right, got them off (good old pull and twist)
now we tried to put some new ones on and they just split. (the rubber bit came out of the top GRR)
so i need a new set of valve stem seals...
where would be the best place to get them as i got mine in a head set at a cost of £58, so not cheap, but even the mighty google isnt giving me any help!
would it be Sir Matthew Humphris of Oxford esquire?
