AERO-OPTIMIZED FOR SPEED

Designed to cheat the wind and for hardcore riding, the AR is a dynamic bike willing to go the distance with whatever you can throw its way, whether that's driving the breakaway or positioning yourself for the final sprint. Shimano's impressive Ultegra Di2 groupset, now with 12-speeds, merges with the performance benefits that our aero frame offers. Ready. Set. Go.

Features

PRECISION SHIFTING FROM SHIMANO

Shimano's 12-speed Ultegra Di2 brings crisp shifting and dynamic functionality for performance-oriented riders. Improved ergonomics and a wireless cock-pit improve on Shimano's already impressive groupset in this latest generation.

AERO WHEELSET IS RACE-READY

Reynolds AR58 DB Custom wheels with Continental Grand Prix SL tires offer a wind-cheating aero profile and great ride feel to keep performance front and center. Confidently rip some technical corners and launch yourself into the break in style.

DIAL IN YOUR COCKPIT

The PRO Vibe Aero bar completes the Shimano assortment, ensuring a clean, ergonomic, and race-inspired front end for the AR. Easy to adjust with a separate handlebar and stem, the AR front-end is purpose-built for your riding needs.
