I know the BB shell is 86, instead of the more standard 73mm.
Does that mean I will need cranks with a longer spindle when I upgrade?
Thanks!

Do you mean 68mm, not 86? I don't think there is an 86 mm shell standard. Check this doc out, page 7.

Usually, it just means that you will need to add or delete spacers. The manual for the crankset will tell you if it is compatible and what spacers you would need. It's boost, correct? Reading the specs and reviews, this bike has a QR rear axle. I can't tell if the rear hub is boost (148mm) That will affect the chainring offset. You should find that out if you don't know.

Thanks, looks like 86 is std for press fit (bearings are internal), brain fart on my part. Normal cranks work.
Rear is QR Boost 141, a whole nother weird std. Got an adapter to run non-boost rear 12mm axle hub.

Cool, sounds like you have it figured. I'm not really helping much, sorry and good luck! I do see that the QR141 is boost, didn't know that existed. Since you adapted to 142 TA that in not boost, you may need to consider the chainring offset.
