Quarq DFour DUB Spider with Wattmeter for Shimano Chainrings
4 In stockThis spider is made for Quarq's cranksets and mounts with 8 screws.
It is made for Shimano Dura'Ace R9100 but also fits Ultegra R8000 and 105 R7000 chainrings. However, it will not match the look with Ultegra or 105 blades.
The wattmeter can be connected to your bike computer with ANT+, Bluetooth and it can work with your phone via the Qalvin App.
The wattmeter itself sits in the spider, and it measures with an accuracy down to 1.5%.
The Spider has AxCad, so you don't need to use a cadence magnet.
The wattmeter uses a CR2032 battery and it lasts for up to 200 hours.
With OmniCal, you can also change your chainrings and still maintain the accuracy of 1.5%.
When you drive, it can also give you a better sense of balance, so you can see whether you step more with your right or left leg.
