Try Andy Minns at Border Bikes. Top bloke. Used to be in Berwick until a fire upstairs sorted that out set of premises.
Very, very happy to recommend him & his dad.
I know that others on this here forum have had their bikes serviced there, and IIRC bought bikes from there too, including the aforementioned "Forry".
Other than getting my bike serviced there, I have no other connections with him or his premises.
