Highlights
Why we rate it
Shimano ring fit
The 110 BCD four-arm spider is shaped for Dura-Ace R9100 rings and also takes Ultegra R8000 and 105 R7000 rings.
Dual-leg spider
Measures combined power from both legs, with OmniCal so ring changes don't upset calibration.
Set-and-forget
MagicZero handles zeroing during rides and 10K temperature compensation keeps readings steady.
Carbon DUB arms
Carbon crank arms on a DUB spindle, for any SRAM road DUB bottom bracket.
