from seattle wa Date Reviewed: November 20, 2010 Strengths: extremely light! and pretty dang stiff too. excellent finish, anodizing is strong and vibrant(mine are red), very smooth and clean lines and polished surface. i've put 5k miles on em with only the tiniest of scratching and anodizing wear on the edges of arms. the white painted graphics which are overkill for my tastes started rubbing off after 1k miles so i took off the rest with some turpentine and a little elbow grease. looks much, much better now. excellent design with low profile and little heal rub. ceramic bearing bb spins fast and soooo smooth! outer ring is cnc 7075t6, inner two are stamped,also 7075. shift pins and ramps work well, though mine are now only 1x8 setup. outer bolts matching color 7075, inner bolts are very nice titanium. all parts have excellent fit and construction.not sure why others had trouble installing these cranks and BB, as it was the easiest system ive ever wrenched on(and those are many). the only thing mildly difficult was installing pedals because your threading into separate reversible inserts. the inserts are a very nice idea and are well executed, i only use 175mm so far, but its nice to have the option of 170mm arms. i was afraid they might creak, but possibly thanks to liberal ti prep and exact tolerance machining not a sound no matter what. these are way better than any others at this price point! Weaknesses: -would have liked to see 172.5 adapters included, ya gotta buy those separately if ya want them and i kinda do. -the Q factor is a bit on the wide side, i've got fat chainstays and still they have plenty of clearance, but that is not necessary a bad thing... Bottom Line: Expand full review >>Favorite Trail: duthie Duration Product Used: 1 Year Price Paid: $240.00 Purchased At: ebay Similar Products Used: grafton, bullseye, race face, shimano of many many kinds, old mavic, old stronglites, topline(creaky!), vintage coda magic motorcycle(my other favorites) Bike Setup: Carver killer b titanium, loaded with niiice parts

from Indonesia Date Reviewed: November 9, 2010 Strengths: Ultra light! Way cheaper than XTR or X-0 cranks. Weaknesses: Impossibly hard to install. Need a really experienced mechanic to do it. Included bottom bracket is very fast rolling with very little resistance but the bearings must be replaced every 6 months. No big deal. Bottom Line: Expand full review >>Duration Product Used: 1 Year Price Paid: $200.00 Purchased At: authorized dealer Similar Products Used: Shimanos + SRAM cranks Bike Setup: Spark 30 + Titus X 2010
