So I have a Bare knuckle track frame that I've currently been using a Miche bottom bracket on. I have had issues where the cups will tend to come loose over time and just need to be tightened which is usually no problem as it's a rare occurrence.

Today it happened again and now I'm wondering if my bb shell has become stretched/warped.

My question is for those of you with the Miche adjustable bb is there play in the cups up until you fully engage the last thread? Or are the cups tight in the shell from the first thread on?

Thanks for any help on this.
