The Kink Brace cranks features a traditional 3 piece design with left and right side sprocket bosses with a 22mm hollow spindle. The custom spindle bolts feature both 3/8” ratchet and 6mm Allen key broaches. The crank arms feature oval tapered tubing for a sleek look and a stiff feel, and the large radiuses on the spindle bosses make these cranks more ankle friendly.
