Strengths:    Stiff, pretty plush, Cheap, Looks Awesome, takes a beating

Weaknesses:    pain in the rear to replace seals, and bushings at home. (BUT IT CAN BE DONE!)little heavy, no on the trail adjusting.

Bottom Line:   
It's a great fork for the price, and it gets the job it is designed for done. Absorbs bumps wonderfully, and pretty good when going off a curb. Not the best for mid sized and larger drops though.

It could be a lot better with some on the trail adjustment knobs.

Strengths:    Stiff, looks, weight, cost..

Weaknesses:    Serviceability, on the fly adjustment non-existant

Bottom Line:   
Pretty decent, middle of the road fork. This was a huge upgrade in looks and performance from the crap that came with the bike. Marzocci doesn't dissapoint that is for certain. Highly recommended for those who have an older fork or low end fork and want to get a well performing fork, that won't break the bank. Four overall chili's because of the lack of adjustment on the fly.

Weaknesses:    a little heavy

Bottom Line:   
These guys are awesome - I was riding my MTB to work doing about 40km along a city street, Dude opens his car door, bang! these shocks took it front on, not a problem, I hit the door so hard my straps pulled out of my backpack. But the shocks kept on rockin' I have used these for 24hr races, freeride and some light DH, big and little. A great overall shock for price.

Submitted by Will a Weekend Warrior from Bath

Date Reviewed: February 15, 2006

Strengths:    For the price it is strong enough to cope with a fair amount of abuse, the air cartridges, after a period of bedding in, provide a smooth, buttery compression (easily adjustable if you've got the pump). Full air setup means that it is very lightweight and perfect for XC although, if at a high enough compression, can also be used for moderate jumping and dropping.

Weaknesses:    Do not run this thing on a low PSI for dropping, if you do there is a great chance that it will bottom out harshly and throw you off (believe me i know from bitter experience). Air cartridges are prone to leaking after a time and need replacing. Rebound adjustment uses a fiddly internal allen key system but unless your an adjustomaniac its no big deal. After a few years proggressive riding you will probably want something stronger and with longer travel, especially for the big stuff.

Bottom Line:   
If you're an all round or new rider looking for decent budget fork for starting out or all mountain then look no further, this is for you.

Submitted by Martin a Cross Country Rider from Adelaide

Date Reviewed: February 12, 2006

Strengths:    Tough, solid, almost maintenance free, no air leaks.

Weaknesses:    No external controls (damping, etc)

Bottom Line:   
Love this fork. I've got mine set up to be almost rigid over smaller stuff and to become active on serious hits. It still takes the edge off gibber and rattle bumps though. I run mine at around 40psi, which is a tad high for my weight. Personally I don't think I'll ever go back to a coil, or coil/air hybrid. I love the adjustability and feel of air now.

I'm glad I found this fork. After the Judy SL I was really unimpressed by that style of fork. The only thing I miss on this one is an Aluminium steerer tube and ETA. Maybe one day I'll upgrade to the MX Pro ETA or Marathon and I'll give the Comp to my GF. I'm just a bit worried it will outlast her bike though.

5 flaming chilis for value and 5 chilise for getting me interested in riding again.

Weaknesses:    None yet. However the weakness might be I have only riden one other shock.

Bottom Line:   
From the very first ride I noticed a marked imporvement. I almost thought I had a new bike. If you want to upgrade from a cheap stock shock, go for it. It is worth every penny. Best upgrade I've made.

This upgrade made my bike handle like a caddy, of course anything but the RST Gila T5 would be an improvement. Forks holds air great, stanchion tube seals work perfectly. Of course, the only downside it the great Marz popping noise that everyone loves. Would totally buy again!

Submitted by Tony a Cross Country Rider from Scotland

Date Reviewed: April 8, 2005

Strengths:    Strong Build, Can absorb the small bumps as well as the boulders, makes your ride feel so good! Cheap for 120mm travel.

Weaknesses:    Requires a shock pump (sold seperatley) for any adjustments.

Bottom Line:   
Overall i was very suprised with the performance of these forks, they come plastered with stickers telling you not to use the fork for anything other than XC, but the truth is they can survive and perform for a lot more!
The forks take a while to brake in and makes some squelchy noises to begin with, but even straight out the box u'll notice the diference on your bike ride, much smoother, with great rebound settings (i have not touched mine as they seem perfect).
For the £140 (about $300) i paied for my 120mm travel set they are a bargin!

