I get a nightmare daydream in my head, of getting everything apart, EXCEPT for that darn fixed cup, and getting completely messed up by it being stuck. 😲 Knock on wood. 😉
totally worth it getting a shop to change it out. If the fixed cup is hard, they can throw the bike on a vice and get it off in a few seconds, bingo.
and totally worth it with a un55 type bb cuz then you never will have to deal with it again, especially given how you switch bikes now and then ;-)
even if you do keep this bike for a while, a un55 will last a heck of a long time if its installed properly and they grease the threads well and torque it properly. Could go 25,000kms or more.
dont forget to get the crank arm bolts tightened again after a little while, not uncommon to need a bit of a turn after a while after taking a crank off.
