Advanced OCLV Carbon Construction

The Aero RSL is manufactured using Trek's premium OCLV Carbon, delivering an exceptional balance of lightweight performance, stiffness and compliance.

Its one-piece integrated design eliminates the additional hardware found in traditional bar and stem combinations, reducing overall weight while improving steering precision under hard acceleration, sprinting and technical cornering.

The result is a cockpit that feels incredibly responsive while maintaining the vibration-damping characteristics needed for long days in the saddle.

Designed to Make You Faster

Every detail of the Aero RSL has been shaped with aerodynamic efficiency in mind.

Built around Trek's Race Fit, the hoods are positioned 30mm narrower than the drops, naturally bringing your upper body into a more aerodynamic riding position without compromising comfort or bike control.

This rider-focused approach helps reduce frontal area, allowing you to maintain speed more efficiently during fast road rides, racing and time spent pushing into headwinds.

Confidence Through Every Sprint and Corner

Performance isn't just about aerodynamics—it's also about confidence when the pace increases.

A carefully engineered 6° flare provides additional wrist clearance during explosive sprints and out-of-the-saddle efforts, while the 7° ergonomic backsweep creates a more natural hand position that reduces pressure on the wrists during long rides.

Together, these features provide:

• Improved rider comfort
• Confident handling at speed
• Better control during technical descents
• Enhanced sprinting stability
• Reduced fatigue over long distances

Whether attacking climbs or sprinting for the finish line, the Aero RSL is designed to keep you comfortable and in complete control.

Seamless Integration for Modern Road Bikes

The Trek Aero RSL has been developed specifically for today's fully integrated performance road bikes.

Compatible with electronic shifting systems, it delivers clean cable integration and a streamlined front end that complements the latest generation of aero race bikes.

It is compatible with:

• Trek Madone Gen 8
• Trek Checkmate SLR
• Trek Checkpoint SL Gen 3 (additional parts required)

Optional Aero RSL Pro Blendr mounts allow compatible accessories such as cycling computers and lights to be mounted neatly without disrupting the cockpit's clean appearance.
