Zipp VumaQuad 50/34 Compact Crankset

| Weight: | 580 grams |
| Price: | $900 |
The Zipp VumaQuad compact crankset is a very high end component that’s available with Zipp’s own ceramic cup and bearing BB. Opt to use the spacer kit and this crankset will work with most BB30 setups.
This crankset is very light and stiff. Zipp claims an 11 percent increase in rigidity over Dura Ace 7800. That’s a very bold claim when one considers the fact that VumaQuad is almost 200 grams lighter than DA or Campy Record. One of the ways Zipp has achieved this weight savings is with an unorthodox 4-bold chainring system. This setup makes for a very unique and clean looking design, however, it could be challenging to find replacement parts if you need them in the future. The other advantage to the 4-bolt design is the ability to switch between compact 50/34 chainrings and standard 53/39 rings. This makes the VumaQuad a very versatile choice when compared to other cranks in this price range.

Zipp says the chainrings feature a special design which allows for accurate shifts and no flex under power. The VumaQuad is available in four crank-arm lengths and two bottom bracket options. The premium, ceramic bearing and cup option will set you back and extra $200 versus the base model BB.
