A builder's post (30 September 2026) reports a silver size-L R7170 build and a black-gold size-XS R7120 build each just under 8 kg; these were custom-assembled builds, so the weights are community reports rather than package specifications.

攻（KUNG）JD price index: MACH, MACH X, HORIZON and FEO listings
Public JD index of 攻（KUNG）flagship-store listings. Titles name MACH-马赫 aero complete bikes with Shimano 105 R7120 and 105 Di2 R7170, MACH framesets with the DA5*5 integrated bar, a MACH X 马赫X all-round lightweight complete bike with Shimano Ultegra Di2, HORIZON 天际 complete bikes and framesets, HORIZON-FEO DISC builds and an entry FEO DISC bike. The index shows no prices, and a direct mobile item page on 24 October hid the price behind login, so no JD price is recorded.
