Bought new from LBS. Professional fitting. Stock everything.
Rode 13 miles. Fairly flat terrain, a few minor hills.
4 Miles into the ride I was already feeling pain and soreness in my sit bones. 2nd half of the ride was very bad. Coasted a lot and tried not to rest on the saddle too much. Wearing a nice set of padded bike shorts. I expected some discomfort on my first ride out but this seemed a little much. Bike seems to fit in every way. I test rode multiple times. LBS made adjustments based on my measurements, etc... Any recommendations? Or is this just growing pains with a new saddle/bike?
