Bluebiker, sorry I wasted your time and or the site bandwidth. Seemed like a simple ? that many guys into these bikes may know off the top of there heads. It probably took you longer to type your post than the answer would have, if you know the answer. I did take a quick look at the tech section, and didn't see anything, but thanks for your response. Also just took a quick look at the link/manual you posted, and didn't see the answer, not saying it's not there though.
