Trek Madone SL7 gen 6 T.54 Bike always maintained very regularly by myself as a cycle technician. Ultegra transmission Mechanical - 300 km since last change, only indoors given the weather Sold with another set of wheels: Bontrager aelus elite 35 (new value 1100 €) Bike regularly disassembled, cleaned, lubricated. I'm parting with it to move on to the latest model. It is an aero bike relatively tolerant compared to its competitors. Bike visible on prior request at the store Vélo02 in Château Thierry.
