    Favoriate Trail:Ohlone Wilderness Trail
    Duration Product Used:3 months
    Price Paid: $25.00
    Purchased At:The Bicycle Garage
    Strengths:Almost completely silent and very smooth ride on smooth pavement (unlike knobby mountain tires), excellent cornering.
    Weaknesses:Makes bike look weak and skimpy. Not much faster than the Specialized Resolution Tires (standard on 08' Hardrock models). Also hard to get off rims.
    Similar Products Used:Nothing like it.
    Bike Setup:2008 Hardrock Comp Disc
    Bottom Line:I switch back and forth between these tires and my Resolution tires to save the tread on the Resolution tires. These are great commute tires. If you ride your bike to work or school everyday, these tires are the best you can get. I also would recommend these tires to people who ride on the road for fun. If you spend most of your biking time on very rough roads, keep looking for another tire because these tires would get annoying after awhile. Every little bump is transmitted up the bike with these tires at 100 psi.

    for this kind of money you can get real tires like Schwalbe Marathons, Conti Sport Contact, Panny t-serves, etc. Sorry but Specialized is trading on their name recognition.

    Purchased At:Various locations
    Strengths:Very light & fast for a 26" tire
    Weaknesses:Thin sidewall (on older skinwall versions) is susceptible to cut flats
    Similar Products Used:IRC Metro 1.25
    Bike Setup:Cruiser (hardtail)
    Bottom Line:I've used Fat Boys off & on for about 15 years now. They're excellent tires for 26" street riding. Wet weather traction & cornering is only an issue on oily or dirty surfaces. I usually get about 1500-2000 miles out of a tire (rotating F-R every 400-500 mi or so). I had one with only 365 miles blow out through the tread, but I think it had been sitting around for a while before I mounted it. IRC Metro 1.25 tires (the older version with skinwalls) also pump up to 100 PSI, and I've gotten 3000+ miles out of the Metros, but IRC doesn't list that model anymore (only a lower-pressure version). To those who complain about road shock: I'll take a 100 PSI Fat Boy any day over a 100 PSI 700C road tire - the added cross section (but nearly-same rolling resistance) makes a big difference.

    Strengths:1) Super sticky. Grips to the road extremely well.
    2) Light
    3) Quiet
    4) Practically resistance free.
    Weaknesses:1) Difficult to mount.
    2) Once mounted onto the wheel, the side walls are thin and it was hard to get the tire to set right into the wheel. Patching a flat on these will be a serious pain. I'd recommend looking into carrying a long a fix-a flat type of device with you instead of pulling the wheel of to patch it.
    Similar Products Used:Kenda Krisp Hybrid
    Bike Setup:2007 Ibex Alpine 550, Marzocchi Marathon SL forks ('04), TruVativ Blaze cranks, Specialized Lo Pro Mag 2 Pedals
    Bottom Line:A great wheel. I'm worried about it's reliability in the long run as this is my first experience with it and Specialized Flak Jacket Technology but so far, riding has been a unique experience. Quiet, fast, corners insanely well and fun to ride on. It's like turning your bike into a stealth bomber. Recommended.

    Strengths:. They are THE Mountain Bike Slick
    . Grip, These things just hang on and on and on.
    . Puncture Protection
    . Warp Speed
    . Whisper Quite
    Weaknesses:. Mounting - hard to get on
    . WET WEATHER - DON'T BE A DOUCHEBAG - THEY ARE SLICKS, Slow down when it's raining, don't ride on grass, not dry grass, not wet grass, don't ride them on loose dirt, hard pack, hard over loose pack, mud, snow, ice, don't ride them downhill, ride them on the ROAD!
    Similar Products Used:Conti' Sportcontact
    Bike Setup:Giant Thermal2 trainer/commuter - completely standard
    Bottom Line:These tires are, quite simply the best slick for your MTB. They are extremely sticky, have a very low rolling resistance and they give confidence during hard cornering.

    Lets not be stupid. These tires are not intended for you to ride them on anything other than Tarmac or Cement, not hardpack, not loose, grass(dry or otherwise), not snow not anything else. Tarmac or Cement.

    There's alot of "These tires suck in the wet" in the reviews here. If it's wet, slow down, period.

    I've ridden these things for almost 4 years and through maintenence(picking bit of crud out of them) have never had a flat, never blown out a sidewall, nothing. I ride on some of the sh*tiest roads in Australia. Use them everyday and treat them mean they won't last for ever, you'll wear them out, deal with it!

    The biggest issue with these tires would have to be that they telegraph every vibration through your shoulders, if you're running 100PSi.

