Aeolus RSL
Aeolus, the god of wind and nemesis of all road cyclists, has been doling out performance-inhibiting wind for centuries. Luckily for you, we’ve spent the last 25 years engineering ways to outsmart him with our proven Aeolus wheels, saddles, handlebars and tyres.
Race day, every day
Aeolus RSL is a race-ready road tyre that delivers a serious +3.8-watt saving* in rolling resistance, giving you a massive boost of free speed. *Versus the R3 TLR.
Tyres with a tailwind
The new design cultivates impressive aerodynamic gains, helping you save precious watts that’ll have you feeling like you’re always in a tailwind.
Crafted with cotton
A 320 tpi cotton casing with more flexible fibres offers the comfort and speed by better conforming to road surfaces. The result is a smoother, fast and grippier experience.
Flat-free racing
Ride easy with the confident flat protection of a Tubeless Ready set-up. A sub-tread breaker belt directly under the tread provides an additional layer of protection from road debris.

If for any reason you’re not satisfied with a Bontrager or Trek aftermarket purchase, return the item, along with the original sales receipt to the original place of purchase within 30 days for an exchange or refund. Think of it as a 30-day test ride.
