SKF may be an international leader in bearing design and manufacturing, but they're no leader in BBs, in my limited experience. I bought one of their ISIS BBs 3-4 years ago. It did not fit well from the beginning on 2 different bikes which have had no trouble with 3-4 other makers BBs. It would bind slightly and not spin well. No amount of loosening on the nondrive cup would remedy the problem. QBP carried SKF BBs only 1 season, and I'm speculating that it's because they got fed up with returns and warranty claims.

Positron - wanna buy a SKF ISIS BB, installed twice and hardly any use (<100 miles)? I paid $60, I'll let you have it for $20+ship.

AFA other BB recommendation goes, square taper BBs are very reliable. I own several UN72s, never had a bad one. The problem with ST lies in the crank/BB interface. Over time they can get loose, the square can get wallowed out, then the crank is ruined. Normally the spindle is steel and the crank is Al, so it goes first. This was an issue with ST cranks/BBs back in the '90s, mostly on MTBs.

This is why ISIS BBs were invented. The isis interface has about 3X the engagement area with crank arm than a ST. I've never heard of an ISIS crank arm getting wallowed out. However, ISIS has it's own problem. The larger diameter spindle (in the same diameter BB cartridge, restricted by the diameter of a std frame BB shell), forces you to use smaller diameter balls in the cartridge bearing, and they tend to not spin as easily or last as long. This causes premature BB failures, especially in MTB application.

This shortcoming eventually led to the development of the now popular outboard bearing style of BB, branded as Shimano, Truvativ, FSA etc. Moving the cartridge bearings outside lets you use bigger balls. The wider bearing points support the spindle better, although at the expense of greater Q factor.

You can still buy any of these three bb/crank systems, although choices are limited for the older two (ST, ISIS). Most any will work for touring if installed and maintained properly. If you're a strong, big person, then consider the current outboard bearing style BB/cranks since they have the strongest, best supported spindle.

I had a new experience last week. Twenty miles into a ride I noticed the front derailleur was rubbing chain on top ring. I guessed the cable was fraying and stretched, and hoped I'd get home before it broke. Instead I found the crank arm fixing bolt loose. The ISIS crank arm looked OK, no major damage, tightened it up and back to riding. I might not have got away with that on a ST.

BTW, Nashbar sells a good value ISIS BB, branded Nashbar ISIS (actually made by TH Industries / FSA).

OP - I may have overlooked it, but it's worth mentioning that each BB type requires it's own special tool, some of which cost as much or more than the BB itself. Park is a good source of these tools.
