From gravel races to epic adventures on variable terrain, this superlight carbon wheel combines speed, agility and durability to help you crank out more miles with smooth efficiency. The Allroad Pro Carbon SL features cutting-edge technologies, blending our proven expertise in building race-winning road rims with the lightweight strength and durability of our MTB wheels. The full carbon rims have a 23mm inner rim width and feature our UST tubeless technology. This gives them a super dynamic feel and the added puncture resistance of tubeless tires. The rims are compatible with a wide range of tires (28mm to 62mm), giving you the freedom to choose based on the terrain you are riding. Lightweight double-butted steel spokes produce just enough vertical compliance to take the edge off rough roads. The wheels feature 24 spokes front and rear for optimized distribution of braking forces. It's everything you need to tackle rough roads, gravel or dirt with maximum speed and control. The Instant Drive 360 freewheel coupled with Mavic's automatic bearing preload adjustment (QRM Auto) delivers fast engagement and durability. Engineered specifically for disc brakes, it's compatible with a 12x100 axle up front, and 12x142 rear, and can convert to Quick Release with supplied adapters. The front hub can also be converted to 15mm with an optional axle. It's available for Shimano and Sram XD-Road cassettes and can convert to Campagnolo with an optional driver body. For Center Lock disc rotors only.
