You are bidding on a used Zipp Vuma Quad Crankset with a brand new BB cups and a used pair of BB cups.

In spite of having the BB30 logo this crankset is English standard with a 30 mm spindle diameter.

(the spindle is too long for a BB30 shell and you would need to use a lot of spacers on the sides)

175mm -  53-39T

The used ceramic BB is "rideable" but I would say they are about 60 - 70 % worn.

The new BB is ceramic, original, brand new in the box. 

The original retail price of this frame was about $1200
