Befiore I buy anymore that don't fit, Can someone measure the widest point of a 2.1 x 26 tyre when inflated. I'm struggling with the width between the chainstays and a 2.3 deffo don't go in.
It depends how wide your rims are. As I am sure you already know some brands measure up differently. Contis are always narrow in the same size compared to Michelin and so on.
