Quarq DFour91 Power Meter Crank with 177.5 Arms. Note the picture hairline scratch on one of the crank arms. In addition, see the scratches at the very end of the left crank arm, as pictured. Otherwise, it is in very good condition.


For an additional $140, I will include a pair of Dura Ace 9100 50/34 chain rings which have literally only been used on one 33 mile ride.




Quarq's power meter cranks continue to be reliable, accurate and easy to use. The Dfour91 model accepts Shimano Dura Ace 9100 and Ultegra R8000 road chainrings and offers more data transfer and frame fit compatibility.
