Spider-based MTB power meter chainset
FSA Powerbox Carbon MTB ABS 1x Power Meter Chainset
FSA's hollow carbon 1x mountain bike chainset with a power2max-developed spider meter built in. It records total power and cadence from the spider, with a Megatooth narrow-wide ring for chain retention.
Highlights
Why we rate it
Spider-based measurement
Reads power from both legs at the spider, with left/right balance estimated from crank position.
Hollow carbon arms
Hollow UD carbon arms keep the weight down for XC and trail use.
No-magnet cadence
An internal accelerometer handles cadence and the unit auto-zeroes when you stop pedalling.
ANT+ and Bluetooth
Pairs with ANT+ head units and Bluetooth devices; pedal smoothness data is sent over ANT+ only.
