Wider is faster and more Aero. Also offers a better ride quality and control for the rider. 

3T combine the best of all worlds with the C45 Wide. Light, wide and very aero these wheels feel fast and light and offer the rider the utmost comfort 

The Discus C45 WIDE is the fastest wheel at this rim depth; in fact it tests as fast as other 60mm deep rims. So you have the advantages of a shallower rim, like ease of handling in crosswinds, and the speed of a deeper rim. The C45 WIDE achieves this with its unique NoseTail design. By definition rim design is a compromise, because it whatever shape is aerodynamic on the front half doesn’t work so well 180 degrees later when it’s backwards.

The NoseTail shape developed by the legendary Dave Kennedy (an aerodynamics professional for over 50(!) years) and 3T’s Head of Design Gerard Vroomen actually sacrifices some performance on the front half of the wheel in favor of working better on the back half. Not only do the two effects cancel each other out, but the resulting shape also requires less rim depth and better guides the airflow from the rear of the front wheel onto the downtube.

    Fat Aero Wheels

    Posted by Kai Serrano [Baja Trout] on 21st Oct 2019

    Got these for higher speed road riding on the 3T Exploro. I have the stock 650B wheels with 2.2 in Race kings for hardcore dirt. The Discus 45/32s have a wide internal width of 25mms which should work well with 28mm road tires up to about 40mm gravel tires. The Aero advantage is apparent and increases at higher speeds. The wind buffeting is more than I expected but getting used to it. Still hit 50mph without touching the brakes!
