Bullseye cranks

Re:

Roger Durham, bullseye original owner and inventor. His bearings were suited to Californian sun and not much else:

Outboard bearings with shims are good too, although not quite as original looking as a Euro BB:

Re:

Hi guys, I was wondering if you can quickly help me? Is there a drawing or instructions online that shows the assembly order of all the shims and spacers? I have a set of these cranks and all seems to be intact buy I'm just guessing at the order of things. Cheers

Hey Eric.

Some time ago I saved me these images here:





Maybe this helps.

It's time to resurrect this thread! The crank has been fitted to the Cannondale since 2014 but I now want it for another build but the Q factor is too big... Although it's been repainted etc. I'm pretty sure none of you would want to swop yours for my extended version.... Unless of course you planning on putting one on an early 'dale in which case; lets talk!

But seriously I now want to change it back to the original spindle length and having reread this I get the impression it was 150mm. Could one of you double check yours and let me know? Thanks

The crank is now off the bike and hopefully these photos show what I need.

What is the measurement from the inner plate to the end of the spindle supposed to be? Mine now measures 140mm.

The spindle of my crank measures 128 mm.

Brilliant, thanks. Just double checking but yours is a gen 2 like mine?

Yes, my crank is also 2nd generation MTB version.

Thanks - I’ll get cutting!
