SRAM RED AXS Powermeter Crank - DUB - 48/35T - grey

SRAM RED AXS Powermeter Crank - DUB - 48/35T - grey

The SRAM RED AXS™ Powermeter throws tradition overboard and breaks through to a new level of performance in the process. By the product designers of SRAM reduced the chainring size and increased the transmission range of the cassette, they have redefined the gear gradation on the road bike from scratch and designed. This design innovation hears on the name X-Range. At the same time, the 13-tooth gear jump between the chainrings was retained to guarantee precise shifting in any setup. The result is a more usable gear ratio in all configurations and fundamentally better shifting. The RED AXS™ powermeter also features DZero™, Quarq's premium wireless power measurement system integrated into the crankset. Thanks to a professional performance-tuned training you are ready to climb the cycling Olympus.

The SRAM RED Carbon crank arms are completely hollow thanks to Exogram technology. The X Range Direct Mount chainrings harmonize perfectly with the Yaw technology of the RED eTap AXS derailleur and thus offer an outstanding and low-friction shifting. Like the current SRAM MTB cranks, the SRAM RED crank is equipped with the universal DUB (Durable Unified Bottom Bracket) crankshaft, which can be used in all standard crankcases. It additionally increases the stiffness. The bearing clearance is adjusted via an adjustment ring.

Performance features of SRAM RED AXS Powermeter:

  • 2-speed chainring setup
  • The X-Range™ technology offers in conjunction with the RED 12-speed cassette a wider ratio range and more comfortable gear graduation, so you're always in the right gear
  • the powermeter is fully integrated into the chainring combo and thus additionally only 36g light
  • the power measurement has an accuracy of +/-1.5% and is not affected by changing weather conditions during the ride
  • Power Balance measures separate values for the left and right leg
  • Improved front derailleur shifting performance for crisp and precise shifts
  • Unique Direct Mount chainring design (not SRAM MTB DM compatible) allows for a lighter stiffer and more durable crankset
  • DUB™ crankshafts provide added durability, easy installation & maximum compatibility
  • Material crank arms: carbon
  • Material chainrings: aluminum

SRAM RED AXS power meter crank technologies.


AXS™ is SRAM's integrated wireless platform for connecting electronic bike components with software. The SRAM AXS™ app allows riders not only to check battery levels, influence shifting behavior and configure controls according to personal preferences, but also to create maintenance schedules and update firmware.


Hollow carbon construction starts in the crank arm and extends into the crank spider. It provides an optimal stiffness-to-weight ratio.


The derailleur cage rotates and is thus in a constant angular relationship with the chain. The Yaw technology enables trim-free shifting. The shift transitions are thus more direct and precise and in combination with the new Red crank and Red chainrings, the Yaw forms a perfect unit with the chain. Thus, the Yaw technology provides unprecedented performance when shifting forward.


Road bikes are faster and more powerful than ever before, and riders continue to show what bikes with road handlebars are capable of. X-Range™ is the gear ratio for the modern way to ride a road bike. SRAM has completely redesigned the road bike transmission, for more gear range, a more pleasant and more usable gear gradation and thanks to AXS™ also smarter shift settings. With X-Range™ you are always in the right gear.

DUB™ (Durable Unified Bottom Bracket).

DUB™ technology features a sophisticated bottom bracket design and a new crankshaft design. Together, they allow for a more unified approach to bottom bracket fit and a better seal against contamination. Now everyone can benefit from unprecedented durability.

Scope of delivery:

Crank incl. chainrings, without bearing shells.

Note: A bottom bracket is not included and must be purchased separately.
