I recommend this product
Proseasy to fit, less the 30mins from beginning to the end
Incedibly easy to fit with the right tool. Despite what the box says they can, and should, be serviced particularly chain side. Remove the dust seal, tap out the bearing, clean, grease and reassemble

What Is The Difference Between The Bb51B And Bb52B Bottom Brackets?
30 Aug 2016
I find that BB51B bottom brackets only last around 6 months, so is the BB52B a straight upgrade?

The BB52B is just the newer version, there has been no major improvements as far as we're aware, just small updates.
