I tried searching online and couldnt find any answers. I have a 2014 felt F5x and i want to know what is the widest tire i can run on it. I was thinking of doing a gravel grind race soon and would like to run some 35s. I have the stock vittoria xl pro 33s that came with it and while I am sure i could move up to a 35 with the front. I am not sure if the frame would accept a 35. does anyone have any experience with this?
