3T Discus 45 l 40 LTD Carbon Ti TLR Clincher Disc Wheelset - 700CThe worlds widest aero wheels, significantly improving the aerodynamics of big road and gravel tires from 35mm WAM to MTB tires. HUGE INNER WIDTH At 29mm, the Discus 45 40 has by far the widest inner width of any (aero) gravel rim. That means less tire flop, so your cornering is more precise as the tire doesnt roll over the rims edge. A big inner width also means you can run a lighter, narrower tire for the same WAM.
