Profile Design Aluminum Gap Cap
Installing a threadless fork doesn't get any easier. The Profile Design Aluminum Gap Cap has an exclusive 3-wedge design that eliminates the need for a star-fangled nut. The Gap Cap aligns perfectly, no matter what the steerer tube material. Smooth expanding wedges make it easy to transition from a 1" to a 1 1/8" steerer tube and grips tight the first time.
