Hi guys, this is my first post here on ride monkey. I am 14 years old and I just bought an Astrix Huckster. It is a single speed crankset and an 8 speed cassette. I ride urban freeride, trails, and a little cross country sometimes. I don't mind the weight of the bike and the challenge because if that, but it isn't geared for climbing at all. I am part of my high schools mountain bike club and the rides will start soon and I need to be able to climb. Should I consider a different cassette or add another gear to the crankset? And what would I be looking at for cost for either of those? Thanks. I also posted this in the freeride and downhill section.
