Technology:


Operating Mode QUARQ
The crankset is the heart of your bicycle. Its sole job is to convert the effort from both legs to forward motion. It is the perfect place to measure power.
Power meters calculate power by measuring the torque (pedal force) and the angular velocity (cadence). Power = torque x cadence.
When you press on the pedals, all parts of the bikes drivetrain displace (flex) slightly under the load. Power meters are designed using finite element analysis to displace in a very controlled manner in specific locations in response to applied load. Strain gauges are used to measure the displacement and thus calculate the applied torque. Reed switches are used to calculate cadence.

DZero
Quarq’s next-generation power meter platform, DZero, is named for the DZero Experiment, one of science’s most accurate and innovative projects to detect subatomic particles moving at the speed of light. With a new measurement circuit, a revised strain gauge design, improved accuracy throughout the pedal stroke and software advances built into the Qalvin App, DZero represents the state of the art in power meter technology. Dual Bluetooth low energy technology and ANT+ let you choose how to capture the data. A simplified product line makes it easier to choose and install the right power meter for your bike. Increased compatibility, including Boost 148 (52 mm chainline) mountain bikes and BB386EVO bottom brackets.

OmniCal™
Power measurement is independent from chainring selection. Switch from road to TT chainrings without impacting accuracy. No recalibration necessary.

Power Balance™
Displays the ratio of power generated in the right drive stroke (first half) versus the left drive stroke (second half). Lets you work on an equal pedal stroke over 360 degrees of rotation.

DUB
Forward thinking and backwards compatible DUB™ BB/Crank technology is the workhorse without restraint. Designed for the most discerning pros. And riders who set it and neglect it. DUB™ is compatible with all major bottom bracket standards. Offering better sealing than ever before, without having to make compromises to fit all frames. Yet it opens the door for a new crank spindle. It’s a new approach that embraces the old. The relationship between bottom bracket spindle and bearing is the core of DUB™ technology. It’s where stiffness meets durability.

-extrem leichtes Gewicht; die Kurbelgarnitur ist deutlich leichter als viele andere Kurbeln mit und ohne Messeinheit
-sehr erhabene Optik (matt schwarzes Carbonfinish und CNC gefräster Spider)
-Endkappen für Kurbelarme im Lieferumfang
-passende Schrauben für 104er Kettenblätter im Lieferumfang
-gedichtetes Batteriefach für handelsübliche Knopfzellen
-Status LED
-sehr gute Haltbarkeit und Schutz vor Wasser/Feuchtigkeit
-Wechsel des Kettenblattes ist ohne Demontage der Kurbel möglich
-Wird von Garmin Geräten sofort gefunden; Kalibrieren und Daten auslesen funktioniert sofort
-gemessene Daten geben sehr präzise Aufschluss über Training und Fitness
-beidseitige Kraftmessung der Kurbelarme (viele Kurbeln haben nur einseitige Messsysteme (Messungenauigkeit))

Negatives:
-Wegen der anderen Directmount Aufnahme können an diese Kurbel keine Kettenblätter direkt verschraubt werden
-Aufgrund der Bauweise sind keine Directmount Kettenblätter montierbar
-Der DUB Distanzeinstellring ist lediglich aus Kunststoff... hier hätte ein Bauteil aus Aluminum o.ä. besser gepasst.
-Der Preis lässt einen schlucken... Diese Investition sollte man tunlichst nur dann machen, wenn man nicht auf den Cent gucken muss oder aber sehr große Trainingsambitionen hat. Mittels Wattmesser kann deutlich effizienter und gezielter trainiert werden, als nur über Herzfrequenz!

=> Ein tolles, teures Stück Technik, was das Trainig sehr stark verbessert.
