Valves / Accessories

Tubeless conversion starts with the right valve — and the right valve depends on your rim depth, your sealant compatibility, and whether you want brass or alloy. RA Cycles’ valves and accessories collection covers 31 products across tubeless valves, valve extenders, and valve tools from Muc-Off, Orange Seal, Stan’s NoTubes, ENVE, SRAM, Zipp, Vittoria, and more.

Valve lengths run from 23mm for shallow rims up through 60mm, 80mm, and 100mm options for deep-section aero wheels. The Muc-Off Big Bore range uses a wider bore for faster inflation and easier sealant injection. Valve extenders from Zipp and Vittoria let you run a standard stem on deeper rims without replacing the valve core. Valve core tools from Park Tool, Feedback Sports, and Stan’s complete the category for anyone setting up or maintaining a tubeless system.

Tubeless Valves at RA Cycles

Tubeless valves are the foundation of any tubeless tire setup. Unlike a presta valve on a tube, a tubeless valve seals directly to the rim bed and becomes the inflation and sealant entry point for the system. Getting the valve right — correct length for your rim depth, compatible thread type, bore size adequate for your sealant — determines how reliably the tubeless system works. A valve that’s too short can’t engage a pump head properly on deep rims. A bore that’s too narrow slows sealant injection and increases the chance of a clog.

Muc-Off leads the catalog with seven products, including the Big Bore Lite (alloy body, wider bore for easier inflation) and the standard V2 in 44mm and 60mm lengths. Orange Seal’s Versa Valve is available in multiple lengths and works with most tubeless-compatible rims. Stan’s NoTubes covers brass and alloy options at multiple lengths, and SRAM’s valve and tape kit bundles everything needed for a first tubeless conversion. ENVE’s valves are sized for their own deep-section rims. Valve core tools from Park Tool (VC-1) and Feedback Sports (Valve Core Tool 2.0) handle setup and maintenance.

For everything else in a tubeless setup, browse sealant, tape, and tubes and the full bike tires catalog. The wheel accessories collection has rim tape and other wheel-related supplies.
