I have a relatively new PT wheel from PSIMET (yay). I have the Mt Greylock (MA) Century tomorrow, which is 100 mi (obv), and 10k ft climbing. I really wanted to get the data for this ride, but now it appears that I will be riding in the rain for at least part of the time. Question: I have heard of PowerTap hubs (this is a Pro+, with Garmin Edge 500 head) being problematic in the wet. Is this a big risk to my new wheel? What would you do?
