I bike to work so at lunch I headed toward the hills for a ride. I just switched to 42x15 fixed last week, from 42x16 single speed. I have never tackled these hills on anything but my geared bike. Its a 5 or 6 mile ride altogether, with about a mile of solid climbing, interspersed in about 2 miles. Before, when I did it on the geared bike, I would drop down into my granny gear and just spin up the hills. Now I had to power up them. I got up them MUCH faster than before, but I had to stop at the top, or for one, 2/3 of the way up, and then again at the top. It was fantastic. I didn't use my brakes on the downhill sections, instead I resisted so that I didn't go too fast. I loved it. Maybe if I do this 3 times a week my weight will start dropping like I need it to. I can't wait to do it again another day! I'm beat for now though!
To open up some discussion instead of just gloating that I actually *did it*, I'm curious: does anybody have any tips for climbing hills fixed?
