Just installed an XT press fit BB on my Yeti SB115. Bearings went in straight, I used a press, now the cranks feel really slow. Is this normal for new BBs? Did I screw something up?
Thanks!
Over-pressed? Over-greased? Pressfit BB install

Back out the preload adjustment on the non drive side until it spins more freely.
Hmm thought all hollow tech had preload
Too much preload. Back it out a bit
Do you have the correct spacers installed and in the correct orientation?
https://si.shimano.com/en/pdfs/dm/MAFC002/DM-MAFC002-11-ENG.pdf Read pages 23-27. You have fc m8120, you’re missing the preload cap but you also probably installed your bb wrong. You do need that preload cap, the crank you have requires it. You should pay a bike mechanic to install your cranks onto your expensive mountain bike.
