During the 2019 race season we saw 'mullet' wheel sizes becoming popular amongst some of the fastest riders in the world.  Synthesis wheel system is already tuned to be front and rear specific but could combining with a larger front wheel and smaller rear be the ultimate combination, quite possibly!

This wheelset comes with a 29" wheel upfront and a 27.5" wheel on the rear, equipped with the Industry 9 Hydra hub.



  • Mountain bike's first tuned carbon wheel system for downhill.
