    When it comes to bang for the buck, Shimano's Zee components — like this 83mm bottom bracket-compatible Zee FC-M645 Crankset — are hard to beat. Thick-walled aluminum construction with a reinforced steel axle ensures flex and failure are absent from gravity-fueled runs.

    These two-piece cranks are 10-speed only and come with a 36t chainring. For added durability, Shimano gives the Zee cranks steel pedal inserts. The drive-side arm has a 104mm BCD, and it uses alloy chainring bolts. Shimano's Zee FC-M645 does not include a bottom bracket, and it comes in three lengths: 165, 170, and 175mm.
