Our Aero Advantage


Competition Busting TT & Triathlon Bike

Stealth TT Bike

The Stealth has carried more cyclists through more seasons of competition than any other TT / Triathlon frame. The Stealth was the first TT-specific carbon frame to bring high-end aero performance to the masses and it's still going strong today

Years of development means the Stealth frame boasts a refined and assured ride. It has a slightly less extreme position than our Exocet TT bike, but still delivers incredible speed to a broad range of cyclists. Being positioned slightly higher is favoured by less flexible riders, as well as by Triathletes who need comfort for endurance, to minimise hip-flexor cramp for the run ahead.

With a wide range of groupsets available, your ultra-fast dream aero bike is here waiting for you. The Stealth is the perfect partner for TT and Triathlon success this season and beyond.
