Hello gang, i am looking to ride the C2C here in northern england and some of the track is rough. People have done it on their road bikes but beefed up the tyres they ride on.

I currently have gp4000 and only 20mm wide, so i think i will need to buy something much more suited to the dirt tracks.

can anyone advise on how wide i can go on this bike, and any recomendations?

Vittoria Randonneurs 700cx28mm has been recommended in my searches however i cant work out the size my bike can handle. Others have said 35mm is nice but i dont think that will work on a road bike.

thanks for any help
