I run a Giant FCR 2, a sweet 'flat-bar road bike'. I use it for urban commuting and light touring. It really doesn't have that many miles on it but the FSA-brand BB is getting a little creaky on the left side (I wonder if that is the result of my habit of standing and coasting scooter-style!). I think the BB should be more rugged than that (I have a 20-year old Raleigh hybrid that's still smooth as silk), so I'm looking to upgrade the quality of the cartridge this time round.
I've seen BB cartridges from 36.00 to 220.00, and one that caught my eye was a Shimano Deore at a LBS for about 60.00. My question - does more expensive mean better quality or just lighter? If I want something rugged, should I stay away from high-end stuff that may be lighter in weight but not up to hard use?
