    Strengths:    lateral ridgidity, stem, looks, plushness, 20mm thru-axle, everything else...

    Weaknesses:    a bit too soft (but could be changed with stiffer elastomers/MCU's), non-replaceable bushings, boots

    Bottom Line:   
    If you're lightweight like me (135lbs) and dont ride to hard, this fork is perfect for urban or downhilling.

    Strengths:    seemingly indestructable, stiffness, suspension action, tough finish, good boots(much better than manitou's), good 20mm through axle, adjustable integrated stem

    Weaknesses:    none so far, but if you are a small rider, may be a bit heavy & tall

    Bottom Line:   
    A very good performing fork, outperforms others. I got mine at cloeout, and I feel that anyone looking for a DH fork should go and buy one of these. I use mine for freeriding mostly, and havent bottomed it out, even off 5-6 foot drops to flat. Very durable, and the adjusters do make a difference that you can actually feel on the bike. I weigh about 165-170, and run the preload about half-way, and the rebound 3/4 of the way slow. Buy it and you will like it.

    Strengths:    Excellent For Downhilling

    Weaknesses:    Doesn't work to well for a 'sunday rider'
    May seem to tough at first

    Bottom Line:   
    If your not going to use the forks often you may as well not own them they need to be used a lot before they reach their full potential

    Date Reviewed: September 19, 2000

    Strengths:    Looks very sturdy and it is sturdy. Hight adjastable stem is nice, but I wish it could set the position of the handle bar closer to the rider (I'm 5'2" tall). I mostly take video by attacting small miniDV camcoder on my helmet and go donwhill. I mostly sit on my seat to go down each level of the trails (A, B and C), but this forks help me from falling from my bike. As matter fact, when I had to swap my bike from this to Mongoose Dual with RST HI5, the bike was too light and my body leaped over the bike and hit my bottom very hard. Previously, I had no problem with the same section with my Haro with Sigma forks.

    Weaknesses:    The weight. It's very heavy. My Haro MX2 came with RST HI5 and replaced to this set of forks and made my bike very heavy. It sometime get stuck until you push it harder. The Adjastment controls are hardly effective.

    Bottom Line:   
    Since I only paid 1K for this set of forks, the value rating is high (5 flamin' chills). If it was lighter and the adjastment controls are more effective, then overall rating would have been higher. XMO XL70 is the newer model I suppose, so I wish I could compare them. The dedicated stem is very cool, it gives more Motorcycle looks to it.

    RST HI5 it moves okay for the short stroke, but breaks easily. I know at least 3 people who broke them.

    Date Reviewed: March 27, 2000

    Strengths:    works really good over the whole travel, the damping system works perfect,because you use the whole 178mm , it doesn't work very progressive , so you use the travel you have.
    works even really good under stress (even it has a cartridge damping system).stiffness is better than all other forks I've tested.seems 'undestroyable',if you compare it with RockShox or Manitou DH-forks.A really good durability(nearly a whole season racing and it works as good as it did at the beginning).The rebound damping can be adjusted so it has the right speed for every situation.

    Weaknesses:    Needs some time till it works as perfect as it does now.

    Bottom Line:   
    Racers who want a product that works perfect , that can be used over more seasons , and who don't want to make some compromises should buy it.I'm sure , you won't be disappointed.

    stiff as buggery, look awesome, plush, exc. rebound and compression, great adjustment, awesome seals. perfect ammount of travel, bombs through the rocks like no other.

    non oil bath, but doesn't seem to affect performance. rather pricey for non sponsored riders.

    Bottom Line:   
    great forks that will swallow just about everything in their path, stiff and definately race worthy. top stuff!!!!
