2016 Specialized Stumpjumper carbon XL frame. Everything works fabulous on this bike! Only a couple scratches. Otherwise, it looks almost brand new. I have absolutely loved riding it! Over $200 worth of tires on it that have only been ridden on a few times. 27.5 rims. Tires 27.5 x 2.8 Schwalbe. These tires have been totally awesome to ride on! Dropper post works great. Ready to ride!
