My bike has a Shimano Tiagra 4500 BB, I had to replace the first one after about 3,000 miles. The replacement is just showing signs of falling apart, cranks can be moved lateraly, this is after a further 4,000 miles. Is this an 'expected' mileage for this type of BB?
I commute most days all year round so the bike sees all types of weather.
If this is an expected mileage, is there a more robust (but light and easy rolling) BB that could be used?
Ta folks.
