn't drip oil, but automatic lockout doesn't work as when it was new, and it has already developed game.
Durability: O, nothing, inexistent.
When thinking in a supension fork, think only in a Marzocchi if what you want is to ride and not to think about hydromechanics.

Similar Products Used:Marathon SL
Bike Setup:Trek 9.8, XTR, Racelight Wheels, some carbon stuff
Bottom Line:I have waited a full year before I submitted my review.
I have to admit I was a little scared buying this fork because of the seal issues. I slapped the fork on April 2004 and used it a ton. It took a while to get it dialed in but once I did,it was butta. It really soaks up small chatter bumps as well as pretty big ones. You need to play with the dial on the bottom to make the fork effective. It will drastically change its plushness.
In the summer a seal became leaky. I knew this going in so I sent it off. It took 2 weeks to fix, and it was still under warranty so it cost me nothing.
You really have to clean those seals after or before every ride CAREFULLY!! Run the rag from the bottom up on the stanchions, not from the top down. This is the key to keeping the seals working. This will prolong the life of the seals and your fork.
I slapped the fork back on and have had NO problems whatsoever. The fork is solid. If you race, this is a must.
Just two weeks ago I took the fork apart and replace the oil and rebuilt. I did this because I noticed it wasn't functioning as well as it should. I must admit I was intimidated opening up such an expsensive fork but it was quite easy. Now I like the fork even more. It is simple to take apart(you need a torque wrench) and overhaul.
The fork is working like it is brand new. High performance means high maintainence. Just do the work. Great fork.

I also love to fly back down and the fork has all the plushness of a Float or Talas. The inertia valve seems to work perfectly.

No complaints, this is the best fork I have ever used. If you are sick of messing with lockout and travel adjustments, this is your fork. If you can find one for less then full retail go for it, full value, A+ rating.

Strengths:Inertia Valve (in other areas of the country)
Weaknesses:Inertia valve (here in San Diego)
Similar Products Used:Fox Float 100 RLC
Bike Setup:A Single Speed
Bottom Line:Here in San Diego, the trails are bumpy. Really, really bumpy. Under the conditions we have here, the inertia valve, doing exactly what it is supposed to do, kinda bites. Since the trails here are mostly an unrelenting series of babyheads, the Terralogic becomes a pretty rough-riding fork as it constantly locks and unlocks itself. My Float is far smoother over the same terrain. I wanted to try the terralogic out, but I can't say I prefer it over the regular Float at all. In fact, I am going to sell the F100X and buy myself another Float. I don't really gain much from the lockout- in fact, I'd say it more of a hindrance than a help. That said, it does exactly what it is supposed to do.
On another note, the seals blew up the other day, on a section that really wasn't all that rough. My Float, though, has been perfect.

Bottom Line:As you can see from above I have kinda contradicted myself on the autolockout(intertia valve). I have ridden the bike three times and as much as the inertia valve does what it says I can definately feel the fork going from open to close with a bump, but I see from other postings this may bed in at later date. The negative aside, when the fork is working it is so plush with no tracking whatsoever. I would definately recommend a Fox forx over anything else. The fork is also light and well built (no plastic at all).
This fork can be used by anyone who rides mountain bikes (no categorizing here!!) I will post again once I have ridden the fork for a couple of months, cheers.
ps You will see from above, zero price paid, thats 'cause it came with the frame, but I believe in the UK they retail at £600-£650.

Strengths:inertia valve locks fork, yet unlocks when needed. Stiff. Smooth lines makes sharp looking fork.
Weaknesses:Front skewer must point forward (10 oclock position), unlike other which allow vertical skewer closed position.rotor looks really close to fork leg. Price, but I'm not looking at the bill, so it isn't a weaknesses. :)

Bike Setup:Titus Racer X, Hope C2 brakes, SRAM X.0, King Wheels, the essentials
Bottom Line:The performance of this fork was amazing. I'm still marveled by how it locks out during those touch out of the saddle climbs. I'm a anti-bob freak, who would rather loose plushness and travel to avoid bob. Well this fork works great. I didn't truely see how well until a rough rooted section of my local trail. If you can demo one of these, do it. This is the best fork I've ever ridden.

Strengths:Stiff; Plush; Quality Build; Adjuster operation; Interia Valve stops bounce when hammering.
Weaknesses:-Takes a number of rides for the inertia valve to start working super smooth;

Similar Products Used:Judy SL, Psylo XC, Skareb Comp, Sherman Firefly, Duke Race
Bike Setup:Turner Burner with Swinger SPV shock, built for XC and Marathon type riding & racing - long and low. I'm 6'4" & 210.
Bottom Line:After the first couple of rides I had real regrets about buying this fork over the regular Float. It seemed to lockout all the time, even in bumpy terrain with the threshold set at the lowest level. I was hoping for something plush in the bumps and it wasn't delivering.

I've perservered and now it feels like the inertia valve spring has broken in or something - it's now almost totally seemless in operation (getting better all the time) - stays plush when you hit the bumps but locks up solid on the smooth.

The slow compression bleed characteristic means that even though the fork is effectively locked (absolutely no bouncing around), it will lower when hammering up a smooth climb - improving the geometry of the bike - very nice.

