The SRAM Conversion Caps for Roam 60/50 and Rail 50 wheels are designed to give your wheelset maximum versatility across different axle standards. These precision-machined end caps allow you to adapt compatible SRAM wheels to various hub and axle configurations commonly used on modern mountain bikes. Whether you are updating an older frame, swapping wheels between bikes, or future-proofing your setup, these conversion caps provide a clean, secure interface without the need for a completely new wheel or hub.
Engineered to match SRAM’s Roam and Rail series hubs, the caps install quickly and reliably, typically without special tools. Their robust construction is made to withstand the demands of off-road riding, from trail and all-mountain to light enduro use. By ensuring proper fit and alignment of your hub in the fork or frame, they help maintain smooth bearing performance and consistent handling. Ideal for riders who frequently change components or travel with multiple bikes, SRAM Conversion Caps offer a simple, cost-effective way to keep your wheelset compatible with a wide range of 9/10-speed MTB drivetrains and axle standards.
