When you’re gunning for the KOM on the toughest mountain climbs, nothing gives you more of a boost than a light and snappy carbon wheelset. This newcomer in the Cosmic family takes over the venerable Ksyrium Pro Carbon SL Disc. It features a reengineered carbon rim that’s the lightest in its category. Its 32mm airfoil shape slices through wind, and because the rim is made specifically for disc brakes, you’ll have more confidence and control on the descents.
- 32mm deep/28mm wide NACA profile optimized for disc brakes
- Fore Carbon spoke attachment saves 40g and eliminates rim tape (another 30g saved per wheel)
- Patented lightweight aero spokes
- Fore Carbon technology keeps the rim upper bridge solid and makes the rim stiffer
- New Infinity hub plaform: stiff axle, durable bearings and new hub design with optimized lacing and spoke tension
- ID360 freewheel technology for instant power transfer
- No tubes means less friction, better efficiency and grip, a reduced risk of punctures
- New rim bed shape makes it easier to mount and change tires
- Fore Carbon drilling technology doesn’t require the use of rim tape
Occasionally, without notice, manufacturers change product design and/or specifications.
