Hi everyone , I have a BSA B40 GB engine which is nicely fettled now which is currently in my old C15 frame which is very heavy and not ideal as the chain pitch has now changed so the chain is grinding through the swinging arm slipper after a days riding . There was a much larger rear sprocket on the bike as a C 15 but the gearing was no good for the road work . I'm very happy with the current setup thats on the B40 GB motor . I've looked at Faber frames but a good friend has suggested I also look at Bartram frames . I've looked for a contact for Bartram frames but probably looking in the wrong places as usual so thought I would try the forums advice ? If anyone has a contact please would you forward it on to me ? Or if you own a Bartram frame please could you comment on this also .
Many thanks , Gwilym , Isle of Man
