Frameset: The EXO3 takes everything we know about-about Advanced Aero Design and pushes it to the limit. Our R&D team has pulled out all the stops in the quest for the fastest and most efficient bike we've ever produced. Every part of the EXO3 has been trimmed and tuned in our endless quest to save every last watt. We've proven every design choice in the wind tunnel now it's up to you to prove you've got what it takes on the road.

Frame tube profiles have been caressed and blended to give a seamless spine that slices through the wind. Reprofiled seat stays have been shortened and dropped to reduced their drag contribution. Front and rear brakes have been integrated into the frame and are hidden from sight in their own aerodynamically profiled cowlings.

Seatpost and handlebars have been redesigned from the ground up, we've trimmed every excess gram of weight and maximized the range of adjustability, helping you to achieve a better fit on your bike for improved performance. The EXO3 is the result of many hours testing on the road and in the wind tunnel and its performance is nothing less than mindblowing.

Groupset: SRAM RED eTAP- Faultless electronic shifting with a huge range of user adjustability options is combined with SRAM's peerless RED groupset. Carbon fibre shift levers, derailleur cages, chainset and the smartest ergonomics on the planet all combine to make SRAM's eTAP a serious contender for the best ever road groupset. With a huge range of add-on shift buttons for bar ends, tri-bar extensions, bar top and beyond SRAM's Red eTAP is supremely versatile making it ideal for triathletes, TT racers and road riders alike. Shimano's Dura-Ace Di2 finally has some serious competition.

Wheelset: Carbon Tri-spoke front and Solid disc rear clincher wheelset: It doesn't get any faster than this. Our incredible Tri-spoke front wheel and solid disc rear wheel both in clincher versions. Lighter, thinner, even more aero the Tri-spoke front is possibly the fastest CTT compliant front wheel we've ever sold, perfect for TT testers and Triathletes. The rear disc wheel weighs in at 1300g and offers matchless aero advantage to all fast riders.

Finishing Kit: We've kept the finishing kit close to home with our own Titanium railed Exocet Tri saddle and Selcof's new Advanced Aero Design cockpit which offers full integration and is artfully sculpted in carbon to deliver minimum weight and maximum positional versatility.

With the launch of the new EXO3 TT /Triathlon bike the rules of engagement have finally changed. Lead, don't follow.
