Component manufacturer Tune announces extensive changes to its product portfolio. The KillHill/ClimbHill and Princess/Prince hub models are being removed from the range. The Yokto, Nano and Micro models are new to the range. All existing wheels will be available with the new hubs in future. The technical improvements include a new freehub system with optimized tooth ring geometry and more engagement points, improved seals and a new design. In addition, there is no longer any need to adjust the axial play using shims. The products should be available from May.
