The Roval CLX 32 rear wheel is one of the lightest wheels for tubed tires. You won't have to compromise on performance, as our meticulous development, backed by extensive practical and lab tests, allows us to create a 740 g lightweight wheel that is robust enough for cross-racing use while being light enough for quick acceleration and noticeable energy savings uphill. The low inertia and high stiffness make your bike agile and precise. Furthermore, we have ensured that this wheel performs aerodynamically very well despite its lower rim profile. The CLX 32 was developed using CFD simulations in conjunction with 26 mm wide tires. The result of this approach, for which we could utilize our own wind tunnel, is a wheel with better aerodynamic values than many high-profile wheels. The CLX 32 is completed with aero hubs in a disc design, high-quality DT internals, low-friction CeramicSpeed bearings, and DT Aerolite spokes.
