I've just replaced the eccentric bottom-bracket on my MTB. A Phil EBB... it's way too pretty to be a bike part. :-) Here are some before and after shots... The "before" EBB has been used for about 4 years. I ended up ovalising it with the set-screws.
On another note... Today I spotted this guy, ready to haul his cargo off-road in an aerodynamic (aero-bars) fashion.
