This is a nice 48cm 2012 Pinarello Cross CX frame set. It's a 48cm, but as with many italian companies it fits larger, notice the almost 52 cm top tube in the attached geometry. For example I rode a 54cm Specialized Tarmac or a 52 Cannondale System Six, and I rode this with a 110 stem.
I got it from a friend who didn't ride it much. I raced it probably 6 or 7 times in 2012 and it's hung in a closet since then. Good used condition, some scratches and paint chips as you'd expect from a cross bike that was raced. Some paint chips were touched up, others weren't. Has a down tube bottle cage mount that is simply taped over in the pictures.
Bike is designed to not use a front derailleur, but I chose to put one on. I'm including the Problem Solvers pulley for the front derailleur as well as the Campagnolo braze on adapter. Also including the front Problem Solvers cable hanger. The seat post and 100mm stem match, and are also included. The seat post lost a bolt somewhere along the way, but that's easily replaceable. Italian threaded BB. Really cool bike, was fun to race and always got compliments. I'm just not racing cross serious enough anytime soon to hold on to it. Feel free to ask any questions, or if you need additional pictures of anything specific.