Only downfall i can find is that a pump is required to adjust anything and possibly the uphill ride is harder as these forks compress a lot easily, but overall this is a muset for anyone wanting budget fork.

Strengths:    Price. Weight. Great Value. Low maintenance.

Weaknesses:    Internal rebound annoying if you require to change your PSI with the trail style. Took a few months to wear in.

Bottom Line:   
Great value folk offering 105mm of travel and zero maintenance. Had these on my previous hard tail Kona and did nothing to the folks and they peformed perfectly.

Then took them to my new Sub 5 and with the added jumping needed to pump up the air and keep messing with the rebound (which requires taking the top end's apart on both legs and messing with internal rebound which can be ticky to adjust. To conclude great folk, but my next set will have external rebound adjustment to make life a litle more adjustable!

Date Reviewed: September 24, 2004

Strengths:    Low price, strong build, excellent shock absorbtion.

Weaknesses:    None so far.

Bottom Line:   
This MX Comp beats all similar priced forks I've ever tried. Already from the first ride, I was amazed how progressive and smooth this fork is on rocky terrain. If you stand still and try to compress the fork, it can feel a bit stiff (espacially when new). But when riding, it's surprisingly plush. I spent some time adjusting the air pressure, and found the best level a little below what's recomended in the tech manual.
If you're looking for a good value for money fork (and not focused on low weight), load the MX Comp Air. It can compare to much more expensive forks.

Submitted by Clive Norton a Cross Country Rider from Yorkshire, UK

Date Reviewed: June 19, 2004

Strengths:    I have the 105mm travel MX comps.
Solid build quality (no plastic in sight, all metal except the very substantial rubber seals). Yet light. About 1.8kg.
Very progressive compression, from tiny input moving a tiny bit, to seemingly impossible to bottom out without deflating them.
Easy to adjust - deflate to 30psi per side for the trail and up to 65psi for the road.


Weaknesses:    Fork seals are very substantial and take a few rides to get rid of the stiction present from new. This is probably more reassuring than a weakness.
V-brakes are fitted onto an extension pin rather than straight into the lowers. This seems to cause parallel link V-brakes (e.g. XTR) to resonate, but works fine with fixed pad designs (Deore).
I bought two MX Comps the same day (two bike family) and one is definitely stiffer than the other. It must have more oil in it, reducing the air volume. If it doesn't rain tomorrow, I'll probably pour some oil out.
The tamper-proof warning sticker looks out of place and is going to take me a while to pick off one day when I've nothing better to do. Do they really think that just as I get to a pot-hole that I'm going to stop, get off, and read the sticker on the inside of the fork leg?


Bottom Line:   
Light. Solid. Pretty. Smooth. Very progressive - from tiny movements up to difficult to bottom-out. They make the Rock Shox Pilot C's that I had before suddenly seem all-or-nothing.
They DO take a few rides to get rid of the stiction in the fork seals. But it just makes them seem even sturdier to me.
Can be inflated from soggy to very hard. Great for roads to and from the trail. Or to work when you don't want to waste a sunny day in the car so just pop on some skinny slicks and pump up the forks.

They almost lost a sunburnt Mr. Hanky for making parallel brakes vibrate, but they're just so wonderful that they still get 5/5.

Favorite Trail:   Mary Towneley Loop (75km)

Duration Product Used:   Less than 1 month

Price Paid:    $324.00

Purchased At:   Halfords

Similar Products Used:   Just upgraded from RockShox Pilot C. Absolutely no comparison. If you're trying to decide which to buy, buy the Marzocchi, even if it means you can't afford to buy brakes. Use your feet to stop until you can afford to buy brakes later on. Or get one brake and one wheel. Anything to get the Marzocchis and not the Rock Shox

Bike Setup:   Aluminium hardtail with full deore groupset (inc. hubs) except one V-brake is upgraded to XTR. Maxxis High Roller XC tyres or Panaracer 1.25" slicks depending what I'm doing.

Now then, when I fitted the forks, I obviously put the one pair of XTR V-brakes on the front. Bad move. They vibrate pretty badly. I tried toeing them in, out, round-a-bout, different pads, but no luck. Had to put the XTRs on the rear and move the Deores from the rear to the front. Everything works perfectly that way around, so no great loss
