I hope someone may be able to help me out. I have a cross bike with a Nervar crankset ( 50.4bcd ) that has a single 45T chainring and runs on an old Campag Record cup & cone BB. I would like to fit it with some TA 50/40 chainrings that I have and in doing some research on Velobase & Sheldon Brown find that I need a 117mm axle for a double and that the Nervar cranks are ISO, not JIS. I was hoping to find a sealed bearing BB that fit these criteria, but have not had much success and am not keen to mix ISO with JIS unless I really have to. Any help and suggestions welcome. Thanks.
