Smoother is faster. The more comfortable and less fatigued you are at the end of a 4 hour ride, the stronger you'll be. Like shocks on a race car, the Zertz vibration damping inserts on the Roubaix SL4 help absorb road impact and keep power planted firmly on the road - couple that with a FACT carbon 10r frame and it's still plenty stiff to thrash around in a sprint. Just ask four time Paris-Roubaix champion Tom Boonen.
This stunning Specialized Roubaix SL4 Expert full carbon road bike in excellent condition and 100% ready to ride. The bike has many extra accessories: Cateye Padrone bike computer, Look Keo Classic clipless pedals, and dual aluminum water bottle cages. I am asking for 1100 or best offer.
