We are not ones to rest on our laurels. So when we found ways to make our lightest and stiffest cranks even lighter, we set to work.
  • The new process reduces the weight of our hollow carbon cranks by around another 29g, and to keep up with current assembly trends, we've added a 160mm and most recently 167.5mm length variant. The new Red cranks of the E1 series have an 8-screw direct mount interface, which also allows the installation of a power meter.
  • This variant is basically fitted with one-piece derailleurs in a combination of 50 and 37 teeth, which are ready to help you beat your personal records.
  • Red cranks are available in lengths of 160, 165, 167.5, 170, 172.5 and 175 mm.

Sram, founded in 1987 in the USA, has brought many revolutionary solutions through the years. While the brand flourished, they took other brands under their wings, such as Sachs, Rock Shox, Avid, Truvativ, Zipp or Quarq. At the beginning of the new millennium, Sram focused on components for road cycling while beating concurrence with electronic wireless switching.
