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 power meter to be designed into a SRAM groupset, 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 (39/53t) and compact (34/50t) chain ring sizes, and in 170mm, 172.5mm, and 175mm crankarm lengths. Please note that this system is only compatible with 2012 SRAM Red groupset.

Here's what others have to say...

Has anyone used this power meter with a Campagnolo Super Record 11 spd (2011) 53/39 setup? I've heard fair myth of such a wonder...

Responded on


Campy 11 speed won’t work with this power meter. Thsi is a 10 speed set-up. You will have all kinds of problems, and offend Campy fans everywhere, if you try to use this with your 11 speed Campy. We do have the Campy SRM power meter that would be awesome.

Hit me up directly with any other questions!

Does this power meter fit to my Wilier cento1 SL with SRAM red 10 speed? Which of the other power meters on sale here would fit?

Responded on

Hi Johan,
Yes this is a 10spd crank and should work great with the Wilier cento1 SL .

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 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.
