Wanting to try ceramic bearing bottom bracket without breaking the bank, I purchased the Mortop BB1SM ceramic version to have the stock Shimano Deore bottom bracket replaced. It is also very light at 75 g, which is weightless compared to the original bottom bracket that came with the Specialized Pitch Comp that is really heavy.
They say "it's all in the mind" but I think this Mortop bottom bracket is better. Only time will tell how long it will last.
