🚀 Technological Depth

1️⃣ X-Range™ Gearing Technology 🔄

SRAM has completely redesigned road bike gearing. With X-Range™ technology:

  • Wider gear range and smaller gear steps are offered together.

  • 13-tooth gap rule ensures front shifts are always precise and fast .

  • The 48/35T combination works perfectly with RED cassettes like 10-28 or 10-33, helping you find the right gear at all times.

2️⃣ Integrated Quarq Power Meter (Spider-Based) ⚙️

The SRAM RED E1 crankset provides both lightness and precision by integrating the power meter directly into the chainrings .

3️⃣ DUB™ Technology 🔩

SRAM's revolutionary DUB (Durable Unified Bottom Bracket) technology redefines the relationship between the crank spindle and bottom bracket .

  • Single spindle, all standards: The 28.99 mm diameter spindle works with all DUB-compatible bottom brackets.

  • Improved sealing: Superior protection against external elements.

  • Simpler, more durable: Reduced number of components, increased reliability.

4️⃣ AXS™ Ecosystem 📱

The RED E1 crankset is part of SRAM's wireless AXS platform .

  • AXS App: Battery status, component behavior, personalization, and updates.

  • Connectivity: Data transfer to all compatible cycling computers via Bluetooth Low Energy and ANT+.

  • Personalization: Shift speeds and button assignments.

5️⃣ Hollow Carbon Construction (Exogram) ⚖️

SRAM's patented Exogram technology, by hollowing out the carbon crank arms, offers maximum stiffness-to-weight ratio. The new E1 generation further advances this technology, achieving a 29-gram lighter structure .


🔄 Compatibility Information

⚙️ Crank Arm Length Selection: Why 165 mm?

165 mm crank arm length is ideal, especially for:

  • Those who prefer pedaling at a higher cadence

  • Those who desire a narrower pedaling angle

  • Shorter riders or those with shorter inseams

  • Time trial (TT) and triathlon riders

A shorter crank provides more ground clearance in corners and a more aerodynamic riding position.
