Can't hold the Mayo

On the much-anticipated fourth stage of the Dauphiné Libéré, there was no holding back among the best riders in the race as they set off to complete a 21.6 kilometre ride against the clock up the fearsome climb of Le Mont Ventoux. Tim Maloney takes a look at the race-winning machine - Iban Mayo's Orbea TT climbing prototype.

When Iban Mayo rode this unique Orbea climbing bike to victory atop le Mont Ventoux in a time of 55 minutes and 52 seconds, the tenacious Basque mountain man not only surpassed American Jon Vaughters' previous TT record on the mountain by almost a minute, he also retook the lead in the race, maintaining his advantage all the way to the finish in Grenoble three days later.

Specially made for Mayo and weighing in right on the UCI limit, Mayo's uphill only rig features Columbus Starship TIG-welded aluminum tubing with a special ultra-tight rear triangle configuration, including an inclined and indented seat tube that places the rear wheel closer to the bottom bracket. According to the Euskaltel mechanic, the tighter geometry enhances Mayo's climbing efficiency, of utmost importance in an uphill race against the clock.

The Mont Ventoux time trial certainly provided a great test-bed for the Stage 16 L'Alpe d'Huez time trial at the upcoming Tour de France, and based on Mayo's success on this bike at the Dauphiné, the Orbea prototype is sure to be seen on the start ramp in Bourg d'Oisans on July 21. Don't look too close with its sloping geometry, though - otherwise you might mistake it for a mountain bike!
