Components

Our world-class engineers, state of the art production facilities and the ability to tap into proprietary materials allow us to design and build the best components in the world. Whether looking for new wheels, a better fitting bar or a faster tire, Bontrager is the ultimate upgrade.

Brakes

High-performance wheel systems require high-performance braking power. From innovative lightweight calipers to carbon specific brake pads and everything in between, Bontrager has a select line of brake components to keep your speed in check—because the faster you go, the more speed worthy your brakes need to be.

Forks

Designed to be an integral part of any bicycle frame, Bontrager's trademark forks offer razor sharp steering precision while neutralizing fatigue and trail vibration for a safer, more comfortable and confidence-inspiring ride in any condition, on any surface. The Bontrager line features some of those harder to find options like hybrid and 29er forks.

Handlebars

Bontrager offers handlebars for nearly every type of riding imaginable. Commuters, mountain biker riders and Tour winners alike will be equally impressed with the performance, control, options and comfort found in Bontrager's extensive handlebar collection.

Saddles

Selecting a saddle is arguably the most personal component choice made by any rider. That's why every Bontrager saddle is backed by the Unconditional Comfort Guarantee—so you can be confident in your choice.

Seatposts

Saddle setup is one of the most critical elements in achieving a proper bicycle fit, making a highly adjustable seatpost essential. The unique clamp design found on Bontrager seatposts sets them apart from the competition in both functionality and performance.

Speed

Our goal - to help you, the rider, be faster on your bike. Armed with cutting-edge technologies, world-class engineers and state-of-the-art production facilities, we are able to design products that are faster, lighter and easier to use. Performance-proven by professional athletes and everyday riders, Bontrager is the ultimate upgrade for race day and every day.

Stems

Strong first, light second and often not cheap, Bontrager has never cut corners when it comes to something as important to safety as a stem. But having a safe stem shouldn't mean limited sizing options, that's why Bontrager stems come in a wide variety of lengths and rises. No matter what your style of riding, Bontrager has a stem with the fit, performance, and style you're looking for.

Tires

For over a decade, Bontrager has developed a comprehensive line-up of tires, today producing a selection of tires suitable for just about any condition out on the trail, road or local path. From the puncture-resistant Hard-Case collection to the aerodynamic R4 Aero to a wide range of off-road treads, Bontrager has a tire to handle it all.

Wheels

Next to the bike frame itself, nothing has a bigger impact on your bike's performance than your wheels. From rugged training wheels to featherweight racing wheels, upgrading to a set of Bontrager wheels is a surefire way to save weight, go faster, and improve your bike's handling.
