MTB Bottom Brackets & Cups

MTB Bottom Brackets are built to survive the worst conditions we can throw at them and yet keep turning smoothly. MTB bottom brackets contain sealed cups and O rings keep the bearings dry and contamination free, ensuring as long a life as possible, whatever the conditions. Older mountain bikes may be fitted with a square-taper or ISIS bottom bracket. Newer machines will have an external bottom bracket or a press-fit one.