    Weaknesses:Hard to fit, can cause hairy moments if trying to stop really fast.
    Similar Products Used:2.3" MTB tyres!
    Bike Setup:Scott Voltage, few extra bits...
    Bottom Line:I used this for commuting to work, I was cycling about 200miles a week on them, they work fine in the rain and hardly lift any rubbish from the road. They stop you fine unless the surface is very smooth and wet, or if you're going really fast and trying to stop very quickly because a van has stopped right in front of you. Only got two punctures, both super thin sharp shards of flint, loved them only problem is that they really do transmit every little bump, but then they are truely amazingly fast!

    Strengths:very low rolling resistance, quiet (obviously)
    Weaknesses:craptastic wet weather performance.
    Similar Products Used:Specialized Nimbus, Ritchey tom slick, Avocet slicks, & a couple others I can't remember.
    Bike Setup:These are on a vintage mtb that won't give up.
    Bottom Line:I have a fair bit of experience with other slicks having used the nimbus to tour across the rockies and the avocets and ritcheys in the alps and while the fatboys are super fast, they do absolutely SUCK in wet or slightly wet conditions. I was reluctant (for awhile) to completely blame the tire as I use this bike for runs to the pub so operator error could very well have been a factor in a couple of wet pavement slideshows but last night they completely quit on me and dumped me on my ass for no good reason.
    ..I still like them for the low rolling resistance in dry conditions (and they're cheap) but am strongly considering relegating these to the trainer and picking up a pair that can handle a little variety in conditions.

    Strengths:This thing has awesomely low rolling resistance, just like everyone has said, it's quiet, it looks cool, and I just plain go faster.
    Weaknesses:I haven't found any yet other than the nervousness that has been inspired in me from people's warnings about treadless tires...
    Similar Products Used:These are my first slicks.
    Bike Setup:Older model Fisher Supercaliber, xtr rear, xt front, king hubs, bontrager race-lite wheelset, racemodified seat-post and bars, xt v's
    Bottom Line:I was looking for a set of slicks or light and fast semi-slicks for my mountain bike to make it go faster with less effort cause I'm planning on doing some long rides (150 miles for instance) with some roadie buddies. I picked these things up for 20 bucks, though apparently they were supposed to be 25, and mounted them fairly quickly (the roadies were hurrying me along). First thing I noticed; they look pretty cool, and I especially like the "Specialized" in white on the side.

    Then we were off for a beginning of season ride, my three roadie buddies on brand new carbon and alum speed machines and I. After about 20 miles, I kept up with them the entire way, and even led for some time, and was still ready for more at the end. Not to mention, I felt infinitely cooler on a mountain bike than I would've on a skimpy road bike, AND I kept up! What more can you ask for.

    I had been looking for continental grand prix mtb's after reading their reviews here, and stumbled across these. For 20 bucks (20 or 30 cheaper than the conti's I believe), I bought them, then came home and read the reviews, and then slapped em on, satisfied with what I saw. So far they haven't disappointed.

    I plan on swappin out my mtn bike tyres whenever I wanna ride the single track. These are great on the road, so they'll stay there. Now all i've gotta do is make my aero bars... (yes, make. Fiber-glass and foam... mmmm....)

    If I find any weakness (since it WAS only their first day), expect another review. But don't count on that.

    Similar Products Used:2 inch semi slicks

    Bottom Line:these roll much easier than my old 2 inch tires. I could run 2 gears higher with these slicks. I tested these tires today on some tame off-road (a grassy hill with some wet grass...) and they survived ok but most most importantly, they were awesome on the dry pavement. I recommend these to anyone who wants to shave a few minutes off of their commute. these tires are a cheap way to turn your MTB into a commuter that will hold its own against some of the road bikers. These tires make for a rough ride if you bike paths are in rough shape but for me the speed is worth it.

    Not TOO heavy
    Weaknesses:None
    Similar Products Used:Nothing lately. I ride Specialized's exclusively these days.
    Bike Setup:Yeti A.R.C.
    Bottom Line:Specialized Armadillo tires are arguably (no, make that no argument) the most flat-resistant tires ever made. However, they come at a price: weight. You didn't think all those layers of Kevlar were a free lunch, did ya? Well, the Flak Jackets are a step down in terms of puncture reistance, but I chose them because of the lighter weight. This is true for the Fatboy and the Turbos I run on my Tommasini road bike. I've been using Specializeds for about 8 years and during that time, I've had a grand total of...2 flats.

