Sram Quarq RED E1 48-35T crankset.

It's the best tool to achieve your best. Our lightest, stiffest and most precise integrated power meter and chainring combination, chosen by our top pros, is now even lighter thanks to a new carbon crank arm design. The SRAM power meter is accurate to +/-1.5% and is not affected by temperature fluctuations, and the consistent 13-tooth gap on the chainrings ensures fast and reliable shifting. Our integrated rings are not only unbeatable in terms of performance, but also incredibly durable. Plus, we offer more crank arm lengths than ever before to make sure this crank is right for you.
