Shimano ZEE M640 Crankset with Bottom Bracket

Stiffness was put at a premium so if you need to stomp on the pedals to get up to speed quickly or if you’re a Clydesdale who punishes lesser cranksets ZEE has your back. It’s 10-speed compatible and is equipped with a 36-tooth chainring. The bottom bracket is included too.

• Reinforced steel axle with 30% greater stiffness compared to Trail designated crank options
• Steel pedal inserts
• Thick wall aluminum construction
