I have been interested in power meters, and of course am interested in the soon-to-be-released Quarq.
I called up Quarq, and got to talk to a prinicipal in the firm (Mrs. Meyer, the wife of the engineer, James Meyer). I asked her about crankset compatibility, especially. I have a Campy Ultra-Torque, which isn't on the list of compatible cranksets. No Campy or Shimono, because the crank arm can't be integrated with the spider. She said
eventually they may have a CinQo (the crankset power meter) that can work with such cranksets, but they are focused right now on getting their product to market with their compatible cranksets.
To get a Quarq CinQo would mean removing my beloved 643 gm Campy UT, and purchasing a compatible replacement. These choices are not very inviting. They are all low end and heavy. The CinQo is specific for each crankset, as the electronics are integrated with the spider. If Quarq eventually makes a CinQo for a better crankset, you won't be able to upgrade.
The website has been recently updated, and lists the crankarm compatibility:
Crank Arms Compatibility:
The CinQo is designed for attachment to production cranksets with separate spider assemblies.
First Production Run (130mm BCD only):
* FSA Team Issue
* SRAM S900
* Bontrager Race X Lite
* Truvativ Rouleur Carbon
Future Production Runs:
* FSA Krono TT
* Cannondale SI Hollowgram
* Specialized S-Works Carbon
* Rotor Agilis
* Sibex Sports
* FSA Carbon Pro Track
We will continue to increase our list of compatible cranks as we move forward.
* Since the CinQo replaces the spider on stock cranksets, cranks that have an integrated spider and crank arm such as Shimano or Campagnolo will not be compatible with the CinQo.

The question is, are any of these cranksets acceptable?
The
FSA Team Issue crankset and bottom bracket weighs 911 gms.

The
SRAM S900 is also low end, weighing 830 grams (without BB)

The
Race X Lite GXP weighs 935 gms.

The
Truvativ Rouleur Carbon weighs 835 gms.

The options listed under Future Production Runs don't look any better. The S-Works would have potential, but it is specific for Specialized frames with oversized bottom bracket shell.
As it stands now, to get a Quarq will necessitate tossing the high end lightweight crankset that potential Quarq customers surely have, for a low end heavy replacement. I don't see how this is going to work.