    To say that Fatboys don't perform well in the rain is pure hogwash. Ever hear the term hydroplaning? Well, it doesn't exist in bicycle tires! Why? The contact point is too narrow. You can find the test conducted by Jobst Brandt in Google - I'm too lazy to get the link. Hydroplaning occurs in automobile and motorcycle tires because of the wider contact point. In fact, having NO tread pattern on the Fatboys is why they perform better in the rain. Tread pattern/rain performance is one of the many urban myths in cycling. People see no tread and they immediately freak out.

    Anyhow, back to the Fatboys. Put these suckers on your MTB bike and it's like having a rocket ship on asphalt. Ride is a bit harsh at 100 psi, but that's what also propels you so fast. Get 'em.

    Bike Setup:Specialized MTB, TREK 830
    Bottom Line:Having decided that I wanted to do some road biking after shin splints became an issue in my running, I looked at ways to make that happen. Getting some slicks for my mtb seemed to be the quickest, easiest, cheapest way.

    I read many reviews of all sorts of tires and decided on these. They do not disappoint. However, they were a little difficult to find in the Baltimore area w/o a special order. The only place that had them in stock is notoriously the most expensive place to buy anything.

    They are worth every penny though. My first time out on them I tore 30 minutes off my 20 mile loop, and ran out of gears. I love them, and would buy them again, and again, and again.

    5 PEPPERS for these.

    Purchased At:Talbot
    Strengths:Very light, fast rolling, easy to install on rim after the first 3 times.
    Weaknesses:Very weak rubber compound on the sidewall. Cracks on the casing makes the tube extrude, leading to "explosive decompression", a.k.a. a flat tyre. Had a crack within the first week of riding, and then another about 2 weeks ago.
    Similar Products Used:Performance City Slick ST 1.5. Hutchinson Top Slick 1.2.
    Bike Setup:Trek 7000 8-sp commuter.
    Bottom Line:I had a lot of practice patching tubes lately. It has been a combination of both tyres getting old, and the FatBoy getting sliced on the sidewall. I fixed the tyre using a tyre boot from Park. But considering I did not have this problem on the Performance or Hutchinson tyres, I think Specialized needs to take a look at reinforcing the sidewall structure.

    I change tyres every week because this is also my XC bike, so the bead gets worked pretty good.

    I would not buy this tyre again.

    Weaknesses:Finger-bustingly hard to mount. Not the grippiest tyres in the word. I have some issues with tyre cuts.
    Bike Setup:Kona hardtail, giant hardtail, Giant Vt2
    Bottom Line:Very fast yres for your mountainbike. If you are a city fweller you will not regret purchasing a set of these! For the price, they're not bad. probably the elast rolling resistance of any skinny tyre designed for MTB's.

    However.. the total absence of tread/groove etc mean they are not wet weather tyres.On damp ground they're okay... in the rain they're just plain scary! I experienced severe aquaplaning on the front at speed(traffic sprint!).. *Although it was scary as hell.. it was somewhat strange too.. almost so that i want to try again in my own time!)

    Also, my tyres and that of some of my riding buddies have developed some fairly deep cuts lingitudinally... maybe glass, maybe hard grit.. maybe tram track.. but no-one has any recollection of running either of these things over!

    Have used these tyres for about a year and a half ... no problems yet... Although, it should be noted that these tyres can be "flatspotted" if you have a fairly hard lock-up.


    Conclusion: For the money - spot on. Use for fair weather days and you won't regret the speed and weight advantage of these tyres! - Give them a try.. you won't be disappointed. In fact, you;'ll probably start running out of gears on your MTB!

    Strengths:- The best looking commuter slick on the planet.
    - You can crank 'em up to 100 psi if you want to. They have extraordinarily low rolling resistance at that pressure, even compared to my ultra-swank road bike.
    Weaknesses:Mediocre traction and wear rate.
    Similar Products Used:Tioga City Slicker (1.25").
    Bike Setup:My faithful commuter is a 1992 Cannondale Delta V hardtail with a rigid fork, new Tiagra crankset, bargin-bin 11-23 8-speed Dura-Ace cassette, and other wacky but super cool retro odds and ends.
    Bottom Line:These are wearing considerably faster than my Tiogas while offering considerably less traction.

    100 psi is very convenient if you ever choose to, say, go on a long and fast road ride with hardcore roadies before you've bought yourself a road bike (just take my word on this), but too firm for general commuting.

    They're average tires at best, but I might buy them again simply because I don't ask much from my commuter slicks and these look super cool.

    BTW, I don't recall if they ever came if other sizes, but I'm running the 1.25" version.

