Hi,
I have a bike that had a 7400 DA bb which died last week when it became recalcitrant.
Eventually when I got around to opening it up I discovered the bearing cage had broken into pieces. It could have been just about to fall apart irrespective but I'm wondering if it was down to using it in UK conditions minus the seal? (The bike belonged to a USPS track rider hence the lack of the plastic seal thingy, I guess.)
I know I can use the unit minus the cages but how effective is the seal if you plan on using it on UK roads?
Any other advise?
