Re: Whyisit - Rear hubs leaking

["MICHAEL CARPENTER" <MAIL4CARPENTERS@peoplepc.com>]

Hi David,

Yep, my Seven uses a Nash Metropolitan rear axle which uses the same hubs as 
a Spridget.  I think that I understand about the wobble that you mention but 
I am not sure that I understand about the bearing standing proud of the hub.

Thanks for your help,

Mike C
