This morning, as I sit staring at my lovely, new, dual suspension mountain bike, purchased yesterday from my LBS, I'm wondering whether I should get an extra mount so that I can transfer my Edge from my road bike to my mountain bike and back again. Here's the thing. The mountain biking around here can get very, very dusty, and I'm concerned that all the dust could cause some damage to the Edge. I have a Polar cycle computer that I used on my old hardtail and I can use that instead, but I've gotten to really enjoy uploading and analyzing all the data from my Garmin after my road rides. Plus, I can email all the Garmin data to my CTS coach and I can't do that with the Polar.

What do you all think? Might it cause irreparable damage to the Edge?
