Parts Shimano XTR FH-M9111 Rear Hub

The new Shimano XTR hubs were developed to meet the demands of the worlds best MTB riders and racers.  When searching for innovation and speed Shimano left no stone unturned or untested.  An example of this is the new Micro Spline freehub which was developed in collaboration with DT Swiss.  This new Micro Spline freehub allowed Shimano to develop cassettes with a huge gear range.  All the way from the tiny 10T cog to the enormous 51T cog.  The Micro  Spline freehub also runs very quite with their new pulley freewheel system.  They have moved away from traditional pawls to a new system that allows a very low 7.0 ° engagement.  This reduced travel between the freehubs ‘pick up points’ is perfect for racers looking for that edge.  Shimano has stayed true to their roots with their tried and tested cup and cone bearing system.  Polished and hardened steel bearing shells and stainless steel balls make for fast rolling hubs. Protect these behind Labyrinth and Contact seals and you have a hub with a long service life that will stand up to today’s MTB rigors.
