SRAM Quarq with Power Balance

Today we received a SRAM Quarq Spider for a Specialized 2012 Venge.

A cool feature is the Power-Balance which shows power variation between left and right, telling you which is your stronger/weaker leg.

 

Here's some more info:

The 2012 Specialized Quarq Power Meter features Power Balance™, OmniCal™, light weight and improved clearance, and compatibility with a wide range of chainrings. The entirely new design, using aluminum-armored, integrated electronics, lifts accuracy to +/- 1.5%. Ease-of-use takes center stage with the prominent ANT+ ID, LED indicator and Quarq’s tool-less, user replaceable battery.

The Specialized Quarq power meter is compatible with Specialized's S-Works crankset and replaces the factory spider. It is available in full size (130BCD) and compact (110BCD) bolt circle diameters - as a spider only or equipped with SRAM Black RED chainrings.

Quarq offers a spider removal and installation tool so the power meter can be installed at your your local bike shop

Features

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.

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