Bottom Brackets & Cups

Like a modern car engine, a good bottom bracket will sit hidden from its owner and do the same job, day in - day out, whatever the weather. The type of bottom bracket depends on the age and type of frame it is to fit. Frames either have a screw thread or are press fit. From older square taper, to the latest press-fit or external bearing – Merlin will stock the correct bottom bracket to keep your cranks turning smoothly.
