Mavic Allroad SL Road Plus wheels feature a widened 650B rim, ensuring speed, control and dynamic handling when tackling the most difficult terrain, whether it´s road, cobble, gravel or dirt. The wider 650B rims allow you to fit wider tyres at high volume, while maintaining the responsiveness of a conventional road bike. The extra 5 cm of wheel circumference improves traction and comfort, reduces the risk of pinching punctures and allows you to adjust tyre pressure to suit the terrain.The Allroad SL Road Plus has a rim weighing just 440 grams and patented lightweight aero spokes. The QRM Auto self-adjusting freewheel body requires no adjustment and guarantees great durability. No need for a rim base thanks to the Fore drilling, saving 30g per wheel. Fore technology increases the strength of the upper bridge of the rim, reinforcing its lateral stiffness.Specifications:Rims:- Material: Maxtal- Height: 22 mm- Tyre: UST Tubeless and inner tube- Internal width: 25 mm- ETRTO: 25-584Spokes:- Material: Steel- Shape: Straight, aerodynamic elliptical, tapered- Number: 24 (front/rear)Hubs:- Front and rear body: Aluminium- Axle material: Aluminium- Instant Drive 360- QRM Auto- Freewheel: Shimano/SRAM, Campagnolo and XD-R convertible with optional freewheel bodies- Braking: Disc, Center Lock- Front axle : Through axle 12x100 mm, convertible quick lock with the supplied adapters.
