A mate has offered me a front wheel with a Mavic 121 'grey' rim. He isn't sure if it is the Ceramic or CD model. How do I tell? (it has been used with a V Brake and the side of the rim has lost the 'grey' coating if that helps).
I'm looking for personal recommendations of places in London where I can get an aluminium frame glass bead blasted.
I know of Armourtex in Hackney but I'd like to get some alternative quotes if possible. Thanks
