QUARQ Dzero & DFour Crank Power Meters and the TyreWiz-Pressure-Sensor

The innovative, user-friendly products, which have been belonging to the SRAM family since 2011, are the reason why thousands of cyclists, including the pros of Team TREK Segafredo and Team Movistar, trust in QUARQ every day. At the heart of this approach are the world’s most popular power meters, QUARQ DZero for road bikes and DFour for mountain bikes. You can choose between power meter cranks or power meter spiders. These watt meters simplify training by providing reliable power measurement of both legs with +/- 1.5% accuracy. Every second of your ride is captured and broadcasted via ANT+ or Bluetooth for use with your favorite cycle computer or SRAM AXS App for smartphones.

SRAM would not be so successful without the innovations and synergies of the SRAM family. Thanks to the technology sharing between QUARQ and the SRAM ROAD and MTB series, the power meter spiders are also available as DZero DUB or DFour DUB versions. With this add-on, you can quickly take your SRAM Rival road bike or GX MTB groupset to a completely new level of performance.

The SRAM RED and Force AXS power meter cranks featuring perfectly integrated QUARQ DZero technology are the top of the line in every respect. The particularly light carbon cranks are part of the SRAM AXS concept, which can be easily customized with the AXS App. You want to upgrade your wireless SRAM road shifting system? No problem with the direct mount AXS power meter spiders for SRAM RED or FORCE cranks.

The innovative QUARQ TyreWiz, the world's first real-time tire pressure sensor for road and mountain bikes, takes the measurement and analysis of performance-related data to a new level. Lightweight, durable, and powered by a long-lasting user-replaceable coin cell battery, TyreWiz monitors air pressure in real-time and relays the data to a bike computer or a smartphone.
