Spider Power Meters for Road Overview
This page contains our spider power meters for road bikes. With a spider-based power meter, you typically keep your existing crank arms and replace your existing spider for the new one. These power meters are very popular as they measure left and right leg power, are relatively affordable, work with almost any crankset and have a long track record of dependability.
Additional Information:
Brands
We carry spider power meters from power2max, ROTOR and Quarq. These are three, highly respected power meter manufacturers.
Options
All of these companies make a similar product at a similar price point. The brand that you go with is largely dependent upon your crankset.
power2max makes power meters for virtually every crankset including SRAM, ROTOR, Specialized, Cannondale, Easton, Race Face, Shimano and more.
Quarq’s newest spiders are mainly intended for use with Quarq cranksets.
ROTOR’s INspider is compatible with ROTOR cranksets.
Quick Product Comparison:
Price
As mentioned above, pricing on these power meters is pretty similar with most units falling in the $500-700 range. The exception is the power2max NG power meters which are the company’s upgraded units and sell for closer to $900-$1,000.
Installation
With a spider-based power meter, you remove the crankset from the bike, replace the spider for the new one with power and reinstall the crankset. Installation isn’t as easy as say a left crank arm or pedal, but assuming you are not making a change to the bottom bracket, it can usually be done at home with some basic tools.
Power Measurement
All of these power meters measure both left and right leg power. Some units are also able to display left and right power balance data.
ANT+/Bluetooth SMART
All of these power meters are dual ANT+ and Bluetooth SMART compatible.
Batteries
The power2max power meters run off of a CR2450 or rechargeable battery, based on the model. The Quarq’s use a CR2032 battery and the ROTOR is rechargeable.
Weight
Most of these power meters weigh between 130 and 170 grams. This is slightly heavier than a standard spider as the power meter spider contains electronics and a battery, but the added weight isn’t typically more than about 50-75 grams.
