I tried some 155mm cranks on one bike of mine, and interestingly, I like them just fine.
I'm 5'5" and 29" inseam. I ride 165 mm on Tri A and ProTour that have Shimano Hollowtech II on them - R7000 has a 160 mm available, but nothing short.
The Ironman has Shimano 600 crankset with also 165 mm.
Recently I have some discomfort on my right knee, and since this was a cheap find I am giving it a try.
Probably will try on Sunday, after my double century-ish (short) this Friday Saturday riding my TriA.
