I don't think there's any way to ride up the hills I climb without sweating. The Losethecar web site suggests going slowly. I do that, not that I have a choice. It suggests stopping if I start to warm up and sweat. That would be frequently, near constantly. My Fargo goes down to 18 gear inches and that's what I use climbing. It's a lot easier for me to just get to my bus stop a few minutes early, cool down, and put on a dry shirt I brought. I don't need a shower before work, but I change my shirt before getting on the bus, and change pants when I get to work. Luckily I don't stink when I get sweaty, I have no idea why. I do sweat a lot but wipe it off with my shirt.
Having said all that, I rarely hammer it when I ride. I imagine I'm in touring mode, cruising along at a comfortable pace, which for me includes getting sweaty in any weather. I guess I average 15 mph but that's partly because I don't use my brakes going down those hills I climb so slowly. I don't have a speedometer on my bike but I know the distance and I know how long it takes me to ride it.
