Aluminium hard shell BB30/PF30 unit for road and mountain frames with 46 mm ID BB30/PF30 bottom brackets.
High quality CNC machined and anodised aluminium cups, spacers and centre sleeve. Choice of Chromium Steel, Stainless Steel or Ceramic Hybrid bearings. Bottom bracket is servicable and all parts are available as spares.
Universal design fits 68 and 73 mm wide frames. Spacers are included to use wide cranks on frames with 68 mm shells. Shims and wave-washer are also included. For extra wide fitment (DH bike) or light weight the centre sleeve can be removed and only the cups installed.
Aluminium cups are much stiffer than plastic and prevent the bearings binding due to a tight frame fit, greatly improving bearing life. They can also be machined down to fit frames which are out of tolerance.
6 month no questions asked replacement guarantee on steel and stainless steel bearings. 12 months no questions asked replacement guarantee on stainless steel bearings with CNC Storm drains.
