If in 8 months you're at 80 miles a week, you are already an addict. You think it'll stop here??? And you only have one bike??? What if it gets sick???

Save the pesos while you ride and consider *exactly* what you want in your next bike. (What's going to happen eight months after you get it??

Here's an idea: buy your new bike, then find somebody who needs to upgrade to yours and either sell it or trade it for something a little less nice for jus' ridin' around (or riding with slower groups when you want to work a little) or to put an Xtracycle on or something )