I've noticed that anti-bob forks are far more effective at reducint bob than anti-bob rear suspension when standing. I find that standing is when I'm most likely to get any type of bob - tired or pushing a big gear for a sprint or short climb as there is usually more weight over the bars. When sitting I have a smooth pedal stroke that induces almost negligible bob in either end - even on my pre-SPV Giant AC.

I've not used SPV-type forks but have an SPV shock on my Turner and I think the inertia valve is a better way to go - there is definitely a loss of sensitivity to small bumps with SPV-type damping whereas the interia valve is completely plush.

This fork is best suited to XC racer types or Marathon riders who can't live with bob. Personally, a bit of suspension movement doesn't bother me at all, especially for a 100m fork: I would probably be just as happy with the regular Fox Float Forx. Having said that, they are fun to ride with and I'll probably find them indispensible in a few months time.

Strengths:Inertia Valve. Very Stonr, Accurate and Plush.

Bottom Line:I bought this fork for another bike build, and was going to use my 2004 TALAS RLC on this bike. Well this fork is so good for my riding that it isn't going anywhere, and I will live with less travel. It is extremely accurate and stiff when braking, but it's the inertia-valving that works so well. I can't live without it. I no longer start a downhill with those lockout-forget-blues..... This fork opens up when it hits something, and then closes and is locked when I hammer, climb or ride on the street to the trail, and no thinking on my part. Also seems a bit plusher than my 2004. This forks works great for XC and Trail Riding. I ride a hard 80 miles per week, dry loose and rocky AZ trails, and this fork delivers the ride.

Strengths:It works just as it was advertised. Tracks great, less front end dive when laying hard on the front breaks, and easy to set up.
Weaknesses:Pricey, but worth it!
Similar Products Used:Used to work in bike shops for years, and tried them all.
Bike Setup:Ellsworth Truth with F100X, Float AVA R PP, Sram XO, Hayes Disc, CK Hubs/HS, RF Deus cranks, etc....
Bottom Line:I got it more as a curiousity because most that had tried the 2004 model loved it. I love the fact that it really does know the difference between impacts and rider input. There is no front end dive when you hit the front break, so it's more effective than like on a typical fork when you hit the front break and your weight is pitched forward causing unbalance. The thing is super stiff and tracks great. Though a little on the expensive side, I figured that it is definatly not the dumbest thing I've spent money on. I'd buy it again if given the chance.

Strengths:Strong fork, tracks really well. Super Plush on the big stuff.
Weaknesses:Cost!
Bike Setup:'03 NRS 1
Bottom Line:I posted an initial review after riding mostly cross country single track out here in SoCal. This past weekend I took it on Noble Canyon, probably our best local ride with technical sections. It was great. The fork tracks extremely well. I no longer question where my wheel will go after hiting a rock like I did with my SID. I am now used to the geometry of the bike with the 100mm fork vs the 80mm fork. Like I said, it tracks extremely well and is super plush when you hit anything hard. Great fork. Worth $700? I don't think so. If you can pick it up for anywhere from $500-650, I'd say it was a must buy. But for $700+, I don't know. However, I am sure that once I get back out to Moab, it will seem to be worth every penny.

Similar Products Used:04 F100
Bike Setup:On 04 S-works epic
Bottom Line:Had a chance to ride with the new fork for the first time atthe Endurance 100 race at Park City, Deer Valley, and the Canyons. Sweet sweet ride for its first 100 miles on some challenging Wasatch single track. I felt and had the utmost confidence despite being on the fork for the first time. The fork gave precision handling and it seems durable. I remember when I picked it up from the shop - the front end seemed alot lighter than before - I don't know how much lighter the o5 is, but it was noticeable. Will confirm on it's durability after a couple of more ultra's and 24 Hours Solo. If it comes through I'll be a true beleiver in Fox. Had the 04 model and was not stoked.

Strengths:Super plush on big hits. Very stiff in terms of flex/tracking.
Weaknesses:Cost.
Similar Products Used:SID, HeadShock
Bike Setup:'03 Giant NRS1. XC risers, fox f100x fork, hayes hyd discs, and mavic ust wheelset.
Bottom Line:Great fork. Haven't hit anything too technical yet. Hopefully it will cool down and I'll hit Noble Canyon next weekend for some technical stuff. It has been super plush for what I have ridden so far (~30 miles of XC single track). Terra logic lockout feature works as advertised, and is a breeze to set up. Also as advertised, it won't stay locked out if you get out of the saddle to hammer on the pedals. One word of caution if you are stepping up from an 80 mm fork. Going with the 100 mm fork, the geometry of the bike has changed a bit, with the head tube now higher. Makes it feel more stable on technical stuff, but it also places more weight over the rear shock, making the rear shock more active during climbs (even on the NRS). I don't yet know if I like the fork in all conditions because of that. Maybe I should have stuck with 80mm? Is this why some guys have said that they tried 100mm and decided they are better off with 80mm? I know it will be great when I go back to moab. But for SD, I still don't know. I'll post again once I get more miles on it. But, for now it is a great fork, if only it wasn't so expensive.
