Aeolus RSL
Aeolus, the god of wind and nemesis of all road cyclists, has been doling out performance-inhibiting wind for centuries. Lucky for you, we’ve spent the last 25 years engineering ways to outsmart him with our proven Aeolus wheels, saddles, handlebars, and tires.
Race day, every day
Aeolus RSL is a race-ready road tire that delivers a serious +3.7 watt savings* in rolling resistance, giving you a massive boost of free speed. *Versus the R3 TLR.
Tires 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 320tpi cotton casing with more flexible fibers 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 setup. A sub-tread breaker belt directly under the tread provides an additional later of protection from road debris.
Road tire pressure recommendation
Find rider weight and match it with your tire width to find a recommended tire pressure. It can be helpful to set the front tire up at a slightly lower pressure. If your tires feel too soft or too firm, add or remove pressure to dial in your tire pressure for your surface. The recommended pressures are guidelines. Do not exceed the maximum rated pressure indicated on the sidewall or rim. Follow the rim manufacturer's recommended pressure ranges for your rim width/tire combination.
Sealant recommendation by tire size
Follow the sealant recommendation for your tire size to get your tires set up tubeless and ready to ride.

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.
