Trek 520 BB spacers configuration


May I ask someone to post me the close-up image(s) of the bottom bracket (from under the bottom will do) of your newer Trek 520 with Alivio crankset installed from factory? I need to see the spacers configuration used by Trek on this bike on each side of BB. I'm currently upgrading my Marin Four Corners to a similar setup, and this info will help a lot.

My prediction is that Trek used 2*2.5mm spacers on non-drive side, and 1*2.5 on drive side (apposed to official Shimano docs), but it might be also, that they've used 2*2.5+1*0.7mm on NDS and 1*1.8mm on DS. That's what I'm trying to figure out, but I don't have access to the bike to check that out myself.

Thanks a lot!

If you still need it please let me know. I have a 2016 Trek 520 with all factory gears.
