Can someone with an NS Bike Eccentric frame with a SRAM Dub BB do me a favor? I know this worked as some point, but I moved the crank to another bike and now I don't remember the proper spacing.

Here's what I have:
SRAM DUB BSA - 73mm with no spacers
SRAM GX DUB Crankset
- 32T chainring with 3mm offset
- 4.5mm spacer on the chainring side

This setup right now rubs the rear chain stay. If I double up the spaces and add another 2mm space on the chainring side, it compresses the barrings too much. Am I missing something here?

Thanks in advanced.

I am running the same spacer setup that you listed. Maybe run an in-board spacer?

Sorry to take so long. Thanks!!!

I think my 32T chainring had too large an offset, so I dropped it down to a 28T that I had. I'm getting ready to sell this bike, so 28T is just fine and dandy.

Here's the end product.
