    Strengths:    Very light. With Crank Bros Ti BB I saved over 100g compaired to XTR

    Weaknesses:    Dont like ISIS BB's, Im 6'2" #200 and when I really stand on them they flex noticably. Stronglite big ring doesnt do good on upshifts.

    Bottom Line:   
    Generally you can get them for less than $200 (compared to the $700 retail). Very light and reliable. Best bang for the $ and one of the lightest cranksets out there. Likely the lightest one I would trust! Well designed. Although b pretty useless for me, the ALS (adjustable length system) has not been a detriment. I suppose if you needed different crank lengths left to right, this would be a great feature. If your thinking about it and you weigh less than #225 go for it! I liked them enough I bought a second set.

    Strengths:    Light, stylin, ALS

    Weaknesses:    Soft chainrings, cost, fragile

    Bottom Line:   
    After two rides, the chainrings had loosened- all of them Loctite took care of it. But the large chainring was all sorts of warped after simply crossing some large logs. No problem bending back with a crescent wrench. At the end of this year's season, one arm failed when the end cap/core separated from the carbon wrap. Bontrager has made good on warranty but I cannot recommend this part due to lack of durability and possible design problem with the internal bonding. Don't buy it unless you hardly ride and like to look good standing next to your tricked out rig.

    Strengths:    Looks nice

    Weaknesses:    Comes loose and splines on aluminum inset in crank get widened and it knocks. Flexy. Easy to scratch the clear coat even withthe gurads. It looks pretty rough after a few weeks.

    Bottom Line:   
    If you get this crank, start off with some thread locker on day one and make sure it is tight. Sexy but flexy.

I did a quick comparison with the Raceface Next LP Riser I had and the difference is pretty noticable. The ne ... Read More »
