My wife is just starting to get into cycling & we're thinking of participating in a week long ride in June (The Great Ohio Bike Adventure). The problem is that although she enjoys riding the bike, whenever she rides for more that 30 min.'s, the back of her neck begins to hurt & the pain lasts for a couple of days. If we can't get this figured out, the GOBA will be out for this year. Note, she rides a Trek 7100 Hybrid with upright handle bars. We have tried adjusting both seat height & handle bar height, but nothing seems to help.
