Description

The Zipp VumaQuad Carbon Crankset takes compact crank design and performance to another level. At 560 grams, the Zipp VumaQuad Carbon Crankset 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 a 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. Zipp’s 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 ever measured in the market. The bearings are 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. The Zipp VumaQuad Carbon Crankset is a top of the line lightweight crankset. OneTri is one of the premier retailers for the Zipp VumaQuad Carbon Crankset.

Four-arm Spider: By combining Zipp’s experience with carbon and partnering with the industry’s leading chainring designer, they’ve been able to create a weight-saving four-arm spider that actually fields greater stiffness than any of the heavier five-arm designs on the market.

Chainrings: The stiffness gradient throughout their 53-ttoth chainring is as much as four times less than that of other five-arm chainrings on the market. The final result is a four-arm, 110mm bolt circle diameter chainring that’s at least 14% stiffer than any five-arm/130 BCD chainring on the market.

Carbon Technology: Zipp uses a revolutionary new bonding system with three times more strength than previous systems to encase two separate lugs in the carbon. The result is a featherweight crankset capable of passing, the result is greater stiffness which allows the VumaQuad to pass our battery of internal fatigue tests, including some that are even more rigorous than the new CEN standard.

Compact or full-size versatility: Zipp’s new FullRange 110 bolt circle design lets you run both 50/34 and 53/39 chainrings without any loss of stiffness.

Bearings: Zipp Ceramic Upgrade – If two-and-a-half times rounder than the industry norm still doesn’t leave you with enough margin for guaranteed victory,
Zipp has a ceramic upgrade. The ABEC 7 races and Grade 2 balls conform to the same stratospheric standards as our ZedTech Wheels – not
merely ceramic, but the absolute roundest ceramics used in the industry.
