This square-taper bottom bracket is a replacement cartridge unit for compatible mountain bikes and straightforward everyday builds. The 68 x 122.5 mm sizing is the key fit information: match both measurements to your existing bottom bracket before ordering, as shell width and spindle length determine crank position and chainline.
The cartridge-bearing construction keeps the assembly compact and practical for replacement. Square-taper systems are valued for their simple crank connection, accessible servicing and broad availability of replacement parts, making this a sensible option for commuters, recreational riders, touring bikes and older MTB setups rather than riders chasing the lowest possible system weight.
A chainline stabiliser helps maintain consistent chain alignment, while the aluminium adapter contributes to the unit’s construction. Check whether your bike requires the standard, E-type or chain-case configuration, and confirm that your crank uses the matching square-taper standard. JIS and ISO square-taper components should not be mixed without carefully accounting for the resulting chainline difference.
A practical choice for anyone replacing a worn square-taper bottom bracket on a compatible MTB, commuter, touring or utility bike.
68 x 122.5 mm sizing
A clearly defined shell width and spindle length make it easier to match the replacement to your existing setup.
Square-taper interface
Designed for cranksets that mount onto a tapered square spindle rather than a splined or external-bearing system.
Cartridge-bearing construction
A compact replacement format suited to straightforward bottom bracket renewal and everyday riding.
Chainline stabiliser
Helps keep the chain running in a consistent line through the drivetrain.
MTB application
Specified for mountain-bike use and suitable for compatible recreational and utility builds.
Multiple configuration options
Standard, E-type and chain-case options are available within the specification, helping cover different frame and drivetrain layouts.
Aluminium adapter
Uses an aluminium adapter as part of the bottom bracket construction.

Generic is a catalogue designation for products presented without a distinct store-brand identity. The term describes the retail classification rather than a separate manufacturer history or geographic origin. Generic-labelled products can still have clearly defined specifications, standards and compatibility requirements. For this component, the catalogue designation is retained while the fitment details identify the relevant road bottom bracket application.
