Brace cranks are a traditional 3 piece design that are highly reliable w/ convenient modern features. Left & right side sprocket bosses make these cranks compatible w/ left & right side drive, & the 22mm hollow spindle is super strong & fits all modern sprockets. The custom spindle bolts feature both 3/8” ratchet & 6mm allen key broaches, so installation is super easy w/ whatever tools you have around. Oval tapered tubing gives the cranks a sleek look & a stiff feel, & the large radiuses on the spindle bosses make these cranks more ankle friendly. Fully wrapped spindle & pedal bosses paired w/ precision welds, make the Kink Brace cranks a pair that will last.
