Using a welded aluminium for its robust build, the 30mm-wide rim stands up superbly to the rigours of off-road riding. Turning on a reliable and durable Pro 4 hub, a silky-smooth spin is assured as you roll across the roughest terrains and harshest conditions. Kitted out with a four-pawl, ratchet system for that extra bit of power and pace when required, this dominant MTB wheel comes with disc brake-optimisation and a tubeless-ready profile for unrivalled control and composure on low-rent routes. A bold back wheel for the big-riding MTBer, the Fortus 30 lets you push every ride to the absolute limit. Please Note: The options that mention "Steel" (for example: "29" 148mm Steel") have a steel Shimano type freehub for 9-11 speed MTB cassettes. They are not compatible with SRAM XD cassettes or Shimano MSpline 12-speed.
