The 28mm internal rim width improves tyre profile and grip by increasing the contact patch, while also enhancing stability and reducing tyre roll at lower pressures. This makes it especially effective for modern XC tyres in the 2.2–2.4” range.
At the hub, the JB01 rear hub (12x142mm non-boost) features sealed cartridge bearings for longevity and easy maintenance, along with 30 points of engagement (12°) for reliable power transfer on climbs and technical terrain.
The Shimano HG freehub ensures compatibility with a wide range of 8–12 speed Shimano and SRAM (non-XD) cassettes—making it a versatile choice for most drivetrains.
