Headstock cap with 5mm washer in one. Included with spacer for carbon fork posts. The ideal choice for your road or gravel. The cap has a clean and simple appearance without sharp edges. What's it good for? There are more reasons. It's ideal for carbon fork posts that require the post to overhang the stem. You have a longer fork post and thus more room for possible changes in the seatpost, either for yourself or for selling the bike to another rider later. Precision workmanship, colorful offerings and quality material made in USA is the wolftooth mantra... Weight (cap + screw + hedgehog): 38 g Material: 6061-T6 aluminum Hedgehog height: 28mm Recommended torque for screw: 2-3 Nm with a little Vaseline Made in USA
