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

Speed Concept is a triathlon bike engineered to be fastest in its class. But it’s not all aerodynamics and ultra-light carbon. It’s also seamlessly designed hydration and fueling 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 ounce possible.

Learn how we made it aero

Stay fueled, stay fast

Carbon fiber 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 fueling 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 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 farther 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 customize 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.
