    Strengths:    20mm rear end!!stifest and strongest I've ever had!!
    It's tough as F*ck!!


    Weaknesses:    Mech hanger is non replaceble.ripped the threads twice with a faulty mech,it only costs $30 to fix.

    Bottom Line:   
    This is one of the strongest bikes i've ever riden, the geometry is really good for tight tracks, it pedles really well and it's light!!I've been riding it for over a year now and only problem was the mech hanger the rest of the bike is amaizing.and the ajustble top tube length really helps make the bike easy to set up for demanding track.So any one who wants a light strong and durable bike go for this one!!but it is a bit pricey at £2500 for the frame band new.

    Strengths:    20mm rear hub, well balanced, smooth suspension design, fun bike to ride.

    Weaknesses:    a bit on the tall side, and the derailer hanger is not replaceable. Hard to find customer service. I had to email the UK for help and I got a reply writen in broken english.

    Bottom Line:   
    super fun dh rig that is built to last and will take a nasty beating and keep on eating (bumps and jumps and stuff)
