I'm like 1 cm taller than you and the pain is real.

And pants are still kind of doable, but mountain bikes? My enduro rig is size XS on 27.5 rims and with manufacturers dropping 27.5ers I expect this to be the last bike that feels anywhere close to "nimble". Also RIP women riders, but that's been the case for years now.

I also have proportionally small feet (size 39 EU but wide as fuck, so I only wear expensive minimalist shoes with wide toe boxes) and small hands (RIP piano, I'm not hitting an octave ever).
