I have been running 15/47 since my first sprocket change. Also bought a 13 front to learn to wheelie, but it is a horrendous ratio.
Thanks Bertie. 15/47 it will be then.
On the last trip with TK and Greg, I could only keep up on the fast tar sections with TK, by slip streaming behind him.
Technical climbing ability will improve, which is actually the most important consideration.
