When up shifting like a sane normal person the synchro rings are not working that hard. They are simply acting as a brake to bring the gear train to the same speed as the slider is spinning. It's down shifting that makes them work. Of course when speed ,and power, shifting all bets are off. You are hammering the synchros quite hard. It sure is fun though.
