Aero. Fuel. Fit.

Introducing the S-Works Shiv Disc

We developed the fastest bike Kona’s ever seen, but we didn’t spend half a decade focused on just the traditional idea of fast. We wanted to make the most complete triathlon bike ever made. One with a tremendous amount of storage, the perfect fit, easy travel features, and of course, a destiny of setting Kona course records. This is the new shape of speed. This is the S-Works Shiv Disc.

Aero is Everything

The Development

A triathlon bike is only as fast as its integration. Taped-on gels, frame bottles, flat kits—in the eyes of drag, they turn a fast bike into a beach cruiser. The 2011 Shiv, however, was the first to integrate storage without adding drag. And with the Shiv Disc, we’ve created storage and fit features that house more fuel while actually making you faster.

112 Miles of Fuel

So Long to Aid Stations

The first half of the bike is hectic. Getting your legs working, establishing position, properly fueling—it’s stressful. Our athletes requested a design with enough on-board fuel to fly right by aid stations for the first half of the bike, so that’s what we did. Stay focused on the race, establish position, and use the nutrition that works for you.

Hydration Fuelcell

The new Fuelcell holds up to 50 ounces of fluid, all available via an easy-to-route hose that integrates into the cockpit. Through aero testing, we discovered how vital seat tube optimization is, so we shaped it for aerodynamics first and then worked within the airfoil to add plenty of hydration. It’s a win-win.

Nutrition Fuelcell

You need calories to go along with your hydration, which is why we’ve integrated the new Nutrition Fuelcell into the down tube. How many snacks you bring is up to you, but we’ve made room for 4-5 bars, 5-6 chews, or 10-12 gels. Flat kit? We don’t recommend eating one, but you can simply remove the Fuelcell and store it in the down tube.

Fit

Retül-Driven

The four available Shiv sizes have been based upon thousands of Retül Fit data points, ensuring there’s a size that’s perfect for you. 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.
