    Favorite Trail:petes wicked (Batchler st, Granby MA)
    Duration Product Used:1 Year
    Price Paid: $150.00
    Purchased At:N/A
    Strengths:Good for light people
    Weaknesses:not enough travel and strength for someone 160 pounds or more
    Bottom Line:These are the worst brand forks ever, i hit a jump 1 1/2 feet high and they exploded and i got all of the internal parts shot at my face. it blew up cuz they made the top cap out of plastic not metal so somthing was going to happen eventually. my injuries were concusion, neck problems, scars on my face almost loss of teeth.

    Date Reviewed: October 5, 2006
    Duration Product Used:6 months
    Strengths:Everything
    Weaknesses:None
    Bike Setup:Trek Fuel 70
    Bottom Line:For the money this is a really great fork. I am planning on using it till it wears out completely. I was under the impression that this fork was going to really suck, but I am completely satisfied with it. I have taken it through about anything imaginable and the fork still works as if it were brand new. I will probably upgrade to a better shock when this one wears out, but if you are entry level, this is perfect for you.

    Date Reviewed: September 7, 2006
    Duration Product Used:1 Year
    Strengths:Cheap, trusty, Lockout is very handy
    Weaknesses:not stiff enough, not enough adjustability for my liking
    Similar Products Used:This came standard on my setup but have since upgraded to a Recon
    Bike Setup:Scott frame, SRAM x7 drivetrain, Recon fork, Shimano mechanical discs
    Bottom Line:Good fork for someone starting out
    ... good value, some (albeit limited) adjustability, indestructable.
    Lockout works a dream.. only allows 1 or 2 cm travel to dampen slight bumps... good for hill climbing.
    Its still working as god as the day i took it out of the shop - ive never done any maintainance on it except for wiping the mud off it.
    You will find yourself bottoming it out on bigger stuff.
    I dont know how it would go if you were doing lots of jumps, big drops, etc.. i stick to XC
    Expect to 'grow out' of them after a year or so

    Favorite Trail:Cedar Glades
    Duration Product Used:6 months
    Price Paid: $79.00
    Purchased At:Blue Sky Cycling
    Strengths:sturdy 4130 steerer and uppers. Price. A little on the heavy side but you cannot really feel it.
    Weaknesses:Spring preload knob is plastic. No compression\rebound dampening adjustments other than changing oil weight.
    Similar Products Used:First "judy" level fork I have ever tried.
    Bike Setup:06'Redline cromoly SS.
    Bottom Line:After changing the spring and the oil weight to suit my weight It worked very well and the 4130 steerer has good grip and strength for my bar tugging single speed riding. For the price I think it cannot be beat for cross country riding. It was a perfect match for my cro. frame SS. I was more than pleased.

    Date Reviewed: May 31, 2006
    Duration Product Used:3 months
    Strengths:cheap
    fairly plush
    quiet
    good pre-load adjustment range
    able to change rebound damping
    Weaknesses:could be stiffer
    cheap construction: plastic everywhere, must be gentle!
    some stiction, esp when brand-new
    when set soft enough to be plush, blows through it's travel on big hits
    Similar Products Used:various lower-end forks; my fave (and reference) fork is my well-preserved Bomber
    Bike Setup:Mongoose Wing Super
    Bottom Line:I bike the moderate-intensity XC stuff heree in the N Texas area. lots of small hits, roots, rock gardens, very few bigger whacks. This fork, with an oil change, works better than expected in this role. Especially for the price - came on my bike, street price is ~100.

    it's a great entry-level fork for general xc. not very stiff, but ok under my 250lb combined bike&rider load. Preload adjustment works great, i ended up setting it pretty soft to get plushness & full travel on the typical trails. It was hugely over-damped from the factory, and would pack up something fierce on multiple quick hits. Switch to 2.5 wt oil in the one leg (go to website for instructions) was quick & easy, made a world of difference.

    Set-and-forget fork. once set up, quite plush and comfy going over the trails, but will bottom out pretty hard on any hit more than 18" or so. Steering accuracy is OK, a fair amount of flex present, but nothing ridiculous.

    This is a $100 fork, don't expect anything more than you pay for. But for the price point, it's surprisingly comfy, adjustable, and rideable.

    Overall i have to give a 3, since there is much room for improvement. but it scores well in the bang for the cash category.
