SRAM Quarq Red GXP Power Meter $1,995.00
If you're not training with power, you're probably not trying to win races. Everyone from coaches to sports physiologists agree that power meter training is essential to a cyclist's progression. The new Quarq Red GXP Power Meter is the latest revolution in this field; not only by being the first power meter to be designed into a SRAM gruppo, but also by increasing reading accuracy while decreasing overall weight. If you're looking to take your riding to the next level, there's only one obvious choice.
The Quarq Red GXP Power Meter is Quarq's most sophisticated Power Meter system to date. The Red features SRAM's integrated, carbon crankarms and 2012 Red chainrings. For a rigid attachment, the Red uses a CNC-machined aluminum spider. The result is the holy grail of Power Meters -- a high-performance crankset that feels, looks, and acts like the revolutionary 2012 SRAM Red. You also maintain the hallmark weight savings of SRAM, with the complete Power Meter weighing in at an ultra-light claimed weight of 778 grams. The Red Power Meter is also extremely accurate, operating on the powerful ANT+ wireless system with an expressed accuracy of +/- 1.5%. This, new to 2012, increased accuracy boasts a 0.5% advantage over most SRM Power Meters.
Choosing the Quarq Red Power Meter provides you with several advantages over other systems. For one, it's the first and only Power Meter system to be designed and integrated for use with the 2012 SRAM Red groupset, operating flawlessly with the new Red Yaw front derailleur and Red shifters. Also new to the Red is Quarq's Power Balance technology that displays the ratio of power generated between the drive and non-drive crankarms. This function seeks to improve rider form and efficiency, as you can now quantifiably measure uneven distributions of force in your pedal stroke. Red also features the new Omnical power measurement that makes digital measurement and accuracy independent of the chainrings. This allows you to swap rings without impeding the overall accuracy of the system. Our favorite feature is the game-changing ability to change the system battery yourself. Unlike SRM Power Meter systems that require you to mail in your crankset for battery swap-outs, the Red Power Meter features a tool-less user replacement system as well as a predicted 300+ hours of ride time per battery. This means more time in the saddle and no need for backup cranksets.
The Quarq Red GXP Power Meter uses integrated electronics with minimal interconnections. What this means to you is that the new Red system is completely waterproof. The Red Power Meter System is also compatible with various training software such as Training Peaks WKO+, Training Peaks, Golden Cheetah, and Strava. The Red Power Meter operates wirelessly with ANT+, and is offered as a standalone item.
The Quarq Red GXP Power Meter is available in both standard (39/53) and compact (34/50) chain ring sizes, and in 170mm, 172.5mm, and 175mm crankarm lengths. Please note that this system is only compatible with 2012 SRAM Red gruppo.

Can I use my Rotor compact Aero Q-Rings...
Can I use my Rotor compact Aero Q-Rings (110 bcd, 50/34) with this powermeter?
I'm interested in the SRAM Quarq Red GXP...
I'm interested in the SRAM Quarq Red GXP Powermeter. I currently have SRAM Force derailleurs and shifters on both bikes. Can I use this on my bikes? I was concerned about a compatibility note on the SRAM site mentioning the new Red Yaw front derailleur. Also I guess I just can't buy the derailleur but would need new shifters as well?
I have been running the new SRAM GXP Crankset and Yaw Front Derailleur (2013 Model Year) with old SRAM Rival Shifters with no issue for over 6 months and everything has performed really well. Just note that your trim on the front shifter doesn't function and doesn't need to.
