Santa Cruz Blur 4 C Eagle 90 TR Complete Mountain Bike 2026

Product Details

Key Features

Carbon C Frame– A minimal weight gain of approximately 250 - 280 grams (0.6 lbs) for the C frame over the CC due to the different grade of carbon used. Whether you´re riding a carbon CC or C frame, you get exactly the same legendary strength and stiffness because Santa Cruz uses exactly the same manufacturing facility and techniques.

Travel– 120mm Front / 115mm Rear

Wheel Size– 29"

Superlight™ Suspension– Cross-country racing isn´t a power lap around the park anymore. The courses are challenging and the competition fierce. Superlight™ provides traction to avoid the wobblers but keeps overall weight down. By reducing the amount of moving parts, bearings and linkages, Santa Cruz save up to 289g over previous models.

Specs

• Biking Type: Mountain More

  Biking Type

  
  
  MountainMountain bikes are built for tackling rough terrain with frames made of durable materials like aluminum or carbon fiber, ensuring stability and maneuverability. They feature suspension to absorb impacts from rocks, roots, and drops, providing a smoother ride.
  
  
  
• Used For: Cross Country More

  Used For

  
  
  Cross CountryWith speed and pedaling efficiency in mind, cross country (XC) bikes are the lightest mountain bikes with the least suspension travel (typically 0 - 120mm).
  
  
  
• Suspension: Full Suspension More

  Suspension

  
  
  Full SuspensionEngineered to tackle the most challenging terrain with enhanced comfort and control. Unlike hardtail bikes, full suspension bikes feature both front and rear suspension systems that allow the wheels to move independently from the frame.
  
  
  
• Frame Material: Carbon More

  Frame Material

  
  
  CarbonCarbon is a composite frame material. Unlike metals, carbon is composed of fibrous strands woven into a grid and bonded with epoxy. Carbon is favored by many for its lightness and stiffness but its complexity in fabrication makes it the most expensive option.
