50cm Surly Cross Check. This bike is versatile. You can set it up as a 1x, 2x or single speed. I have set it all three ways. It is a fun bike that I used on gravel rides and on our local cyclocross course. Frame comes with a Cane Creek headset, and I left the bottom bracket in place. The decals are partially rubbed out as you see in the pictures. I have a new set of decals that I ordered from Surly which will be included. I also have a new set of dropout screws that I will include with the frame. I added a stock image of the screws. Please Google Surly Cross Check geometry chart to get all of the measurements for this 50cm frame.
