Size Medium. I'm 5'7" and this bike fits well. It would fit someone slightly taller or shorter as well. In almost new condition with very few miles on this beautiful bike. This is a 2016 model which I acquired in 2018. My commute distance has changed and cycling to work every day is no longer a viable option. So this beauty is looking for a new home. Features and included accessories: 18 spd Internal cable routing Hydraulic disc brakes Carbon inserts in front fork Reflective detailing Gel seat Jack stand Mirror Bottle cage Rack Fenders Ergonomic handle bar grips. Many different models of this bike exist. This link is the closest I found online for specs: https://www.specialized.com/us/en/sirrus-elite-disc/p/106262 This was over $2000 new with all the accessories and taxes. Reasonable offers are welcomed. I have a moving coming up and am hoping this bike finds a new home sooner than later. If you are reading this add, it is still available.
