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.

Durable, reinforced crankset and a great price.
What level is ZEE in comparison to SLX, XT, and XTR?
I'd compare it to SLX. In terms of price, it's actually just a tiny bit cheaper than SLX. Essentially, it is Shimano's answer to an affordable version of their Saint DH group. Performance wise, it can take some major abuse and keep on kickin'
