Basically I need to re-gear my bike.... How?
Background story: In 2010 when I worked four miles from home I looked on Craigslist for a bike, there was nothing but beachcruisers, fixies and 3500 dollar race bikes. I checked out the bike stores and they were just as bad. I ended up buying the Tour De France Polka Dot Jersey seen in the picture above, online. Its manufactured by cycle force group and when not broken is quite enjoyable.
The point: The bike is made for hill climbing and is very good at that, however with all my might pedaling downhill I could not exceed 31mph. For lack of a better expression I was redlining my legs, I could not pedal any faster.
My job is farther away and so is everything really, from where I live now, but I feel like I would use the bike more if I could get an extra 15mph out of it. Am I asking to much? If not, how can I change my ratios in a way that wouldn't justify buying a new bike?
