Look ZED 1 Monobloc Crankset: RADICAL 1-Piece Design - Adjustable Arm Length & BCD (Near Mint+)
This wild revolutionary crank was originally designed for the LOOK 596. It claims to have double the stiffness-to-weight ratio of the Dura Ace FC-7900, thanks to it's ridiculously huge spindle and completely integrated design. It uses a special pedal axle unit (not included) that rotates to choose different arm lengths, and has two separate sets of chainring bolt holes for 110mm & 130mm chainrings. The both crank arms are permanently connected to the spindle as a complete unit, and the non-drive arm slides through the oversized 65mm BB shell. Here's a video of installation process.
Yes, this crank ONLY works with the LOOK 596 and a few other LOOK models.
Near mint, almost new shape! There's just the slightest scuffs on the arm ends, and almost perfect otherwise.
