A freind of mine rides a full suspension Klein Adept Race. He often complains of pretty significant back pain when he rides. We have noticed a few trends. His pain happens more at this one trail we ride that has some pretty steep and continuous uphills. His pain is less on the Klein Palamino that he is demoing which leads us to seating position.
We have already gotten a new seat which improved but did not eliminate his pain. He most mentioned that the difference in the bikes is most notable is the Palamino feels as if he is pulled in a bit too much for comfort between the seat and the handlebars. We suspect from this that he might be leaned over too far on the adept and that combined with leaning over to climb long/steep hills is just working his back. Our thoughts were to get a shorter/higher rise stem or riser bars.
Are we barking up the right tree? Is there a different place or component of the bike we should focus on first?
