The New VumaQuad
Lightest, Stiffest, Strongest.
Vuma - an Africa word in multiple languages, when translated from Kiswahili means "a good rumor that is spread with the blowing wind," and to move fast, have energy or be spirited.
Our new VumaQuad takes compact crank design and performance to another level. At 570g (including compact rings spindle and bearings cups) it is the lightest stiffest and strongest carbon crank on the market, passing the new, far stricter CEN fatigue test.
The VumaQuad is a 4-arm carbon crank, available with standard and compact chain rings, has a 30.0mm spindle with 30mm external bearings. This crank set is 33% stiffer than the next lightest product on the market and passed the latest CEN fatigue test at the new standard of 1800 Newtons.
q factor is a 146mm
The standard bearings (grey cups) are USA made with ABEC 5 grade races and Grade 10 steel balls, no less than 2.5 times as round as the rest of the industry. We have a (gold) ceramic cup upgrade with ABEC 7 grade races and Grade 2 balls.The spindle, prebonded to the left arm, is aluminum 30mm, with a unique design that allows for weight reduction while retaining structural integrity and durability. The VumaQuad has been fatigue tested beyond 100,000 cycles.
Comes in the following length sizes: 170 mm, 172.5 mm, 175 mm and 180 mm. Alternative chain rings may be purchased as aftermarket items (53/39 or 50/34)
Please note:
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 only with the custom VumaQuad bottom bracket bearing cups.