    Strengths:Relatively high inflation pressure, low rolling resistance, small contact patch, decent puncture resistance.
    Weaknesses:Weak sidewalls.
    Similar Products Used:WTB, Panaracer, Ritchey, Michelin, etc...
    Bottom Line:Prior to purchasing a road bike (or two), I was putting considerable road miles on my mountain bike. In search of a low rolling resistance tire for 20mph+ flat speeds, I eventually came upon the Fat Boy. Perhaps the closest thing to a road tire I have seen in the 26" size, it performs its job quite well. Low rolling resistance, good flat protection, decent cornering / handling, and moderately high pressures. However, the sidewalls are terrible. After multiple sidewall blowouts on different sets of rims, I gave up on these tires. I never put more than about 500 miles on them before a blowout. Other than these tires, I have always had to replace due to tread wear (or cuts for road tires). Overall, I think these tires give a mountain bike the closest chance of being a road bike of any tires out there - but it comes at the cost of always carrying a tire boot...

    Bottom Line:These slicks are great for using your mountain bike on pavement. They're fast and they hold their air (100 psi). I haven't had a flat - they have some sort of puncture protection that seems to work. The price is also right.

    Strengths:Fast, no road noise, seemingly indestructable. Only MB tire I found that is rated at 100PSI!! Wonderful pavement cornering, maybe even better than a road bike.
    Weaknesses:Easy to loose traction when starting on wet roads. Useless on wet grass (duh!). Dropping off a sidewalk onto the road at 100 PSI with no suspension really hurts! Never seem to be onsale either.
    Similar Products Used:A really old pair of Fat Boys (1990?), various no-name tires with the stripe down the middle.
    Bike Setup:Pro-Flex K2, full suspension.
    Bottom Line:I bought a pair of these somewhere around 1990, and rode them a bit then, and loaned them for others to try.

    Just put them back on this spring -- they had some nasty looking slices, dry-rot, etc, but still worked great, and a couple hundred more miles without a flat.

    I just replaced them with newer all-black versions, as I didn't know how much longer I could trust a 12 year old tire. Same great ride, but more peice-of-mind.

    These tires do surprisingly well on hard-packed gravel, and occasional dirt, but really accel on the road.

    It may seem to ride a full-suspension on the road with fatboys, but the ride is smooth and comfy. I have absolutely no worries about crappy roads (they are grinding the roads here before repaving), potholes, or riding on the shoulder under traffic pressures.

    Strengths:Low rolling resistance
    Weaknesses:Hate putting them on and off
    Bottom Line:These are good tyres but don't buy them if you to MTB. I don't like slicks full stop. There real hard to take on and off, and their only for road.

    If you do MTB buy MTB tyres. If you do Road buy a road bike, trust me these tyres are not worth it.

    If you have a MTB and only ride road, these are good tyres but who in this world is that stupit. That's what they made road bikes for.

    Similar Products Used:Conti Grand Prix, Michelin Wildgripper City
    Bike Setup:52T single Tiagra crankset with single LX shifter. Deore rear derailleur/LX cassette. X221s with Deore V's. Specialized rigid cro-mo fork. Conti Grand Prix 26 x 1. Claude Butler 7005 w/Cane Creek integrated h/set. Deda Nero stem.
    Bottom Line:I can see various aspects of my experience of Fat Boys evenly distributed in the reviews below.

    Ran these for over two years without a murmur of complaint. Whilst amazingly never had a puncture, there are loads of cuts (from glass) and they look quite deep. Still on original inner tubes though but do remember that they were OK to get on to my rims.

    The most noticeable differece about getting slicks is the glorious lack of road hum from the tyres. Also, you do go considerably faster and routine journey times are noticeably shorter.

    Handling in the wet is hairier than with my present Contis and am not completely certain why. Someone suggested to me that the contact area is larger in the Fat Boy's compared to my 1 inch Contis (which also have tiny grooves at the edges) and so you may get some kind of 'aqua planing'. Quick traffic light starts in the wet are sometimes a bit messy as is cornering. Not sure how much of this to take on board since one should ride a little more cautiously in the wet when there is traffic around anyway. Drain covers and painted lines in the wet as usual are lethal - avoid.

    All-in-all, I am picking at tiny points in what was a fantastic (first) experience with slicks. They ride well, look cool and last. So why did I change? Well - I just wanted more straight-line speed and hence changed to a thinner tyre. I still have the Fat Boys on my hack but if you are an experienced rider (that would be most of you), I'd highly recommend the Conti Grand Prix's.

    But as a first time slick - the Fat Boy is the one to go for. If you love riding and you also commute, your best investment this century will be a pair of slicks. Try these - your view of urban cycling just might change forever. You have been warned!
