We're not afraid to say it—our Airlock Schrader Valve Tubes are the best performing, self-sealing bicycle tubes available. That's because they feature our powerful Airlock sealant that coats the tube for permanent protection against punctures. Not only this, but the sealant is designed to work continuously in order to prevent slow leaks from occurring, so erring complete catastrophe, you won't have to worry about flatting when you're riding over debris. We even addressed the common issue of sealant pooling with a completely homogenous design, so the tire/tube combo will always roll smooth and even.

• Dive for the winning gap, bang elbows in the final meters, dissect the most technical descents, all without feeling like you’ve gone ten rounds with the heavyweight champ. Dropped seat stays, and the Tarmac SL7’s carbon seat post and fork make the Allez Sprint supple in the saddle and precise at the bars—all with Tarmac SL7's World Championship-proven geometry. It’s as comfy as it is beautiful. Well, almost
• One innovation over any other helps us deliver the new Allez Sprint’s aerodynamics, power transfer, and handling—Smartweld. Making the fastest bikes in the world out of carbon wasn’t hard enough. We hydroformed the bottom bracket and down tube from a single piece of alloy, built our most complex alloy head tube ever, and then put it all together with Smartweld. It’s what makes the Allez Sprint the first alloy super bike.
• The Allez Sprint is the fastest alloy road bike in history, thanks to the time its sibling, the Tarmac SL7, spent in the wind. It’s details like the most complex alloy head tube we’ve ever made and integrated cables that make it 41 seconds faster over 40km than the previous Allez Sprint. That’s a hell of a facelift. With 41 seconds, you’d have a podium picture in your Insta feed, just saying.
• Whether you’re launching a sprint out of the final corner or attacking from the gun like a young Italian at the Giro, the Allez Sprint, with its one-piece bottom bracket and downtube, delivers the ruthless efficiency of alloy with unprecedented stability. By balancing power at the pedals with input at the bars, the Allez Sprint keeps you fast and confident on the limit.
