What are the benefits of cotton construction?
Cotton is thinner thus is lighter weight and more flexible. A more flexible tire, or in other words a more supple tire, conforms to the road better and in turn is smoother, faster, and grippier.
Bontrager Aeolus RSL Tires FAQ
FAQ
What is the Race Dual Compound?
Race Dual-Compound uses firmer rubber in the center tread to carry straight line speed and a softer, grippier shoulder for cornering confidence.
Is it tubeless compatible?
Yes!
Do they require any different setup procedure?
You can follow the normal procedure for tubeless setup, however it is worth noting that with cotton constructions you may see a small amount of sealant show around the sidewalls (only upon initial setup). This should only last a few moments, then simply wipe the excess away. You may also experience a larger drop in pressure overnight, but this will normalize after the initial setup.
Is there puncture protection too?
Yes, Aeolus RSL has a layer of sub-tread puncture protection directly under the center.
What sizes are available?
700c in 26, 28, 30, & 32mm options are available
Will there be a tubular version?
No, Aeolus RSL will be clincher only.
Can I mount them on a hookless rim?
Yes, however max pressures are reduced on hookless rims. Exact pressure limits vary by width, so follow what is printed on the tire sidewall.

Yes, Madone Gen 8 will be spec'd with the new and fastest Bontrager tire—Aeolus RSL!
