Reserve

RD1 Carbon One Piece Handlebar

What Our Gearhead® Experts Are Saying:

"I installed the Reserve RD1 Handlebar on a dedicated road race build and the cockpit transformation was immediate. Fully internal routing cleaned up the front end completely, and the 75mm reach with 125mm drop put me in a position that felt aggressive without being punishing over long efforts. For a one-piece carbon bar and stem at this weight, the ride quality is genuinely impressive."

A clean cockpit is not just about aesthetics. When cables disappear inside the bar and every surface is optimized for airflow, the front end of the bike stops being a source of drag and starts being part of the engine. The Reserve RD1 Carbon One Piece Handlebar from Reserve Wheels was built with that principle at its core, delivering a fully integrated bar and stem combination that is 29 seconds faster over 40km compared to conventional setups in wind tunnel testing. On a race day where the winning margin is measured in wheel lengths, that kind of advantage is not a footnote.

Full internal cable routing eliminates every external line between the stem and the levers, maximizing the aerodynamic return of the bar profile and keeping the cockpit clean regardless of what drivetrain or brake system is installed beneath it. Built around the Acros ICR headset standard with compatibility for most bikes using a 52mm oversized upper bearing, the RD1 fits a wide range of modern road frames without compromise. The 75mm reach and 125mm drop sit at a position that supports sustained power output on long efforts and confident handling through tight criterium corners alike, while 6 degrees of both stem angle and flare add comfort and control across big days in the saddle. Claimed weight runs from 301g to 341g depending on size, no rider weight limit applies, and a lifetime warranty backs the entire package for the long haul.
