Current selected tyre/powermeter descriptions align at their stated scope; fitted 26/28 mm tyres remain distinct from the 32 mm UK maximum. UK fork material and gross-mass observations do not determine package weight. Mainland China configuration, stock, checkout and warranty eligibility remain unresolved.
