In the race against the clock, Bontrager's Race Lite Clip-On Aerobars S-Bend give you the advantage you need. Adjustable arm rests and extensions allow you to dial in your profile position so you can comfortably stay in a wind-slicing tuck. And the internal cable routing keeps everything out of the wind, nice and neat.

The OCLV Carbon Mono Bar Extension delivers an even more aerodynamic leading edge to Trek's drag-defying Speed Concept (Gen 2). These straight and S-Bend extensions are designed to be cut to length and have internal routing for standard or Di2 cables. - Designed specifically for 2014 Speed Concept - OCLV Carbon fiber mono extensions - Straight and S-Bend extensions are designed to be cut to length - Internally-routed for Di2 and standard cables - Designed to accept 22.2mm standard extensions
