I commute on a Single Speed (SS) bike about 13mi round trip. Going home is not a problem as the gradients are low and I can climb them. However, going in to work the gradients are much steeper and I have a hard time climbing them. I usually need to stop and walk a bit. I am looking for any pointers on climbing hills on an SS. Thanks
Edit: I am not really looking for ways to avoid hurting myself, I am young and fit so that isn't my biggest concern. I am more concerned with making my pedaling technique more efficient, especially for hill climbs. Another point I should mention is that I am using clipless pedals to increase my power output.
Verdict: I added this because I can only choose one best answer. I think that @GuyZee best addressed my question about technique, but @Steven offered a great deal of help with regards to getting a better mechanical advantage. Thanks to both of you for providing great answers.
