Lots of things to check here. I'm assuming that you're checking the distance from the top of the fork tube (or cap) to the top of the upper triple, right? If you are, this distance really doesn't me shit relative to the geometry of the bike. For example, you could have one fork tube 3 feet longer than the other, and as long as the extra 3 feet was sticking out the top of the triple, your geometry is fine. What you should check is the distance from the top of the lower triple to the centerline of the front axle. This is a much more accurate representation of what is going on with the geometry. If its the same, its entirely possble that you twisted the tube while you were moving things up and down in the triples. No big deal. If those dimensions are the same, you're
