Bikes: A bunch of old bikes and a few new ones

ISIS was a public domain design and they were made by numerous manufacturers in a huge range of prices and quality. The poor ones were very bad and gave the whole design a bad name.
This is useful info as well. The octalink BB I have is a good one as well (XT quality for a triple mtb crank) so I'll see how well it holds up over time. I'll source out a good quality ISIS BB for my other bike; it's worth trying to find a good one to see how it holds up over time.

This is a useful discussion of ISIS BBs: http://weightweenies.starbike.com/fo...hp?f=3&t=60539
