There is an informal sale of bike kit during the AGM, if you have something you wish to sell why not bring it and a sign with how much you want.
If you want any of the club jumble then we just ask for a donation of what you think is suitable.
If you think the thing you want is worthless, and you can give it a good home anyway, then just ask one of the club officers to see if you can take it away for free?
