Looking at getting some GB guards for my crosscheck running 700x42 tyres and not sure if I should get 50mm or 60mm? Thoughts anyone?
I have some 700x42 marathon supremes under 60mm GB guards. They work nicely, although are quite flexy due to the compact frame geometry. I'm having to add a second stay on the rear.
