Bontrager Aeolus RSL 37 TLR Disc Road Wheel

Bontrager Aeolus RSL 37 TLR Disc Road Wheel

Model 598981

Faster. Lighter. More stable. The ultralight Aeolus RSL 37 is the ultimate carbon road wheel for climbs, crits, and classics. RSL-level OCLV Carbon is lighter and stronger, allowing for a faster, more stable 37mm rim profile that is lighter than shallower wheels and faster than deeper wheels. Ultralight hubs with DT Swiss 240s internals and a Ratchet EXP 36-freehub keep everything rolling smooth.

All Bontrager carbon wheels are warrantied for life for the original purchaser and come with the added protection of Carbon Care. If you damage your wheels while riding in the first two years of ownership, we'll replace them. It’s that easy.

RSL-level OCLV Carbon is the lightest and strongest available, and it lets us create the fastest rim shapes we possibly can.

The lightest carbon aero road wheel we’ve ever made. At 1325g, Aeolus RSL 37 wheels are 55g lighter than their predecessor. And they’re 30% deeper and over 15% faster.

Fast, light, stable—the all-new rim shape delivers the ideal trifecta without adding weight or compromising stability.

The all-new lighter-weight Ratchet EXP freehubs are built with proven DT Swiss 240s internals for consistent engagement and a smooth, fast-rolling feel.

Easily set your wheelset up tubeless with Bontrager TLR rim strips or use a rim tape system for the lightest setup possible.

Carbon wheels can lighten your ride and improve your performance—and when you ride Bontrager, your investment is protected. All Bontrager carbon wheels are backed by a lifetime warranty for the original owner.
