Measures Power at the Crankset
The Quarq CinQo is a bicycle powermeter that is integrated into the crankset of the bicycle. Specifically, the CinQo is a instrumented crank "spider" that mounts on specific production cranksets.
ANT+ Wireless Communication
The ANT+ radio transmits the CinQo's power measurement digitally to other ANT+ compatible bicycle computers. (Think of ANT+ as "Bluetooth" for bicycles.) ANT+ computers include the Garmin Edge 705 and the iBike iAero. The ANT standard is available to all bike computer manufactures, so look for more ANT+ compatible bike computers in the future.
The CinQo System
The CinQo is only a power sensor, so it is comprised of additional components from the following 3rd party manufacturers:
• CinQo Power Sensor
• Compatible Crankset - Choose one of the three available models from SRAM, FSA or Rotor.
• ANT+ Computer - Any ANT+ enabled computer will work (See below for examples or current and future models).
• Analysis Software - Quarq recommends TrainingPeaks WKO+.
Strain Gage Technology
The CinQo powermeter measures power by measuring the torque (pedal force) and the angular velocity (cadence). When you press on the pedals, all parts of the bikes drivetrain displace (flex) slightly under the load. The CinQo spider is carefully designed using Finite Element Analysis to displace in a very controlled manner in specific locations in response to applied load. Strain gages are used to measure the displacement and thus calculate the applied torque.
Strain gage technology has been around for many years and is used in other very popular bicycle powermeters including PowerTap and SRM products. Although the basic measurement principles date back over 50 years, modern solid state electronics have improved greatly allowing high accuracy and low power consumption for optimal battery life.
The CinQo uses 20 strain grids on 10 gages in Quarq proprietary arrangement (Patent Pending).
ANT+ Compatible Computers:
Any ANT+ Compatible computers will work with the Quarq CinQo powermeter. Here are some examples of current conputers that use this protocol:
• Garmin Edge 500
• Garmin Edge 705
• Garmin Edge 310XT
• iBike Sports Aero
• Bontrager Node (1 and 2)
• CycleOps Joule
• Specialized Speedzone Pro
• Garmin Edge 800
Bolt Circle Formats:
CinQos are currently available in 130 BCD and 110 BCD. We also have plans for track (144mm BCD) and mountain bike power meters in the future.
CR2450. Lifetime - 400 hours of riding. User replaceable without tools. Lid is threaded and seals like a contact lens case.
The CinQo is accurate to within +/- 2%. Each CinQo is individually calibrated in Spearfish, SD. The calibration values are stored on the CinQo, for seamless interchangeability with receiving devices.
**Comes with Crankset/Powermeter Only! Bottom Bracket and ANT+ compatible computer sold seperately.
