Triathlon Bikes

Choosing your triathlon bike

Lightweight, streamlined and built for speed, tri bikes are precision-engineered machines that help you go faster and further than ever before on two wheels. When buying a triathlon bike, it needs to be something special to help you sit comfortably in an aerodynamic position during triathlon races and fill you with confidence. We have collated some of the best triathlon bikes at Sigma Sports here. 

TT Bike Fit

We offer professional bike fitting in-store to help you harness the benefits of comfortable, injury-free and more powerful rides on your triathlon bike. The team will set up your bike so that you can harness the advantages of an aero position but still a comfortable riding position.

Whether you're looking at a road bike conversion or a super aggressive fully kitted out tri bike, it's worth paying attention to the details that shape your time in the saddle.

Traithlon Frames

The size, geometry and frame material determine how a tri bike looks and performs.

We provide a world-class selection of carbon fibre tri bikes in sizes that range from XS up to XL frames, including 61cm frames. It's never been easier to find a triathlon bike that suits your height and build.

Triathlon bike brakes

Any triathlon bike needs brake components that are compatible not only with its frame, gearing and wheels but also the demands you place on the bike too.

Reliable Disc Brakes

Many riders ask us if disc or rim brakes are better but the answer for triathlon bikes is disc. For improved safety, most premium tri bikes issued with carbon wheels are those with disc frames. As every minor detail matters with a triathlon bike, some of the top spec models feature intergrated brake calipers to help you maximise your performance in triathlon competitions.

Traithlon Bike Gears

Triathlon bikes feature a very good spec when it comes to gears offering triathletes reliable performance at high speeds. There are tri bikes for every cyclist with Shimano Ultegra di2 and SRAM Force options, while the Trek Speed Concept is featured as part of the Trek Project One offering, perfect for those wanting to make a specific component selection for their new bike.

Shimano 105 Gears

For beginners, there are tri bikes offering fantastic value for money like some Cervelo P-Series models that make use of the reliable Shimano 105 gearing system. This allows triathletes shopping for an aero TT bike, a budget friendly option without compromising on ride quality.

Tri Bike Wheels

No lightweight triathlon bike is complete without a quality pair of wheels and tyres to complete the setup. Most ready-to-ride bikes come with brilliant wheels but if you're building a bike from scratch – or are just particular about your bikes – this is especially important.

Cut Through the Wind with Carbon Wheels

Carbon bike wheels dominate the market. We're proud to supply wheels by leading brands including Scope, Roval and ENVE. You'll always have the option to upgrade your time trial bike into your dream build. Carbon rims are preferred by triathletes as they offer improved aerodynamics, lower overall weight and increased responsiveness on the road.

Bike Builds for Tri

For those customers who want a more versatile or budget friendly option, you can add clip on tri bars to a road bike. Owning only one bike doesn't restrict you from enhancing a road bike to overcome air resistance for triathlon races. Brands such as Profile Design, PRO and Deda Elementi offer excellent aerobars while as outlined above there is a wide choice of wheel upgrades that can be made.

Triathlon Bike Accessories

Beyond this bento boxes can provide the perfect storage option for nutrition or spares, while intergrated hydration systems from brands like X-Lab, Elite and Profile Design will ensure you can cover long distances while remaining hydrated. We also stock a wide range of cycling bags such as top tube bags giving easy access to your essentials when competing in races.

Peroformance Kit to Go With Your Tri Bike

We've also got an extensive triathlon range that features tri helmets, tri clothing, including tri suits, and triathlon shoes so there is no compromise on speed in any element of your kit.
