Grafton Speedstix advice????

[Tomahawk kid]

after months looking for some M950 cranks & getting no joy (bidding & loosing!) I gave up hope & found some Grafton Joystix, used, stripped & polished at a price which was good for me. I intend to get them anodised black to match the pace stem & Thompson seatpost on my RC 200 F5 but was wondering what Bottom bracket spindle length would give the right chain line for an 8 speed cassette?

Not sure if theyre all the same but i had problems with my Joystix,they kept working loose from the b/b taper on rides,i found out that they need a campag tapered b/b instead of the normal shimano type

they kept working loose from the b/b taper on rides

got that issue, too.

spindle lenght should be 118mm for joystix and 127mm for speedstix.
