- Great value forged cranks from Jitsie. - Constructed from forged 7075 T6 aluminum for optimal stiffness. - Material removed from the back of the cranks saves weight while maintaining strength in key areas. - 1.37" x 24tpi threaded section suitable for all trials freewheels or threaded cogs. - Matte anodized black finish with Jitsie logos. - Compatible with all ISIS bottom brackets. - Available in 160mm, 165mm, 170mm, and 175mm lengths. Please note that the minimum required thread contact between crank arm and sprocket/freewheel is 9mm, and a 1.37" sprocket/freewheel with maximum internal thread diameter 33.80mm (NOT 1.375") must be used. Failure to adhere to this instruction will damage the cranks threads and this is not covered under warranty.
