Title: Oniirii attack crankset
Post by: Benbenben on May 13, 2025, 06:57:21 AM
Hi, I recently installed the Oniirii crankset pictured below for my new road build. Great looking crankset by the way and seems very solid.

One question I have if someone bought that crank or if someone has similar experience with similar set ups. The crankset uses DUB standards & comes with a 2.5mm spacer. Also picture attached. I can't seem to find documentation about where to put that spacer. I have a 68mm BSA threaded also from Onirii. I know that I need that spacer since I had play when everything was tightened without that spacer

So, drive or non drive side? Between BB & frame or between BB & crank?

Thanks!

Since it's a DUB standard I would follow sram's guide on spacers: https://www.sram.com/globalassets/document-hierarchy/compatibility-map/road/dub-choose-a-road-bottom-bracket-compatibility-map.pdf

Sram says for DUB road on BSA 68 you use a 3mm outer right spacer (between BB & crank), page 2. I'm guessing 2.5mm works fine

Yes, I looked at it as well, but not convinced since the space is not same shape.

I would put it between BB & frame,  but it does not seem right to squeeze a metal spacer around the BB shell/carbon area.

If you don't wanna use metal spacer just get spacers from AliExpress
