Womens Track Sessions 20/09 and 18/10

sorry should have said 1/8"

Shame as I've a 3/32" 14 tooth cog you could have borrowed. My 1/8" one is on my bike at HH so if you're really stuck turn up with a lock ring tool and a chain whip and you can borrow it (I intend to ride the Autumn Omnium event before your session).
