Default Bottom Bracket Spindle Collars

Greetings All,

I'm sure this is a familiar theme. I have a 1986 Wicked Fat Chance, and as with many others one of the aluminum bottom bracket spindle collars has cracked. I had seen in a post several years ago that Rody Walter at Groovy Cycle Works sold replacement collars. Unfortunately, this is no longer the case. He suggested that I contact Chris Chance at the new Fat Chance website, and the support folks there suggested that I ask in one of the user groups :-/

Are there any sources of replacement collars or suitable substitutes?

I'm not aware of any alternatives, although it's a really simple part. I wonder if Rody would be willing to share the measurements? I'm sure a machine shop could crank these out at a reasonable price if we wanted to do a run.

The collar on my non-drive-side just split too. Bummer they are NLA.

However, back in the day, Cooks Bros used to offer BB's with a similar smooth spindle and collars. The cool set-up was to stack spacers on the drive-side, and use only one collar on the non-drive side. For the "factory" set-up, you would measure the non-drive-side spacing (as accurately as possible), then fit a spacer stack in place of the remaining collar. Viola - perfectly set-up, no-collar BB!

Not OEM and you'd have to verify the dimensions but... this

For those looking for replacement collars, these are a higher quality than the originals and what we used at Grove for the original Hot Rods.

Sized to fit the Fat spindles:

Aren't these a bit wide compared to the OEM collars? I am about ready to have these machined and have a batch made if anyone is interested? I will only do so if its worth the demand...
