Internal spacer for Redline 401's - length?

(1/2) > >>

funkwit:
Hi all, can you advise?

I'm installing some 401's (American BB with sealed bearings), but when I received the crankset, it didn't have an internal spacer included. I'm trying to track one down, but what length should it be? And would a Profile gold spacer do the job? I see you can buy them on various websites but none of them actually tell you the length and I don't want to buy the wrong one.

Any advice appreciated - thanks fellas.

Different sizes to suit different BB shells mate.

I believe there's an imperial and metric variance.  Measure your BB width overall and then post that up, someone will have your answer for you  :)

Cheers mate. The exact width of the BB is 6.7cm (1983 GT Pro)....

kuwahero:
you will need one approx 58mm long. I have one here that is 59mm which you could file a mm off.

pm me if you want it

Bosh!!!  Sorted   :daumenhoch:


You can actually use a slightly longer spacer with no problems. What happens is one bearing cup sits ever so slightly proud of the BB shell, which in itself isn't a problem. At least that way you're guaranteed not to be putting any incorrect load on the bearings when you tighten everything up.
