Bontrager Aeolus RSL TLR Road Tire

A light and fast race tire designed for pure speed on the tarmac

RSL TLR Construction: 320tpi cotton casing with sub-tread puncture protection

Race Dual-Compound: fast rolling center and grippy shoulder

Tubeless Ready (TLR) for easy tubeless setup and puncture protection

Cotton casing conforms to surfaces better through flexible fibers for a smoother, faster, grippier tire

Firm smooth center tread is key to straight line speed and softer shoulders stick to corners with confidence

Compatible with hooked and hookless type rims (max pressures vary by size and type)

The Aeolus RSL TLR is built for riders who want the fastest, most efficient road tire in Bontrager's lineup — racers, serious training riders, and anyone running a performance road or triathlon setup where rolling resistance is a genuine priority. It's equally well suited to those upgrading from a heavier training tire for the season's key events, or riders building out a tubeless system on a race-ready wheel set. Our team at Fresh Air will help you find the right size and confirm rim compatibility in-store at both Kelowna locations. Stop by to work with one of our experienced staff members, or call 250-763-3425.

Selecting the right width for a race tire involves balancing aerodynamics, rider weight, road surface, and rim inner width — and with the Aeolus RSL available in four sizes, there's a meaningful difference between them. Our staff can help you dial in the right width for your wheels and riding goals, walk you through tubeless setup if you're converting, and confirm max pressure recommendations for your specific rim type. Whether you're running hooked or hookless rims, we'll make sure you leave with the right setup.

Q1: How do I choose the right width Aeolus RSL TLR for my bike? The Aeolus RSL TLR comes in 26, 28, 30, and 32mm widths. The best choice depends on your rim's inner width, your frame clearance, and your riding priorities. A 26 or 28mm suits narrow-rimmed race wheels and riders prioritising aerodynamics; 30 and 32mm widths pair better with wider modern rims and offer more comfort and grip over longer or rougher roads. As a general rule, a tire mounted on a rim should measure slightly wider than the rim's inner width for optimal shape and performance. Our team can help you confirm the right fit for your wheels in-store.

Q2: Is the Aeolus RSL TLR compatible with hookless rims? The Aeolus RSL TLR is a tubeless-ready clincher with a folding bead and is designed to work as both a TLR and standard clincher. Hookless rim compatibility should be confirmed against your specific rim manufacturer's guidelines, as maximum pressures and approved tire combinations vary. If you're unsure whether your wheels are hookless or what pressure limits apply to your setup, stop in and our team will help you work through it at either Fresh Air location.

Q3: What does 320 TPI mean, and why does it matter for a road tire? TPI stands for threads per inch — it describes the density of the tire's casing fabric. A higher TPI means finer, more closely woven threads, which produces a suppler, more flexible casing that conforms better to the road surface. This translates directly to lower rolling resistance and a smoother, more compliant ride feel. At 320 TPI, the Aeolus RSL uses one of the highest casing densities available in road tires, placing it firmly in race-tier territory alongside cotton-cased handmade tires. For comparison, most training and all-road tires run 60–120 TPI.
