ABEC 5 is a standard to which each bearing must pass many tests in order to meet the scheduled requirements including noise testing at high RPM, extremely tight tolerances for the internal diameter, outer diameter, roundness of ball, trueness of races, and surface finish of
all of the above. A much higher standard than ABEC 3, even though only 2 digits difference in name.

The Worlds most intelligent BB?

What is the SABB?

The Self Aligning Bottom Bracket from ROTOR is the standard BB of the Ágilis crankset and is compatible with most cranksets from other major manufacturers. The SABB uses external bearings, but contains a fundamental difference to every other outboard bearing bottom bracket system: the bearings are held within ball-in-socket housings, allowing them to swivel into absolutely parallel alignment with each other, irrespective of any outside influences. This automatic self-alignment of the bearing races occurs independent of any possible frame imperfections or stresses: unparallel faces, non perfect concentricity of the threading in both sides, deformation due to excessive loading, etc. Additionally, due to its user friendliness and simplicity, the consumer can change the bearings without the need of any special tool. Anybody who is tired of replacing their standard BB cups from other brands can easily retrofit the ROTOR SABB system to their bike, guaranteeing thousands of kilometres of care free cycling.
Simple to fit at home.

The “XXX one” Hub Mechanism (Information to be updated)

The “XXX one” Hub Mechanism (The gravity-zero freewheel hub system is covered by pending Australian and international patent applications.) but is dure to have ceramic bearings and a carbon hub.

The “X one” Series 5 Hub Mechanism

The “X one” Series 5 Hub Mechanism (The gravity-zero freewheel hub system is covered by pending Australian and international patent applications.) is fitted to all wheels sets from December 2007 onwards. The Series 5 with increased cam angles and spring tensions lock up is more instant. It eliminates any form of backlash/lag at the hub or pedal: This equals zero lag. In simple terms it is like riding a fixed wheel bike with gears. The “X one” creates a pedalling motion like no other freewheel hub, it propells the riders legs through the position of least mechanical advantage at the top and bottom of each pedal stroke. This moment is sometimes refered to as TDC and BDC, the Top Dead Centre and the Bottom Dead Centre.

The VumaQuad is a 4-arm compact crank fits the emerging 30mm BB standard, has a 30.0mm spindle and 30mm bearings. This crank set is 33% stiffer than the next lightest product on the market and passed the new increased CEN fatigue test at the new standard of 1800 Newtons.

We offer both compact 50/34 and standard 53/39 extra stiff chain rings fitted to a 110mm bolt circle and attached with “NoNuts” system to reduce weight and increase overall crank stiffness. The smaller chain ring is threaded, so we use a larger diameter bolt to increase thread engagement, reduce weight and Stiffen the chain ring – crank arm interface.

There is a ceramic bearing option (with gold bearing cups + $200) comprising ABEC 7 races and Grade 2 balls. Our standard (gray bearing cups) option with ABEC 5 races and Grade 10 steel balls is already 2.5 times rounder than the industry norm.

The VumaQuad is compatible with all 68mm wide bottom brackets with either 1.37″ X 24T English threads or 36mm X 24T Italian threads. The VumaQuad is designed to work with only the VumaQuad bottom bracket bearing cups.
