About the 4iiii Podium Shimano DURA-ACE 9100 Dual-Sided Crankset
The 4iiii Podium Shimano DURA-ACE 9100 Dual-Sided Crankset combines 4iiii’s patent pending 3-D tri-axial strain gauge technology with Shimano’s top-end DURA-ACE 9100 crankset. In addition to +/- 1.5% accuracy and dual ANT+ and Bluetooth SMART compatibility, the Podium features a rechargeable lithium ion battery with a 60-hour battery life. The pod on the new Podium is also approximately 10% slimmer than its predecessor (the PRECISION).
The 4iiii Podium Shimano DURA-ACE 9100 Dual-Sided Crankset also features independent left/right power measurement. With a power sensor located on the inside of both crank arms, the power meter can measure the force generated by each leg individually. The new Podium is also extremely lightweight, adding approximately 40 grams to the Shimano DA 9100 crankset.

- Chainrings: 50/34 | 52/36 | 53/39
- Crank arm lengths: 165 mm | 170 mm | 172.5 mm | 175 mm
