The Specialized S-Works SHIV of Tim Don

Tim Don has is famous for his run which brought him to the 2006 ITU Olympic distance World Championship in Lausanne and a bronze medal at the 2014 Ironman 70.3 Worlds. But when he set an Ironman brand record of 7:40:23 at Ironman Brazil in May, a key to his performance was his 4:06:56 bike split which was 19:34 better than the next best effort by Patrick Evoe.

Don had always been a strong ITU draft legal cyclist, as witnessed by his 2006 World Championship gold at Lausanne where he made a solo charge to bridge a one minute gap on the leaders to make his victory possible. But Don had never posted such an impressive bike split at the Ironman distance until he rode his Specialized S-Works SHIV at Florianopolis.

Here is a closer look at Don’s race bike with Shimano Dura-Ace Di2 components, a prototype disc wheel from Roval, Specialized S-Works cranks, a new Sitero saddle and a CeramicSpeed Oversized Pulley Wheel System and UFO chain.

Tim Don is 5-feet 8-inches tall, weighs 142 pounds and rides this size-small Specialized S-Works SHIV.

Don uses TriRig Omega X brakes with SwissStop Carbon Brake Pads.

The front end uses Drag2Zero pads and arm rests, an ENVE base bar with aero-shaped Drag 2Zero extension poles made with Formula One grade carbon fiber. Armrest width is quite narrow, more like a bike racer than a triathlete.

The bike computer is Polar M460. Specialized also added a magnet kit for the hydration tube. Pedals are Speedplay Aero.

Tim Don rides Specialized S-Works 167.5mm cranks with 55/42, and a Ceramic Speed UFO chain.

Saddle is the new Sitero, which looks like the old Sitero and the Specialized Power saddles (for road cycling) mated and had a baby. (And truly, the Power saddles' genes took over.)

Don’s rear wheel is a “disc wheel prototype 007 from Roval that is still in development” with a 26mm Specialized Turbo Cotton tire.

The disc prototype has a lenticular shape on the left but is flat on the right to accommodate the cassette.
