The AT fender reinforcement plate reduces stress fatigue where the fender mounts to the brake bridge. It is inspired by an old French design. These were popular on the French constructeur bikes, and some current builders fabricate these plates from scratch for their own fender installations.


The plate is waterjet-cut from aluminum sheet stock. It is then curved so it wraps around a typical fender (fenders vary greatly in their cross-section curvature, so you may have to adjust the curvature by hand). Finally it is polished to a mirror finish. Pre-drilled for M3 mounting bolts and an M5 bridge bolt.At 0.64mm thick, it won't alter the fender line of an existing fender installation.


Comes with two M3 stainless slotted bolts with flat washers, star washers and nuts, and a leather washer for use at the bridge.


Optionally you may spread a dab of silicone or other adhesive between the fender and plate before fastening for added strength.
