In events where it's you against the clock, every aero advantage you can gain will help you place better. A disc wheel on the back of the bike is the most aerodynamic option you can have. With a solid lenticular shape, the flows over the wheel smoother than any spoked wheel, propelling you through the air faster, and shaving time of your next time trial or triathlon.
The rim brake version of the disc wheel featues a tubeless rime bed with a 19mm internal width, perfect for the 25mm to 28mm tires being used in these events. Developed using CFD analysis over dozens of possible wheel shapes, the lenticular shape is optimized for real world wind conditions.
We have all been there, going as hard as you can in a time trial and missing out by a couple of seconds. You start to wonder where you could have made up those few seconds. Don't let your wheel choice be where that time was lost.
