The 1,325-gram Aeolus RSL 37 is Bontrager’s lightest aero wheel ever. At 37mm deep, this carbon wheel is lighter than shallower wheels, and as aero as wheels 10mm deeper.
Plus Bontrager is bringing the new rim shape behind this wheel to the Aeolus Pro 37, offering the same aerodynamics for way less. And the Aeolus line is dipping into the unheard of $900 price range with the Elite 35 and Elite 50 wheelsets.
