All looks quite normal stuff besides the new approaches to softtails.
Evidently, a tubeless tire plug and insertion tool taped to the seatpost is lighter than a Co2 dispenser or a can of aerosol-charged sealant.
It looks like a Scott team bike and if so then it would be fitted with Dugast tyres which do not work with sealant or like CO2 very much as far as I am aware.
Interesting that Absolon is running the continental protection tyres and not the racesport. I also found the racesport carcase useless
Possibly a training setup for test laps? I can’t find a decent pic of the tyres he raced on.
The most interesting thing about the bikes is that despite running all these weight saving bits and bobs, they are very much still at the mercy of their sponsors, evident by seeing all SRAM bike now running RS-1’s!
