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. Mixed frame construction calls for composite impact checks at carbon sections and dent or crack inspection at metal joints. The published M - 2.50 kg / 5.52 lbs weight is a reference for the documented build; frame size, pedals, tire setup and production substitutions can change an actual scale reading.
