I just started commuting on my bike to work. It's only about 3 miles from my house to work. Getting there is easy, since it's mostly a slight downhill ride. However on the ride back, it's mostly a gradual climb. I just started riding again, but it really takes a lot out of me. I'm running 46x16 at the moment, and I'm thinking about switching to 46x18 during the week when I'm commuting. I went for a 10 mile ride on mostly flat roads and I was fine.
Is 46x18 noticably easier than 46x16, or should I be looking at a larger chainring?
Now I have the IRO fixed/free flip flop. I have the 16 on the fixed side. I know I need a cog and a lockring, what other parts are involved? What tools do you need to do this yourself?
Now I don't plan to be swapping out my cogs all the time, but I'm going to head to my local bike shop/school and have them help me do it (should I decide to go with the 18).
