Cotic Rack Adaptor Bracket for 31.6 Seatpost

This adapter clamps around the seatpost on Cotic's with rack mounts on the dropout, but none on the seatstay. We have designed this to be used on smaller frames where a frame eyelet would give poor, unstable rack geometry. This bracket mounts higher up on the seatpost for a more solid rack mounting and more stable luggage.

Use this adapter to fit a rear rack to your Solaris (2023 onwards), and Cascade Gen 2 (2025 onwards) XS and SML size frames which have dropout eyelets, but no upper mounting point.

Can be used on any bike with a 31-6mm diameter seatpost
