Derailleurs

About

The derailleur is one of the most rider-facing components on any bike — it's what translates a shift input into a gear change, and when it's working well, you stop thinking about it entirely. The RA Cycles derailleurs collection covers the full range of modern shifting hardware: rear and front derailleurs from SRAM, Shimano, and Campagnolo across road, gravel, and mountain disciplines, plus derailleur hangers, adapters, and accessories for custom builds and replacements. At the top end, CeramicSpeed OSPW systems replace a standard derailleur's pulley cage with titanium-axled, oversized ceramic-bearing pulleys — a meaningful friction reduction for riders chasing every watt. Whether you're building a new drivetrain, upgrading an existing one, or sourcing a single replacement part, this collection has the hardware.
