MTB spider power meter
Quarq DZero XX1 Eagle AXS DUB Boost Power Meter Spider
A spider-based power meter that bolts to SRAM XX1 Eagle 8-bolt DUB cranks, measuring total power from both legs. Boost (52mm chainline) version, taking 104 BCD X-Sync Eagle chainrings; arms and ring sold separately.
Highlights
Why we rate it
Both legs measured
Sitting in the spider, it captures combined power from left and right legs.
Ring swaps without fuss
OmniCal keeps accuracy when you change chainring size, and MagicZero zeroes automatically while you ride.
Built for trail
IPX7 sealing and 10K temperature compensation for consistent numbers in mud, rain and cold.
Coin-cell battery
A CR2032 gives roughly 200 hours of riding and swaps without tools.
