While not the lightest cranks on the market, these are strong and reliable. The cranks are stiff. Easy to install. The narrow-wide chainring is smooth and worry free(No dropped chains). Great price point.
If the best bike parts are the parts you forget you have on the bike, this X1 crankset is one of the best components on the market. Superb pedaling efficiency, maximum quality, zero chain drop (in 6 months), and smoother than your mom's Cadillac. From rock slams to stupidly-planned jungle marches, the forgot-you-own-it phenom has simplified my life. I don't worry about breaking a crank arm, because I don't think about my cranks anymore. Endless worry has ended, and these cranks are the reason why.
