Mavic has released their first ever all carbon clincher wheelsets: the aerodynamic 40mm Cosmic Pro Carbon SL C and lightweight 25mm Ksyrium Pro Carbon SL C.
Mavic has long resisted building all carbon wheels, relying on an aluminum insert to dissipate heat long after other manufacturers had gone full carbon. If there are any qualities that Mavic wants to be known for, it is for safety and reliability, so they took the time to make sure that anything they released could be trusted.
As I’m sure you’ve read before, all carbon wheels have a poor reputation for braking performance, and furthermore, carbon wheels have been known to fail when the resin in them breaks down from the heat of extended braking. Mavic, a long time provider of neutral support at cycling events, has witnessed this firsthand. At the 2015 Etape du Tour, Mavic serviced 100 wheels. 52 of those wheels failed and 38 were from Mavic competitors.
Mavic has solved both issues by combining an all new resin (iTGMax) with a laser etching surface treatment technology that ensures a completely flat brake track as well as a maximum heat dispersion.
The laser etched wheels show 20-30% better braking in dry conditions and an amazing 50% improvement in the wet.
The technology is available in two new wheelsets:
Cosmic Pro Carbon SL ($2199, on sale in March(rim) and April (disc))
- Wheelset weight: 1,450 grams
- 40mm wind tunnel tested NACA profile rim
Ksyrium Pro Carbon SL C ($2199, on sale in June)
- Wheelset weight: 1,390
- 25mm rim
Both feature all carbon construction with a one piece rim bed and sidewall construction. Internal widths are 17mm and they have 25mm external width. They are available in both rim brake and road disc versions.
On the Ksyrium Pro Carbon SL C the rim depth is noted as 25mm
When measuring actual rim (25mm) depth, where do you measure from?
Rim depth is the entire depth including the brake track (or what would be the brake track if these were rim brake wheels).
