The Limited-Edition S-Works Shiv Disc features a limited colorway that, depending on the light, is a multitude of different colors. Only 500 individually numbered, limited-edition bikes, and their accompanying custom travel cases, will be available for preorder, so make sure to get yours soon.

We've never been one for dogmatic rules, so with a little defiance of the UCI's rule book, the Shiv, again, sets the new standard for speed. It keeps its aero, fuel, and fit focus, but does so in a whole new light. 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 to 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 S-Works Shiv Disc.

Superlatively aerodynamic. Win Tunnel Engineered. Crosswind-optimized. Not even close to UCI-legal. It might sound like good marketing, but each of these are the core design tenets that went into the Shiv Disc. And while aerodynamics was our number one design priority, we still put a large focus on weight, stiffness, and ride quality to ensure that it’s the best riding and handling triathlon bike you've thrown a leg over.

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 1,000 Retül fits with actual athletes, all to ensure that your ideal fit is 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.

To ensure that it's “race-ready right out of the box,” we’ve spec’d the S-Works Shiv Disc with only the top components. Shimano’s Dura-Ace Di2 with hydraulic disc brakes is in charge of both shifting and braking duties. Our S-Works Power Cranks, meanwhile, provide you with all the data you’d ever need. And it's not only the lightest power meter out there, but it also has the best real-world accuracy at +/-1.5%. For the rolling stock, the Roval CLX 64 Disc wheels are not only extremely aerodynamic, but they're far lighter than other wheels in their class.

• 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. The new "Shape of Speed" philosophy optimizes each tube shape around aerodynamics, weight, and stiffness, and this creates the opportunity for functional integration without compromising speed.

• The cockpit not only takes aerodynamics seriously, but it also allows for a multitude of adjustments. As an added bonus, it easily unbolts from the frame, and the basebar folds down parallel to the fork. This makes packing headaches a thing of the past.

• We've combined our incredibly light and stiff S-Works carbon fiber road cranks with dual-sided power measurement. It's the lightest (440g/172.5mm) and most accurate (+/- 1.5%) power meter available.
