I'm in the process of building up an old 57 cm Sekine Medialle frame (whys it always spelled Medaille?). I'm not sure what year tis. 70's. I plan to replace both the bottom bracket and the crankset.
First, how can I tell if I have ISO, JIS or other bottom bracket. Must I measure the shell?
Second, I am looking at buying a Sugino crank with 1/8" chainring for use with 103mm square taper BB.
Is it possible to find a new BB that'll fit this crank?
Last, I want to run a 7/8 spd cassette. Will I have any problems with the chainline running smoothly?
Thanks for anything
Oh. I've also been scouring the web for a new thumbie shifter - the lever type that mount right to the handlebars. Anyone seen anything like this?
