MS FH Body w/12x142/148/157 End Cap Ceramic EXP

DT Swiss MS FH Body w/12x142/148/157 End Cap Ceramic EXP is an OEM replacement freehub body assembly designed to restore reliable cassette fit and crisp drivetrain function on compatible DT Swiss rear hubs using the Ratchet EXP system. It includes end-cap hardware for common 12mm thru-axle rear standards (142, 148 Boost, and 157 Super Boost), making it a practical way to refresh a worn driver or complete an axle standard change without replacing the entire hub.

• Genuine Ratchet EXP replacement - Correct fit and function for DT Swiss Ratchet EXP hubs; Ratchet EXP and legacy ratchet freehub bodies are not interchangeable
• 12mm thru-axle end-cap coverage - Supports 12x142, 12x148 (Boost), and 12x157 (Super Boost) rear spacing for streamlined axle conversion and wheel reconfiguration
• Driver standard matters - Built around the specific freehub spline standard selected; correct matching ensures proper cassette engagement and avoids fit issues
• HG compatibility notes (for HG versions) - HG 8–11sp is not compatible with HG 11-speed road cassettes; HG 11sp road fits Shimano/SRAM 11-speed road HG cassettes and also works with Shimano/SRAM 8–10-speed cassettes when used with the appropriate spacer
• Service-ready replacement - Direct replacement format simplifies routine hub service when the freehub body is worn, contaminated, or being updated for a new drivetrain setup
