Confident pedalling and reduced roadside tinkering make weekend rides more enjoyable. Is the fit correct for the bike and riding style?
⚡ At a Glance
- • Fit and Compatibility: Designed for 68mm shell frames with multiple spindle lengths and standard cup threading
- • Best for: Cyclists using square taper cranksets who need reliable, low-maintenance running
- • Not ideal for: Riders with press-fit shells or non-square taper crank interfaces
Available in five spindle lengths for common crank setups with sealed bearings for stable lubrication. Steel shell construction absorbs tolerance and helps protect the frame while transferring power efficiently.
Accurate chainline and fit - thanks to five spindle length options
Five spindle lengths are available: 118mm, 120mm, 122.5mm, 124.5mm and 127.5mm, covering common crank standards. Cup thread diameter and pitch are specified as 34.798mm and 1.37 x 24TPI for consistent threading.
Matching spindle length reduces chainline issues and helps avoid drivetrain wear. Appropriate selection ensures cranks sit correctly for efficient pedalling.
Long-lasting operation - with sealed bearing structure and good lubrication
Sealed bearings are used within a bearing structure designed for effective lubrication and stable performance. Bearings arrive prepared to limit contamination and maintain smooth rotation under load.
Reduced maintenance intervals and smoother pedalling under varied conditions help keep the bike ride-ready. Bearings resist grime better than open designs, extending service life.
Frame protection and stronger power transfer - thanks to steel shell and integrated design
A steel shell absorbs roundness tolerance at the installation port, while an integrated square taper spindle layout improves contact with the frame. The construction aims to minimise flex at the bottom bracket interface.
Less frame wear during installation and firmer power delivery when standing or sprinting. Riders gain a more direct, responsive feel from the drivetrain.
