Rolling Resistance (Crr) Reference

Below are typical Crr values for common road conditions and tire types, for reference only. Actual values may vary due to tire pressure, road surface material and condition, tire model, and other factors.

Surface / Tire Type Typical Crr Value Notes
Professional Track / High-performance Tubular or Tubeless (23-25mm) 0.0025 - 0.0035 Very low rolling resistance, ideal conditions
Quality Asphalt / Road Bike Clincher (25-28mm) 0.0035 - 0.0050 Common good paved surfaces
Regular Asphalt / Road Bike Clincher (28-32mm) 0.0050 - 0.0070 General urban roads
Rough Asphalt / Endurance Road Tires (30-35mm) 0.0060 - 0.0080 Poorly maintained roads
Gravel (Hard-packed dirt/gravel) / Gravel-specific tires (35-45mm) 0.0070 - 0.0120 Unpaved surfaces, varies greatly
Mountain Bike Hardtail / XC Tires (dry hard soil) 0.0080 - 0.0150 Off-road conditions
Regular Commuter Bike / City Tires 0.0060 - 0.0100 Mixed road conditions
Tip: Lower Crr values mean lower rolling resistance. Tubeless tires and latex inner tubes typically have lower rolling resistance than butyl inner tubes.
