X4 : 31.8 & 35mm MOUNTAIN
Since its inception the X4 has been the best combination of strength and weight available. Constructed from one solid piece aircraft grade aluminum we didn’t sacrifice torsional stiffness or strength for a few grams of weight savings. The X4 offers precise steering and tracking for the ultimate rider control, all while executed in an elegant design. So strong, however extremely lightweight, enduro and downhill riders can run Thomson confidently, yet X4 is light enough for cross country and cyclocross.
