Hope Bottom Bracket - Ceramic Bearing

Advantages: Cheap
Disadvantages: Breaks easily

...I have had three or four of these because they were cheap, it turned out that in the long run it was cheaper to save up and buy a decent bottom bracket.

In this case, many people will take their bike to a shop to get it looked at as although changing a bottom bracket is easy enough, it requires a few specialised... Read review

...The Evolve Series of Bottom Bracket from Race Face Have an amazing Spec for the Price, There Retailing at Around £45 for something that is twice as strong as the competitors. When I say Twice as strong this is because the The whole case has been shot penned to harden it and There are two sets of bearings in the drive side of the bottom bracket to allow for great strain to be put on it, as your drive side takes the power to the chain. Plus a few other tricks to make it the strongest BB on the Market. This makes it ideal for trials as the bash ring, when used pushes a lot of force onto the drive side arm of the bottom bracket, causing pits in bearings in most BB. Race face have gone a step further though as the bearing have been bought in and disassembled and the grease replaced with there own mix that is said to increase the life... Read review
