Speed Concept

Fast. Faster. Fastest ever.
Introducing the third-generation Speed Concept

The Speed Concept is a triathlon bike engineered to be the fastest in its class. But it’s not all aerodynamics and ultra-light carbon. It’s also seamlessly designed hydration and fuelling systems that boost your energy post-swim, keep you strong as you cycle and set you up for your best run ever. We put our best into this bike, and you’ve put your all into training. This is your year – go out and earn what’s yours.

Designed to make you faster than ever

Six minutes. That’s how much faster this Speed Concept is on an Ironman course than previous models. When you’re racing to place, that’s a huge advantage. But these types of gains don’t come easy – it took years to hone the bike’s design to blazing fast perfection. After thousands of iterations and a handful of trips to the wind tunnel, we found every watt and gram possible.

Fast shapes, ultra-light carbon

Drag-reducing Kammtail Virtual Foil tube shapes cut through the air, and ultra-light 800 Series OCLV Carbon allows us to craft these fast aero shapes without compromising on weight.

Redesigned aero frame

From the fork to the headtube and the seat stays, Speed Concept’s frame is meticulously engineered for aero gains and is 180 grams lighter than our previous chassis.

Disc brakes without the weight

Disc brakes deliver more stopping power than rim brakes in any conditions, but they can also add weight. By optimising the design of the fork and the wheels, we only added 170 grams. Most disc brakes designs add 450 grams of weight!

Stay fuelled, stay fast

Carbon fibre and aero tube shapes aren’t the only factors that’ll make you faster. That’s why we put a ton of brainpower into creating the most aerodynamic and intuitive hydration and fuelling systems for Speed Concept. You won’t miss out on free speed, and you’ll stay perfectly gassed up for your ride and run.

A better between-the-arms bottle

Designed to boost aerodynamics and hydration. The built-in straw makes it easy to take a sip, and when you need a refill just grab a bottle from the station and squeeze it into the bottle via the silicone port.

Fully integrated bento box

Built directly into the top tube, you can hold a race’s worth of nutrition inside. Removable dividers let you keep things organised, and a stiff silicone top with a slot makes access easy without sacrificing aerodynamics.

Aero down tube bottle

Designed for drink mix concentrate so you can calibrate your nutrition perfectly. Just squeeze a bit into the BTA’s silicone port to get the right fuel ratio.

Hidden down tube storage

Under the down tube bottle there’s concealed storage that holds an entire flat kit! A CO2 cartridge, Bontrager BITS tool and a tube can fit inside.

A more comfortable, compliant ride

Most tri bikes are… wildly uncomfortable to say the least. Not this one, as it comes with road-smoothing IsoSpeed that’s 30% more compliant than before. Because triathletes naturally sit closer to the nose of the saddle, we did a lot of testing to figure out the best place to put IsoSpeed. The result is a new, tri-specific IsoSpeed with a pivot position that’s much further forward than other road bikes. And if you’re wondering if a more comfortable ride translates to performance improvement – yes. In real-world testing done by Trek’s Performance Research Lab. we’ve found that a more compliant ride is less fatiguing for your body and helps keep you fresher for the run.

Dial in the perfect fit

A great bike fit is absolutely critical for triathletes – you stay planted in your aero position for mile after mile. That’s why the new Speed Concept has a huge fit window and tons of opportunity for adjustment. You can customise every bit of the bars, extensions, towers, pads and more – and we’ve made it quicker and easier to adjust, too.

Travel with ease

Once you’ve got your perfect fit, it’s almost devastating to have to break down your bike for travel. Fear no more – we’ve made it incredibly easy to pop off the base bars and extensions, and your fit positions will be preserved perfectly for when you re-assemble your Speed Concept at your destination.
