Bottom bracket compatability question
I have a 10 to 15 year old Felt road bike with a triple crankset and would like to remove the crankset and bottom bracket to install on an older steel frame Origin8 cross/gravel bike. Before I start removing bottom brackets I would like to know if the threads are compatible. Didn't want to take them apart to try them if there is a good chance it wont work. Any thoughts or experiences on these bikes? Thanks.

Good: read everything marked/stamped on the BB and crankset and pump it all through an internet search engine. Read the results carefully.
Not so good: rely on published/remembered/guessed specifications from several years.
BTW, you can probably measure shell widths in situ and guess BSA threads and you'd be 80% there.

I would take out the BB, read what it says, and buy a new one.

I can't imagine either of those bikes being anything but English (BSA) threaded and most likely 68mm shell width.
