Details

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.

Additional Information

CNC Storm Drains:

For those riding in wet conditions Monocrome Bottom Brackets are available with CNC Storm Drains. These water drains allow water to escape from the cup before it can corrode or enter the bearing. The drains are invisible once the bottom bracket cups are assembled.

Bearing Type:

Chromium Steel (Monocrome):
Chromium steel caged deep groove ball bearings.  As with all MonocromeTM bearings, these bearings carry a special guarantee with a 6 month no questions asked replacement.

Stainless Steel (Monocrome):
Stainless steel caged deep groove ball bearings.  When purchased with CNC Storm Drains these bearings carry a special guarantee with a 12 month no questions asked replacement.  When purchased without the CNC Storm Drains the standard MonocromeTM 6 month guarantee applies.

Ceramic Hybrid (Enduro):
Ceramic hybrid caged deep groove ball bearings.  Ceramic hybrid bearings have a conventional steel outer race but with ceramic balls inside.  The harder ceramic balls roll a little easier, weigh a little less and the bearings have been designed to minimise rolling friction.   These are ideal bearings for those seeking higher performance and lighter weight.
