Mavic Ksyrium SL Rear 2025

Ksyrium has always represented the best of aluminum wheel technology. Following in the footsteps of the venerable Ksyrium Elite and Ksyrium Pro, the all-new Mavic Ksyrium SL takes it to the next level. It’s the perfect all-rounder for those seeking a wheel that delivers reliable everyday performance on the road.

This new wheel is lightweight (100g lighter than the former Ksyrium Elite despite its wider rim) and durable as ever thanks to Mavic patented ISM4D technology. This manufacturing process removes all excess material between each spoke hole while keeping the rim wall thick enough where spoke tension and stress is the highest. Those rims are made in France, in Mavic aluminum rim factory.
The double-butted spokes further reduce weight while making the wheel more responsive. These spokes also have a patented elliptical shape that can save 5 watts for added efficiency.

Stiffness is optimized using Fore technology. The upper bridge is not drilled, so it remains strong and rigid and doesn’t require the use of a rim tape (another 30g saved per rim). The rim bed’s new shape makes it easier than ever to mount and remove tires, and our UST Tubeless technology improves rolling resistance and grip while reducing the risk of punctures. Mavic new Infinity hub platform optimizes stiffness and power transfer with highly controlled spoke tension, while the Instant Drive 360 freewheel coupled with our automatic bearing preload adjustment (QRM Auto) delivers fast engagement and durability.
It's available for Shimano cassettes, and can convert to Campagnolo or SRAM XD-Road with optional driver bodies..
