HOLLOWTECH II
This is a threaded HOLLOWTECH II bottom bracket for mountain bikes with 68 or 73 mm shells. The outboard bearing arrangement places the bearings outside the frame shell, helping balance weight distribution, pedalling stability and smooth rotation without adding unnecessary bulk—the complete assembly weighs an average of 73 g.
The aluminium cups have an anodised finish, while the sealed construction is designed to help keep dirt and water away from the bearing area during everyday trail use. Improved sealing supports consistent rotation, but correct installation still matters: fit the inner cover, grease the threaded cups and use the specified spacer arrangement for your shell width.
It is a straightforward replacement for a compatible crankset, supplied with left- and right-hand threaded cups, outboard bearings, inner cover and installation spacers. Check your frame standard and crank spindle before ordering: this model is for English/BSA threaded shells, works with 24 mm spindles, and is not intended for press-fit frames or 83 mm downhill crank setups.
A practical choice for a mountain-bike owner replacing a worn threaded bottom bracket on a 68 or 73 mm frame with compatible HOLLOWTECH II, 24 mm cranks.
68 / 73 mm shell fit
Designed for compatible English/BSA threaded mountain-bike shells, with the correct spacer arrangement for each width.
HOLLOWTECH II interface
Matches compatible 24 mm crank spindles and uses an outboard bearing layout for stable, smooth pedalling.
Lightweight construction
The complete assembly has an average weight of just 73 g, helping keep your drivetrain setup light.
Improved sealing
Sealed cups help limit dirt and water reaching the bearing area during off-road riding.
Aluminium cups
Anodised aluminium adapters provide a durable, corrosion-resistant finish for regular workshop and trail use.
Complete installation assembly
Includes left- and right-hand threaded cups, outboard bearings, inner cover and the required installation spacers.
Straightforward replacement
A direct service option when excess bearing play or roughness means your existing bottom bracket needs replacing.

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.
