Loud enough ? We could say this bike is fast up a climb, but nothing speaks louder than results. The Xelius SL won l’Alpe d’Huez in the 2015 Tour de France, in the hands of Team FDJ’s Thibaut Pinot. The Xelius SL is a bike that carves up the roads, not the rider. The seatstays of the all-carbon frame curve from the rear axle directly to the top tube, allowing controlled flex that boosts comfort and traction. Our 3D Tubular Technology also reduces mechanical stresses – and yet the SL carbon layup ensures it stays extremely light.
