The Xelius is a lightweight, comfortable, and super-fast carbon road bike. Climbers, descenders, fast on flat terrain, and comfortable, a bike for many situations. Lighter, more responsive, and aerodynamically efficient, the new Xelius SL embodies the evolution of the classic road bike. We have built the bike with the best components..! Shimano Dura Ace 12-speed complete - with Shimano Ultegra Carbon wheels 38mm...! A beautifully dreamy road bike that leaves nothing to be desired.
