trp spykes or spyres

i posted before but haven't done the upgrade yet because i got confused by the bike shop who said trp spykes do not exist. he said "it's spyres not spykes". now i see they both exist but dont know which on will fit on my '18 radcity. also are these "flat mount"? thanks! 650M on my bike. only drove to work once in the past 5 weeks! :)

Spyres are for road bikes and Spykes are for mountain bikes from the research I did (they have different actuation methods). You want Spykes.
