Sram Red AXS Single Chainring Direct Mount DUB Cranks

Sram Red AXS Single Chainring Direct Mount DUB Cranks

Triathlon. Time trials. Cyclocros. Several disciplines are made for single-plate transmissions. And while the X-Range 2x has a lot of the simplicity of a 1x built in, there are many times when a single chainring is best. Sram Red 1 cranks offer the best mix for cyclists who demand the most: aerodynamics, durability and simplicity.

CHARACTERISTICS

• Single-plate transmissions simplify functionality and reduce weight.
• The 48 and 50 tooth variants have a direct mount aerodynamic chainring.
• Non-aerodynamic chainrings can be installed with a simple tool, allowing gears to be changed quickly and easily.
• Sram X-Sync technology with thin, low teeth provides maximum chain control.
• Laser etched finish on plates is more durable
• The DUB bottom bracket adds durability and simplicity.
• Can be upgraded to power meter.

TECHNOLOGIES

• EXOGRAM: Hollow Carbon construction starts at the crank arms and extends into the spider, maximizing the stiffness-to-weight ratio.
• X-SYNC: Sram X-Sync 1x chainrings provide the highest level of performance and durability. The top edges of the teeth engage the chain before any other traditional triangle-shaped chainring. The thin, sharp tooth profile and rounded edges help with better chain handling. To provide the best possible performance in muddy conditions, X-Sync chainrings have been designed with anti-mud treatment for the inside of the chain links and bearings. Designed in Germany, X-Sync chainrings are an integral part of Sram single chainring drivetrains.
• DUB: The relationship between the bottom bracket and the bearings is the core of DUB technology. It's where rigidity meets durability. Sram has gone one step beyond the conventional mentality and made everything easier by better integrating the relationship between the chainring, cranks, axle and bottom bracket. This is the goal of improving the entire system which equates to better transmission performance.
