SRAM Red22 Quarq Powermeter - GXP $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 powermeter training is essential to a cyclist's progression. The new Quarq Red GXP Powermeter is the latest revolution in this field; not only by being the first powermeter 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 Powermeter is Quarq's most sophisticated Powermeter 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 Powermeters -- 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 Powermeter weighing in at an ultra-light claimed weight of 778 grams. The Red Powermeter 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 Powermeters.
Choosing the Quarq Red Powermeter provides you with several advantages over other systems. For one, it's the first and only Powermeter 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 Powermeter systems that require you to mail in your crankset for battery swap-outs, the Red Powermeter 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 Powermeter uses integrated electronics with minimal interconnections. What this means to you is that the new Red system is completely waterproof. The Red Powermeter System is also compatible with various training software such as Training Peaks WKO+, Training Peaks, Golden Cheetah, and Strava. The Red Powermeter operates wirelessly with ANT+, and is offered as a standalone item.
The Quarq Red GXP Powermeter 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.
What community has to say
- Familiarity: I've put it through the wringer
My executive summary - I'm glad I made the purchase and would recommend this option to folks with a SRAM drivetrain. My only complaint is that the price is still a little high. My completely arbitrary high price is $1500.
This is my second power meter, after an early model Power Tap that I used in the mid-aughts. After several years off the bike and not racing, I picked this up to help focus my training. It's an early model - I got it right when they came out in summer'12.
Installation was simple for the most part. I had some minor challenges with magnet placement between BB shell and Cable guide, but it added maybe 10 minutes to the process. That will of course vary by bike.
After 18 months on it, I am quite happy. We've all read how consistency is king with power meters, and I find the results to be just that. The zero offset is easy to remember and simple to execute. I also don't notice any perceivable difference in stiffness between the Quarq crank and the standard Red crank.
I do find that I go through batteries fairly quickly, at least in my perception. But I have nothing to base that on other than perception.
