Boyd’s new lenticular shaped TT wheel fights real-world wind, in disc & rim brake form


[ad_1]

In a time trial, you’re racing against the clock and you need all the speed you can get. That means crafting the most aerodynamic silhouette and making calculated gear choices for big-time gains. For nearly all, this means a solid disc wheel on the rear of your TT set up to combat the wind and convert every watt into forward momentum.

Boyd wheels know a thing or two about wheels and aerodynamics having manufactured everything from gravel, road, and mountain bike wheels. The newest offering to the Boyd wheel line is an updated TT wheel, available in both rim and disc brake configurations.

The new wheel was developed together with aerodynamicist and professional cyclist Chris Uberti. The team put in hours of CFD (Computational Fluid Dynamics) work to create the fastest possible wheel, whether on a disc or rim brake frame.

Lenticular shape for real-world challenges

The new TT wheel from Boyd features a unique lenticular shape that helps the wheel maintain a slippery shape in rotation and differing wind conditions. Boyd performed rounds of CFD testing with rotating wheels to optimize for higher speed riding (20mph+) in wind conditions between 0 and 10 degrees of wind angle (yaw angle).

This scenario represents 70%+ of riding conditions on a very windy TT course and 90%+ of riding conditions under normal wind conditions. The lenticular angled disc wheel is optimized for going fast on real roads with real challenges.

The rim has a slightly conservative 19mm internal width and is tubeless ready from the start. Boyd claims to have made the choice to keep the rim width slightly narrow to maximize the intended tire size: 23-28mm.

Another upgrade is the valve cover, no more stickers to cover holes in the wheel. Boyd updated the new TT wheels to have a simple screw-in body over the valve access point.

The new TT wheel comes in both disc brake and rim brake versions. Each has the same shape, and lenticular angled design. The only difference is the hub and braking surface on the rim brake wheels. The rim brake version employs Boyd’s textured braking surface to give maximum stopping power when needed.

The disc brake wheel uses a center lock Boyd hub, similar to the ones used on the Boyd Podium road wheels. Both wheels are available in Shimano and SRAM XDR freehub body.
