Description
An essential part of performance cycling, power meters have come to be commonplace among dedicated and committed cyclists looking to boost their times, target their training and make their time on the bike count. With the Quarq DFour91 11R-110 BB30 Power Meter offering compatibility with ANT+ and Bluetooth low energy devices whilst working seamlessly as part of your Shimano Ultegra R8000 or Dura-Ace 9100 groupset, you can be sure of precisely metered power data delivered on demand.
Measuring to within 1.5% accuracy on each leg, this power meter gives you a refined level of calibration, easily adapted to different chainring setups thanks to the Qalvin BLE app and the Omni-Cal feature, clearly and quickly adapting to your setup and meaning that accuracy needn't be affected. Compatible with frames using a BB386EVO bottom bracket and benefiting from free firmware upgrades through the app, this power meter is hugely user-friendly and ideal for any rider wanting an easy and reliable measurement to hone and perfect their routine by bike.
Waterproof to an IPX7 level, this power meter is neatly integrated into your crankset, and, supplied with Exogram carbon fibre crank arms for absolute rigidity, you can be sure that your choice in power meter is going to deliver the lightweight rigidity that you demand from perhaps the most crucial area of your bike. Powered by an easily replaceable CR2032 cell battery, you benefit from over 200 hours of battery life. Tool-less battery changes easily carried out at home, this is a power meter that doesn't tax you too much with its upkeep whilst allowing you an important insight into your power on the road.
