This SRAM Red BB30 Quarq Powermeter Chainset is no longer available although you may find similar or newer versions below:
The SRAM RED Quarq power meter is a lighter, more accurate power meter completely integrated with the philosophy and performance of SRAM RED groupset.
The RED power meter features Power Balance and OmniCal and comes equipped with SRAM’s X-GlideR chainrings. The sleek new geometry reduces system weight and delivers clearance for oversized frames and aerodynamic chainrings. The only visible power component is the low profile, all aluminum battery case. New stress flow lifts accuracy to +/- 1.5% and makes power measurement independent from chainring selection. Integrated electronics minimize interconnections and reduce exposure to the elements, bringing unmatched durability and reliability. The Installation and operation is a breeze with the LED that signals power on and set zero, clearly visible ANT+TM ID and tool-less, user-replaceable CR2032 battery.
Power Balance uses crankset torque to display the ratio of power generated in the right drive stroke (first half, 0-180°) versus the left drive stroke (second half, 181-360°) for each crank revolution. Power Balance is used by sports scientists to test asymmetry and is an excellent aid for injury recovery.
Power measurement is independent from chainring selection. Swap chainrings without impacting accuracy. No recalibration necessary.
The chainrings are designed for an optimized shifting performance with the Yaw front derailleur. The stiffer rings (5mm 7075-T6 aluminum CNC-machined) feature upshift rivets with an advanced design adopted from SRAM XX. CNC machining allows for precision control of each tooth shape, ramp, and nearly every shifting feature of the chainring. Chainrings, chain, and front derailleur are designed as a single integrated system for optimized performance.
Paired with SRAM’s RED groupset, the RED power meter gives you the professional’s tool set; everything you need to win at any event anywhere in the world.

SRAM Corporation was founded in Chicago, IL (USA) in 1987 by six employees with one component, Gripshift Twist Shifters. Today, SRAM’s commitment and growth can be measured by its 1,500 employees, its 150+ cycling products, and it’s 12 facilities worldwide. SRAM has found tremendous growth through innovative products, unparallel customer service, strong sales, and complimentary acquisitions. SRAM acquisitions include Sachs Bicycle Components, purchased in 1997, a leading manufacturer of chains, cassettes and hubs. In 2002 SRAM purchased RockShox, the world’s mountain bike suspension specialist. 2004 brought the purchase of both Avid brakes and Truvativ cranks and components. The addition of these companies has allowed SRAM to grow into the world’s second largest component supplier to the cycling industry. SRAM's core philosophy is to make cycling better. Their commitment is expressed in their local, national and international team and event sponsorship.
