Vuma -  an Africa word in multiple languages, when translated from Kiswahili means "a good rumour that is spread with the blowing wind,"  it  also means to move fast, have energy or be spirited.

The VumaQuad takes compact crank design and performance to another level. At 560g it is the lightest stiffest and strongest carbon crank on the market. Passing the new, far stricter CEN fatigue test while many other brands were grandfathered in.

This all new four-arm spider comes with your choice of 50/34 or 53/39 chain ring, in a 110mm bolt circle for extra stiffness and in 170, 172.5, 175 and 180mm lengths for the really discerning rider. Our bonding system is 3 times as strong at holding two separate lugs giving a super light, extra stiff crank.

The Q factor is a mere 146mm - the smallest we have measured in the market.

The bearings 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 ceramic upgrade with ABEC  7 races and Grade 2 balls - by far the best in all cycling.

The spindle is aluminum 30mm, with a unique design that allows for weight reduction while retaining structural integrity and durability. The VumaQuad tested beyond 100, 000 cycles at 1800 Newtons.
