I just bought a EAI Bare Knucle and was intalling a Dura ace sealed botton bracket that came from a bike that had a double chain ring on it.
After intalling the Dura ace cranks on it,the right crank arm rubbs against the chain stays.
what size botton bracket spinddle should I get to avoid issues with the chain line.
Are there any other solutions to my problem?
Thanks for any and all the help.

That probably isn't a chainline issue. It's the crankset. the lips on the inside for the inner chainring could be ground off to give more clearance.

its not your bb, its the road cranks

Thanks for the help.
Problem solved.
It was the road cranks.
I changed them to some Sugino RD2 and there is not problem.
Thanks again.
Happy riding.
