18! wimp ;)
ssme as putting a 16 on a 26er! What have you got?
10 or maybe 16 ;) .....ok-maths isn't my strong point.
I guessed you were probably riding 42x10 or something, you are that hardcore ;)
Have you decided whether or not your going to singlespeed TransWales ?
No not yet, the plan is to see how training goes. If in July I can do three transwales days back to back then I'll go for it!
