Specialized S-Works Carbon cranks - we all know they're super light and stiff, but what's the best way to fit a powermeter?
This is it, the Quarq for Specialized spider.
Retaining your crank arms, all you need to do is swap the spider. Measuring the whole system power (not just doubling one leg), these also give you a Power Balance based on internal accelerometer data.
Simply, the best powermeter you can get for your Specialized.
Power measurement in the crankset spider — the heart of your bicycle, its sole job is to convert the effort from both legs to forward motion.
10K™ temperature compensation eliminates temperature effects on power measurement.
AxCad™ accelerometer cadence removes the need for a magnet.
An LED and visible ANT+™ ID streamline installation and operation.
OmniCal™ means you can change chainrings without affecting accuracy.
CR2032 battery – 300 hours of riding time.
+/- 1.5% accuracy
Spider only - crank arms not included.
Quarq power meters have an IPX7 waterproof rating. They feature a 2-year warranty, free firmware updates and Quarq’s acclaimed worldwide support.
Verified with ProTour wins and UCI World Championships, the Quarq for Specialized Power Meter replaces the factory spider on Specialized's S-Works Carbon Crankset. It features Power Balance™, OmniCal™ and compatibility with a wide range of chainrings. Accuracy is +/- 1.5% and ease-of-use takes center stage with the prominent ANT+™ ID, LED indicator and tool-free, user replaceable battery.
The Quarq for Specialized Power Meter is available in full size (130 BCD) and compact (110 BCD) bolt circle diameters, as a spider only. Quarq offers a spider removal and installation tool so the power meter can be installed at your local bike shop. The alternative is to ship your cranks to the Cyclepowermeters for installation, which is a free charge, plus shipping.
