What size seat post?
I'm in lewisham and my shed has a few spares.
standard? Not sure. 6pt/TCB? Any ideas?
I've got a few around, maybe a saddle too. I've got a chain in some inner tube round saddle rails and seat stays after somebody walked away with mine. I'm sure reeeen will be able to help you with some other methods.
awesome! Any chance you might have 2 chains?
oh no your 29er saddle with the alien? :(
yeah... Fucking annoyed. Oh well.
