Sram Red E1 Powermeter 33/46T 12V 172.5mm DUB Carbon - Black

Sram's lightest, stiffest and most accurate integrated power meter and chainring combination just got lighter with a new carbon crank arm construction.
SRAM's power meter is accurate to +/-1.5% and is unaffected by temperature changes, and the consistent 13-tooth gap on the rings ensures fast and reliable shifts.
Not only unbeatable on performance, our integrated chainrings are also incredibly long lasting.

- 29 grams lighter than the previous generation
- The power meter is fully integrated into the chainring
- Ultra light hollow carbon crank arms
- Measure the power on both crank arms
