I dont remember what my inseam is, but it's short, somewhere around 73 cm. my saddle height from center bb to top of saddle at its "sweet spot" is 67.5 cm
if you're actually having pain, you would be best served by:
- dr. or chiro visit
- stretching those hammies
- professional bike fit, pain + tinkering without a good baseline to start from is a recipe for a summer on the couch
