The Kink Brace Cranks are a traditional 3-piece design, highly reliable with convenient modern features. 100% 4130 chromoly steel tubing is strengthened by the TruTherm post weld heat-treatment process resulting in truly durable crank arms while the hollow 22mm spindle reduces weight without sacrificing strength. The oval tubing used on the arms gives them a real sleek look while increasing their rigidity. Custom spindle bolts feature both 3/8" and 6mm allen key broaches so installation is super easy with whatever tools you have around. Left and right sprocket bosses let the Brace Cranks be run as either RHD or LHD. ###section### Product Specs Crank Type: 3-Piece Drive Type: Bolt Drive Spindle Diameter: 22mm Drive Side: Left & Right Compatible Includes BB Bearings: No Weight: 949g (33.5oz) ###shogun-image-section### Colour: ED Black, Chrome; Size: 165mm, 160mm, 170mm, 175mm
