A new dimension in speed
By completely rethinking our design process for Aeolus RSL, we moved way beyond marginal gains. Enabling 3D CFD models in our iterative feedback loop and incorporating more variables that affect speed, we were able to better replicate real-world conditions and make wheels that aren’t just faster but represent a step-change in speed.
The faster you
Aeolus RSL wheels aren’t just faster, they also make you more efficient with less wasted energy. Plus, they offer more stability and more tyre compliance means you can focus on what matters most: being the fastest you.
Wider is faster
Aeolus RSL’s 23 mm inner width provides a better aerodynamic connection with tyres and allows them to roll faster. This design also lets you run lower tyre pressures for a smoother, faster and less-fatiguing ride.
Faster with fewer watts
Aerodynamically faster rim shapes and a wheel/tyre profile proven to reduce rolling resistance add up to major watt-savings. For a rider like Trek-Segafredo's Mads Pedersen, Aeolus RSL can save 34 watts in a sprint finish over previous Aeolus wheels of similar depth.
Race-calibre carbon
RSL-level OCLV Carbon is the lightest and strongest available, and it lets us create the fastest rim shapes we possibly can.
Tubeless Ready (TLR)
Easily set your wheel set up tubeless with Bontrager TLR rim strips, or use a rim tape system for the lightest set-up possible.
Move over, tubulars! This is the fastest wheel and tyre system available, and it’s exactly what’s raced by Trek-Segafredo to give them an edge over the competition
DT with Ratchet EXP hubs
The all-new lighter-weight Ratchet EXP freehubs are built with proven DT Swiss 240s internals for consistent engagement and a smooth, fast-rolling feel.
