Bottom bracket type
Threaded HOLLOWTECH II
This threaded bottom bracket is designed for HOLLOWTECH II cranksets on mountain bikes with a 68 mm or 73 mm shell. The outboard bearing layout supports a stable crank interface while keeping the assembly light at an average 73 g.
The aluminium cups and spacers feature an anodised finish, while the small ball bearings are designed to provide smooth rotation and dependable day-to-day performance. Threaded installation also makes servicing more straightforward than a press-fit system, provided your frame uses the correct shell standard.
For a 68 mm or 73 mm English/BSA threaded shell, this is a focused replacement option when you want a lightweight XTR-series bottom bracket without changing your crankset. A 2.5 mm spacer is required for either shell width; grease the cups before installation and tighten them to 35–50 N·m.
A suitable choice for mountain-bike owners running a threaded English/BSA shell and HOLLOWTECH II crankset who need a lightweight replacement bottom bracket.
HOLLOWTECH II interface
Designed for HOLLOWTECH II cranksets, helping maintain a stable crank and drivetrain connection.
68 / 73 mm shell fit
Compatible with the two common threaded mountain-bike shell widths, subject to the correct crankset and frame standard.
Lightweight construction
The published average weight is just 73 g, keeping unnecessary mass out of the drivetrain.
Anodised aluminium cups
Aluminium adapters and spacers provide a lightweight external-cup construction with an anodised finish.
Smooth rotation
The small ball-bearing arrangement is intended to deliver consistent, smooth crank rotation during everyday riding.
Threaded serviceability
Threaded cups are straightforward to remove and install with the appropriate bottom-bracket tools, making future servicing practical.
Spacer included in the setup
A 2.5 mm spacer is required for both 68 mm and 73 mm shells, so confirm the installation arrangement before tightening.

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.
