3T Discus 45 l 40 LTD Carbon Ti TLR Clincher Disc Wheelset - 700C
The worldâs widest aero wheels, significantly improving the aerodynamics of big road and gravel tires from 35mm WAM to MTB tires.Â
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 doesnât roll over the rimâs edge. A big inner width also means you can run a lighter, narrower tire for the same WAM.
HOOKED ON SAFETY
Hookless designs save a few grams and are a good choice for low-pressure applications (such as our 650b DiscusPlus wheels). But at higher pressure, hooked rims provide additional safety. Yes, it make manufacturer more complicated and expensive, but itâs the correct engineering solution.
SAFETY RIDGE
With tubeless tires, rolling resistance is lower and flats are very rare. But when you do flat your road or gravel tire, a safety ridge keeps the tire on the rim for safety and to avoid damage (they're often skipped to save some weight & make manufacturing easier but again, we relish the challenge).
CARBON-TI HUBS
Carbon-Ti makes some of the lightest and most sophisticated hubs in the bike industry, right here in Italy. Weâve used them for a long time on our own wheels and decided that with the Discus 45 | 40 LTD being the ultimate wheels, they deserved the ultimate hubs.
SEALANT-RESISTANT
You may have heard of wheels destroyed by aggressive sealant. Thatâs why we use chrome-plated brass nipples (much more durable than alloy) with stainless steel washers & spokes. For best results, we recommend avoiding alkaline sealants with ammonia or sodium hydroxide.
