SHIMANO XTR rear hub FH-M9111-BS Straightpull for 12x148 mm BOOST thru axle | Freewheel 12-speed Shimano Micro Spline
The new XTR hubs were developed for the highest demands in the MTB sector and form the spearhead of the Shimano off-road program. As is typical for Shimano, they assume the pioneering role in the development and implementation of new groundbreaking technologies.
The Micro Spline freewheel was developed in cooperation with DT Swiss, which enables Shimano to use cassettes with enormous bandwidths and a small 10-tooth sprocket. At the same time, the freewheel principle was changed from pawls to a toothed disc freewheel. Due to the very fine toothing, the distance between the locking points shrinks to just 7.0°. The idle travel when paddling is reduced immensely and always allows you the best possible start, whether in the race or on the trail.
The durable and robust bearing the hub has remained - proven cone bearings with hardened and polished steel bearing shells and stainless steel balls. In conjunction with the labyrinth and contact seals, an excellent service life and the well-known silky-smooth running of the hub are achieved.
