When I rode the GAP Trail last year, it rained two of the three days. I had my Road Morph G mounted on the downtube next to the water bottle cage using the Topeak accessory that Skydog 75 cited. When I got home, I realized that the interior of the pump was contaminated with crushed limestone chips and water from the ride, the amount of which was truly surprising to me. It would have ruined the seals in short order if I hadn't caught it. I like where Mr. Beanz mounted his pump on the seat tube. I'll have to give that a try.
