Velopedia analysis
What the specifications mean
The record establishes rear suspension without confirming a suspension fork, making shock condition and pivot play the relevant suspension checks. Carbon construction changes the inspection emphasis from metal-style dents and corrosion to impact damage, ripples and overtightened clamp areas. The published ML - 2.40 kg / 5.3 lbs weight is a reference for the documented build; frame size, pedals, tire setup and production substitutions can change an actual scale reading.
Suspension setup
Rear only documented
The archived record establishes rear suspension but does not establish a suspension fork.
Frame material
Carbon / composite
Look for impact damage and clamp marks rather than metal-style dents or rust.
Published weight
