Rebuilt my 2012 dual air Reba 29er and it's as good as new except when I hold the arch and pull up on the crown I get another millimeter or two of extension. I can feel it the most riding when unweight the front end. Right now Im running equal pressure in the +/-. Tried a little more pressure in the positive with no affect. Ive found that my reba is very picky about the amount of oil in the damper and I'm thinking I may need to add a milliliter or two of 5w oil. Any other ideas, experience with this issue.
