POWER METER BUYER’S GUIDE ▶ SRM X POWER PEDALS ▶

STAGES GEN 3

The Gen 3 units from Stages have 1.5% accuracy, Bluetooth and ANT+ transmission, and can be found in a range of left hand cranks for Shimano and SRAM, along with dual-sided models for left/right leg balance for those serious about data. Battery life is about 200 hours, and there’s an LED light to indicate functionality. As the unit is factory installed onto a crank, clearance does change so check with your frame manufacturer.

◀ 4IIII POWER METER

Functioning much like the Stages power meter, the 4iiii unit is factory installed onto left hand cranks, although like Stages, there are dual sided models also available. The unit itself is smaller, adding just 9g weight to the crank, and it has 1% accuracy and 100 hour battery life. The unit is Bluetooth and ANT+ compatible. Like Stages, clearance for your frame should be checked with the manufacturer. The downside? The MTB versions are not currently imported by the Australian distributor. From $633

SRM ORIGIN MTB WIRELESS ▶

SRM are the big name in power meters, with decades of experience and a reputation for quality and precision. The Origin is a wireless spider power meter, with options for SRAM and Shimano direct mount cranks. Accuracy is 1%, and they can use both Bluetooth and ANT+ to connect to your own head unit or their own. The 104mm bolt circle diameter (BCD) limits you to a 34-38t chain ring. But with today’s 12-speed cassettes that should not pose a problem if you’re serious about training and racing. $1985 shop-oceania.srm.de
