Reinventing the Ksyrium with a wide carbon tubular rim makes the lightest Ksyrium ever
This tubular version of the Ksyrium Pro Carbon SL is the lightest ever member of the Ksyrium family, at just 1190g. Which makes it the best wheel for the fight against gravity on those long climbs – saving power and making you faster in the long run.
Our lightest ever Ksyrium
We created our lightest ever rims using groundbreaking finite element simulation software. Which means, despite their generous width of 23mm they weigh in at just 320g. Low rim weight means lower inertia, thus better dynamics and handling for fast acceleration, agile descents and instant deceleration.
This extreme low weight is delivered by our light double-butted stainless steel spokes and the lightest hub ever produced at Mavic, featuring our new Instant Drive 360 freewheel system.
But designing the best climbing wheel is about more than just low weight. There are four other key elements:
High lateral stiffness
Thanks to the 24 rear spokes and the Isopulse lacing that makes for better spoke tension balance and higher stability, the Ksyrium Pro Carbon SL T delivers plenty of lateral stiffness, while keeping vertical compliance at its best for great overall comfort on long rides and great tyre traction on rough roads.
Best-in-class braking efficiency
At some point on a mountain climb, you’ll need to fly back down to the valley. So we’ve focused on achieving short braking distances in dry or wet conditions. Our exclusive TgMax technology uses heat treatment and surface preparation to deliver this with wet stopping distance 50% shorter than the closest competitor.
You may be pushing your own limits, but you won’t get anywhere near the wheel’s limit. Ksyrium Pro Carbon SL are sturdy, with biffy axles and bearings and solid spokes and rims. Their low weight doesn’t limit their ability to meet our high standards of toughness and reliability.
Yksion Pro Tubular tyres
Ksyrium Pro Carbon SL T comes with our high-end Yksion Pro Tubular. Made of a supple 220 TPI casing, these tyres have a tubeless construction that delivers a super low rolling efficiency and a great ride quality at an impressive weight of just 270g in a generous 25mm section.
The front tyre gets our Griplink tread pattern that’s designed to move water away when cornering for a safe grip in all conditions. The rear tyre offers our Powerlink design that limits the pressure on the ground for minimum rolling resistance, while moving water quickly away for great traction in wet conditions.

Maximum Glass Transition Temperature
TgMAX technology consists in laying up several types of high technology resins, then fixing them using a proprietary heat treatment process to achieve the highest possible resistance to braking heat.
Grip and control
A front tyre, whether a clincher or a tubular, must fully liberate the wheel’s ability to hold the ground and control the bike. Therefore, GripLink tyres are optimized for front use, by offering a superior grip and extra puncture protection.
Low rolling resistance
A rear tyre, whether a clincher or a tubular, must fully liberate the wheel’s ability to transfer power and generate speed. Therefore, PowerLink tyres are optimized for rear wheel use, by minimizing the rolling resistance.
Qualité de Roulements Mavic
Mavic only uses high quality sealed cartridge bearings. On QRM wheels, they feature double sealing (2RS or LLU) together with tight C3 internal clearance.
Optimum energy transfer
The spokes are laced radially on the drive side and crossed 2 on the non drive side to maximise drive side dish, thus providing a better spoke tension balance between left and right flanges.
