Would you ride 150mm cranks?

Really interesting to find out more about this -- I've always assumed I'm a 175mm guy because most of my bikes came with those. Then when playing around with singlespeeds, it became clear that shorter cranks are common for that application and have some 170s set aside to fit someday. And then bought a bike with 170mms and didn't notice for the first few rides.

The idea of helping the old knees is very attractive -- will have to try some shorties soon.

It is the knee thing that intrigues me too.

I've found that shorter cranks work well for sitting and spinning, whereas longer cranks feel better for standing while riding where torque is more important.

I run 180's on my singlespeed, 175's on my gravel/mountain bikes, 172.5 on classic road bikes.

This is my personal experience. I know the current trend is to go short and I think a lot of that has to do with full squish bikes and their tendency for pedal strikes.
