Derailleur hangers are the most frequently needed frame-specific part in cycling — they’re designed as a sacrificial component, built to break on a crash or impact before the derailleur or frame does. Because every manufacturer designs their dropout geometry differently, hangers are not interchangeable across brands or even model years. The same applies to proprietary seatposts: many high-end frames use non-standard tube diameters, shapes, or offset specs that require the exact post designed for that platform. Rear shocks are similarly frame-dependent — trunnion vs. standard mounting, eye-to-eye length, and stroke measurement must all match the frame’s spec precisely or the shock simply won’t install.

This collection brings together 185+ frame-specific parts across several categories. FOX Float X and DHX Factory rear shocks cover suspension replacements and upgrades for compatible full-suspension frames. Pinarello’s proprietary seatposts span the Dogma F, F8, F10, and F12 platforms in multiple setback and finish options. Derailleur hangers cover dozens of brands including Pinarello, Scott, Colnago, Cervelo, and more. If the specific part you need isn’t in the catalog, the RA Cycles team can assist with sourcing.
