I'm trying to install a set of SRAM NX DUB cranks on a 2016 jekyll. But the spindle is to long. I've read SRAM made a bb30 spindle in the past but it doesn't look like that's the case any longer. Any suggestions on options? I've tried SRAMs Pf30 and a bsa 30 with SRAMs adapter. The adapter is to large to fit into the bottom bracket. And the PF30 is also to large.

Are the cranks you're fitting for boost spacing? And you need a BB30 DUB bottom bracket, not sure what adapter you're trying to fit, tbh

I don't think its a boost model.

Its this.
Sram Nx Eagle Dub Groupset (Rear Der, Trigger Shifter W Clamp, Crankset Dub 12S W Dm 32T X-Sync Chainring, Chain 126 Links 12S,Cassette Xg-1230 11-50T, Chaingap Gauge)

I cannot seem to locate an actual BB30 DUB bottom bracket. Every shop I've talked to tells me they don't exist. I have found a reference for road bikes, but I can't find a set I can buy.

I also tried using this with a BSA DBU BB. But the adapter doesn't fit in to the BB Shell of the frame.

https://www.sram.com/en/sram/models/bb-dub-bb30-a1 ??? It exists and are in stock. Tell your local shops to order: 00.6418.017.000 or QBP part CK2194 provided your frame actually is a BB30 standard. If your Jekyll has Ai offset you'll need a different chainring than the one provided with the crankset.

And back to the spindle being too long, photos would help us ascertain what's going on exactly Are you adding the correct spacers and adjusting the preload? Get the right bottom bracket sorted first or this is all pointless

As far as the spindle goes, the difference between boost and non boost is in the spacers. The DUB bb will have all you need, including instructions. The chainring offset is different for boost and non boost; 3mm for boost, and 6mm for non boost.

Finally got it done, I ended using the Dub BB30 to work with the crankset https://www.instagram.com/p/CmIVLbtN0IR/?igshid=NTdlMDg3MTY= Thanks for the help.
