Donk – What do you mean by chainring “switches”?
front gear shifts? or chainring replacement?
dunno about you but I can ride everything other than sustained/steep climbs in the 36T so only really drop to the 22T for seated climbing (more so when I’m fcked). I only run an 11-28 8 speed cassette on my “XC” bike and am pretty unfit (but fairly strong).
if you mean replacing from wear, I’ve never morn out a steel 22T ring quicker than the 36T alloy one
