What Type Of Hub Is This? Sm Frame - M-49

Featured Replies

Hey all,

Just wondering if anyone knows what type of rear hub this is in the picture. It isn't like any Bultaco one I have seen before. They are the wheels from a Sammy Miller frame with a M49 engine. Rims seem to be the Bultaco shoulder type rims. Thanks for any help...

Looks like a Grimeca hub to me, as used on Fantic, SWM etc. Nick.

Hi

I agree. I think SM marketed a conical hub for Bultacos in the early seventies that was basically

a Rickman hub. Does anyone else remember and can confirm??

Regards

My Dad used to get these hubs from SM back in 70s when he would build up the SM high boys frames with Bultaco engines. The hub and rims are lighter then the stock Bultaco hubs and shoulder tims. Wish we had kept a couple of the high boy frames.
