Sprocket??? I thought that was the dog in Fraggle Rock!!
Is it the spikey round thing the metal drive belt goes round?
I've got a choice of 14 or 15 front with a 40 something on the back, will try both if I can be ar*ed swapping them between sessions.
That's assuming I go, mum's been taken into hospital and if I can get a refund I'll be ducking out of this one.

If not I'll be there on fast return standby and possibly not with my head in the right frame of mind, mum's told me not to be a d*ck head an waste over £200.
