MT-051F/R BOOST(Center Lock)

PERFORMANCE ARCHITECTURE

One Boost hub platform, engineered for responsive MTB wheel builds.

A straight-pull Center Lock architecture built around 15×110mm front and 12×148mm rear Boost spacing. The MT-051F/R combines AL6061-T6 hub shells with AL7075 axles, end caps, and freehub bodies, supported by a 6-pawl single-tooth engagement system for responsive power transfer. Its 28H drilling, 14G spoke compatibility, HG, Micro Spline, and XD freehub options, plus steel or ceramic bearing configurations, enable the same hub platform to support different drivetrain and wheel-building requirements.
