Stages Power has been as dominant as it gets, guiding riders to multiple Tour de France victories. This model was made in conjunction with Shimano to perfectly integrate with your Dura-Ace groupset. Each arm gives its own reading that is accurate to within 1.5 percent. With minimal weight addition and data accessed easily through your smartphone, adding this non-drive side crank arm to your setup has no downside. Anyone who wants to collect data to step up their performance can benefit from adding a Stages Dura-Ace 9100 Gen 3 Crank Arm.
