Really guys-I don't get it. It just seems like im shifting one extra time with this bike. There has been more than once on the freeway where I try to shift into the next gear when I'm already in 6th! I thought about changing the sprocket to lower the RPM's but then I lose power. I just don't understand why they would put a 6-speed transmission in it that seems pretty useless. I should also mention that I do a fair amount of freeway and plan on riding this bike cross-country.
