Mark Cavendish’s Cervelo S5

Mark Cavendish kicked off his Tour de France campaign in emphatic style, winning the opening stage and with it the yellow jersey, the first time in his career. The rider from the Isle of Man is riding on a Cervélo S5 that is kitted out with Shimano Dura-Ace Di2 (with junction box placed under the saddle), a 53-39 chainset, an SRM power meter and a KMC black and green chain.

Cavendish’s spare bike, which still has Shimano Dura-Ace Di2, but uses Rotor’s NoQ chainrings (53-38) and Rotor’s new 2INpower power meter.

Cavendish has got some nice top-end equipment at his disposal, including Enve carbon fibre tubular rims, laced to DT Swiss 240 hubs with 25mm Continental tyres.

The British rider has optional Di2 sprint shifters fitted to the inside of the drops, allowing him to more easily change gear from the drops.

A bit of bling comes in the shape of the gold KMC chain and red Ceramic Speed jockey wheels. Ceramic Speed also supplies the headset bearings. The Danish company claims they reduce resistance and are faster than regular steel bearings, but some people say the benefits on a bicycle are negligible.

Cavendish uses are Speedplay pedals, a Rotor chain guard and a Fizik Arione saddle.
