Cosmic SLR 45

The drive to reduce weight may be a universal obsession for every cyclist, but not every gram is created equal. A rotating mass requires additional kinetic energy to accelerate, meaning that rim weight directly correlates with snappy accelerations and out-of-the-saddle kicks. While tubeless wheels roll faster, they come with added weight and the hassle of a rim tape. In the quest for a lightweight solution with no compromise on rigidity, our engineers went back to the drawing board and came up with our new Cosmic SLR45 wheelset.

Our Fore Carbon Technology lies at the heart of the Cosmic SLR45 design. It’s the result of years of research and combines low weight and improved tubeless assembly with increased rigidity and ease of repair. 10% lighter and stronger than traditional wheel designs, our Fore Carbon Technology incorporates spokes that fit directly into a co-molded metallic insert that avoids the need to drill the upper rim bridge. This negates the need for rim tape, makes for easy repairs, and saves an additional 30g per rim.

Accelerate and climb faster, hold higher speeds

New rim laminate and Fore Carbon spoke attachment saves 40g and eliminates rim tape (another 30g saved per wheel)
45mm deep/26mm wide NACA rim profile optimized for disc brakes
Patented lightweight aero spokes

Stiffer wheel for improved power transfer

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 optimizes lacing and spokes tension
ID360 freewheel technology for instant power transfer

Improved UST Road delivers more speed, comfort and control in an easy to use tubeless system

No tubes means less friction, better efficiency and grip, and 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
