Went for a lovely 6 hour ride on 6/17/2025. After the ride, my back was sore between my shoulders. Wondering if has happened to anyone else? Also wondering if maybe handle bar riser would help? I try to sit straight, but I find that I am putting downward pressure on my handle bars. Is this normal and I am just weak? I also noticed to try and square my shoulders I have to sit way forward on the seat?
