Finally, Velodrome Shop published its lists of equipment used by the gold medalists at the 2020 UCI Worlds (sorry, I am still not allowed by admins to post URLs).

Here are some historical data from previous events:

N.B. At the 2018 European TCC, Buchli, 2350 watt, reportedly used a 11/128 chain to win the kilometre
P.S. First read: (1) Emma Hinze and Lea Friedrich used the above mentioned 2.0-mm chain, namely KMC X11-SL; (2) All sprint golds were won either on Dugast or Continental Olympic II tyres instead Vittoria; and (3) Look introduced some "Track" version of the Blade Carbon Pedal, designed to be strap-free, however, both Dutch and German teams utilised it with straps.
