Bags

Speed Box

$9.99 - $34.99

Keep your race-day nutritional supplements close at with Bontrager's Speed Box. Designed to hold your gels, chewables, bars, and other on-the-go energy products, the Speed Box mounts to your top tube quickly, securely, and aerodynamically behind your stem. Available in two sizes, the Speed Box features an easy-to-open mesh top that provides quick access to your supplements while also keeping them securely inside.

Bottles and Cages

Speed Bottle

$12.99 - $69.99

For the rider looking for every speed advantage possible, Bontrager's Speed Bottle with Carbon Cage is simply the fastest bottle and cage combination on the planet. Developed using Computer Fluid Dynamics to slice through the wind, in certain cross wind situations using this bottle and cage combination is actually faster than using no bottle at all.

Never lose a bottle again, thanks to Bontrager's problem solving Race Lite Rear Cage Holder. Designed to hold one or two bottles, the Rear Cage Holder offers multiple angle adjustments and high/low positioning that let's you dial-in just the right position for easy bottle access. Includes two Race Lite Rear Cages.

Aero Race Pack

$21.99 - $44.99

"Stay hydrated without getting out of your aerodynamic tuck with Bontrager's Aero Race Pack. Designed to mount quickly, easily, and cleanly between nearly any width of aerobar, the Aero Race Pack features an innovative fill cap that makes it easy to top-off your bottle without getting off the bike. An integrated computer mount and an insulated bottle cover further add to the versatility and convenience of this triathlon must-have.

Tri Cage

$14.99

The ultimate cage for behind-the-saddle carrying systems, the unique design of Bontrager's Tri Cage won't drop or eject bottles, no matter how rough the road.

Brakes

HCM (High Compression Molded) carbon arms and stainless steel hardware drop the weight of the Speed Limit XXX brake calipers to a wicked-light 220 grams per pair--50 grams lighter than the standard Speed Limit, which is already one of the lightest road caliper sets. Available in a limited run of 500 pair.

Speed Limit

$199.99

One of the lightest calipers on the market, Bontrager's 270g Speed Limit Brakeset features an innovative PowerAmp linkage that provides the leverage ratio of a dual pivot brake with the weight saving of a single pivot design. Wide cross-section arms give maximum stiffness and power for confident, responsive brake feel. Perfect for road or triathlon use.

Sculpted in the wind tunnel, these carbon levers offer unbeatable aerodynamics without sacrificing ergonomics and usability. Unique cable anchor design provides easy installation and a natural progressive brake force feel. The official aero brake lever of the Radio Shack Cycling Team.

Same great shape and unbeatable features as the top-of-the-line Race XXX Lite but with lightweight alloy levers instead of carbon.

Handlebars

Originally developed for and wind tunnel tested with the Discovery Channel team, the full carbon Race XXX Lite Aerobar is one of the lightest and fastest bars available. Fully-adjustable extensions and arm rests make it easy to dial-in the most comfortable aero position possible. Meets UCI's 3:1 aspect ratio for aero bars thus allowed for use on both road and triathlon bikes.

A perfect complement to Bontrager's Race X Lite Clip-On Aerobar, the X Lite Bullhorn uses a high compression molded carbon airfoil wing shape and internal cable routing to slice through the wind.

Optimized in the wind tunnel, Bontrager's Race X Lite Carbon Clip-On Aerobars use a unique clamping mechanism that mounts securely but is gentle on carbon fiber and lightweight aluminum bars. Constructed from high compression molded carbon and lightweight, forged aluminum, the X Lite Aerobar features aerodynamic internal cable routing and fits both oversized 31.8mm and standard 26.0mm bars.

Further refine your aero tuck and achieve a more comfortable position with these extensions specifically designed to work with Bontrager Aerobars.

Like its lighter sibling the RXL Carbon, the RL Clip-On features a unique clamping mechanism that mounts securely but gently on carbon fiber and lightweight aluminum bars. Wind tunnel sculpted for maximum aero efficiency, the aluminum-construction RL uses internal cable routing and ergonomic S-bend extensions to minimize presentation to the wind.

Race Bullhorn

$39.99 - $49.99

This bar is ideally suited for use with a clip-on aerobar or as a standalone handlebar for fixed-gear or city bikes. Single groove design makes brake cable routing less intrusive. Fabricated from custom butted 2014-T6 aluminum and compatible with Aero brake levers.

Handlebar Accessories

Aerobar Parts

$7.99 - $119.99
