Ok, my first one lasted only 6 months, but the replacement has lasted me since June 2004. I had about 12 months off due to a broken ankle but that still means that it lasted for over 6 years! My riding in that time has been many hard, long distance rides around Yorkshire Dales, the Clwydians, Snowdonia and Yorkshire Moors. Throw in about 5 Enduros in the same areas as well. Would I buy another one, YES, I'm about to.
I've had to replace my whole BB cause the bearings are not a standard size! I've tried re-engineering the seals but it's not worth the effort. I'm now going to replace with something that is more servicable.
how do i measure the size of a BB from the frame - if i havent got an old BB to measure????

To get the correct BB size you will need to measure the Width of the bottom bracket on the frame. It will be 68mm or 73mm on a Mountain Bike. The axle length depends on the cranks, as a guide, most modern ISIS cranks use a 113mm but there are exceptions
