Stems

Save watts, ride faster

This aero upgrade cleans up your cockpit by securely storing cables for a refined look and free speed. The Aeolus RSL bar/stem combo is proven in the wind tunnel to save 7 watts, making it 10% faster than its predecessor. It's light, fast, easy to install, and Blendr-compatible for seamless integration of your light or Garmin.

Features
- OCLV Carbon construction is ultra-light, compliant, and durable
- Integrated bar/stem design improves aerodynamics and saves weight
- Proven in the wind tunnel to save 7 watts, making it 10% faster than its predecessor
- Integrated cable management system held secure with M4 hex bolt, 5Nm torque
- Variable Radius Compact (VR-C) design allows longer reach and drop
- Includes Blendr mono and duo bases with mounts for Ion light and Garmin computer
- Approved for use with carbon or alloy steerer

Positioned for power

The Trek Aero RSL Road Integrated Handlebar/Stem is built upon our Race Fit, with a shorter reach and hoods that are 3cm narrower than the drops. This moves you into a more comfortable ergonomic riding position that greatly reduces rider drag for an extra aerodynamic advantage.

A 6-degree flare allows for ample wrist clearance and control, so you don't lose any power or comfort in explosive sprinting moments. Plus, riders get the weight-saving and aerodynamic advantage of a single-piece bar combined with stem.

Product details
- OCLV Carbon construction is ultra-light, compliant, and durable
- 7-degrees of ergonomic backsweep reduces rider drag for extra aerodynamic speed and comfort
- Hoods measure 3cm narrower than drops
- 6-degree flare provides ample wrist clearance for sprinting
- Aero RSL Pro Blendr mount and Barstem Top Cover sold separately
- Electronic shift compatibility only
- Compatible with Madone Gen 8, Checkmate SLR, & Checkpoint SL Gen 3 (requires additional parts)
- Race Fit puts riders into a more comfortable, ergonomic riding position

There’s something about 7/8" (aka 22.2mm) handlebars that seem to attract the most abusive riders out there, so we’ve taken our popular Boxcar stem and beefed it up even further! We already use 2024 alloy for all of our boxcar stems, as it has a higher fatigue and yield strength than 6061. We made sure the clamp was extra thick on this version and even added 2 more high-strength stainless faceplate screws. Is it overkill? Definitely. You’d have to run this thing over in a tank to damage it, but we’re pretty sure this will be the last 7/8" stem you’ll ever have to buy. - Machined in sunny Chico, California - 6 bolt faceplate (stainless T25 bolts) - 7/8" (22.2mm) bar clamp - Stack height: 36mm - 180g
