The Trek Aero RSL integrated cockpit, also sold as the Bontrager Aeolus RSL, is the one-piece bar and stem fitted to Trek's fastest race bikes. It suits riders chasing aero gains and the clean front end that only full integration delivers.

Bar and stem are moulded as a single OCLV carbon unit, which removes the clamp interface and lets Trek shape the whole assembly aerodynamically. Cables and hoses route internally, so there is nothing catching the wind or rattling. The tops are flattened for comfort on long climbs, and the drops flare slightly for control.

Key features

• One-piece OCLV carbon bar and stem

Integrated cockpits are sized as a single unit, so the fit needs to be right before you buy. Talk to us about a bike fit first.
