Specialized Shiv Expert Disc Tri Bike 2021

We’ve never been ones for dogmatic rules. And with a little defiance of the UCI’s rule book the Shiv sets the new standard for speed—again. It keeps its aero fuel and fit focus but does so in an entirely new and novel way. Yes it has disc brakes. Yes it’s easy to travel with. And yes it takes aero to unheard of heights using storage and fit features that also make you faster. There’s only one bike that’s going to help get you to the top of the podium this season and that’s the Shiv Disc.
Keeping in theme with ‘race-ready right out of the box’ we’ve selected a spec that embodies uncompromising value and unwavering speed. You’ll get Roval’s C38 carbon wheels to keep you rolling fast Shimano’s Ultegra Di2 groupset to deliver crisp always-perfect shifts and our new Sitero Expert saddle.
The incredibly aerodynamic crosswind-optimized and non-UCI-legal FACT carbon frame features all the details you’ve asked for. It’s packable adjustable has our Hydration and Nutrition Fuelcell systems and it makes it easy to find your perfect fit. Compared to the fastest 2011 Shiv setup possible (Fuelcell slammed bars clean cable routing BTA bottle) the Shiv Disc is nearly a minute faster over the Kona course. With a more typical Shiv setup the Shiv Disc is faster by minutes—plural. So no matter how much you need to carry you’re sure to have the fastest setup come race day.
What was that about storage? Just like with the original Shiv the Shiv Disc features both Hydration and Nutrition Fuelcell storage options but we didn’t simply reuse them. Instead we designed them from the ground up. We moved the Hydration Fuelcell from inside the frame to the rear of the bike. Now it’s entirely hidden within the frame (even the hydration hose) which not only allows for more fluid capacity but it also helps with aerodynamics. The Nutrition Fuelcell utilizes the additional volume created by the ‘New Shape of Speed’ for the down tube and this creates plenty of room for snacks. How many snacks? 10-12 gels 4-5 bars or 5-6 chews fit with ease and it can also be removed to easily access the Shimano Di2 A-Junction Box or a flat repair kit
We also made sure that the Shiv is plenty adjustable for you to dial-in your fit. The frame comes in four different sizes that are based on over 1000 Retül fits with actual athletes all to ensure that your ideal fit is achievable. Our Shiv Finder tool makes it easy to determine your size based on your current position so getting your most powerful aerodynamic position is easily achievable.
Adjustability was also high on the list for the aerobars extensions and arm pads so the cockpit is adjustable on nearly every access. Need more or less base bar stack? Simply loosen a single bolt on each side and tilt it up or down. The aerobars themselves also offer plenty of adjustability—fore aft and pad width all with aggressive and relaxed positions in mind. An added bonus of this adjustability is the ease of travel. All you have to do is fold the base bar down to the fork unbolt the cockpit and your Shiv is ready for the bike box. We couldn’t make it any easier.
