(ignore the break/brake typo, thanks)
Hello. I'm pretty new to fixed gear riding. I bought a cheap bike off of craigslist that had mostly new parts but a used shimano front brake. I don't know very much about bikes so I can't tell if the brake is good or not. I've ridden some bikes before where as soon as you tap the brake you stop almost instantly. My front brake slows me down to a stop pretty well, but its definitely not super fast and there is no way I'm going over the handle bars. I have a really steep geering 44x14 right now (came like that.. and I didn't know better), so I think that is making it harder to stop, but I plan to go down to a 44x17 (and then adjust the chainring size as needed. does this seem like a good budget concious strategy?).
I'm going to be biking primarily in Boston, so I want to be as safe as can be. I'm basically just wondering how fast that front brake should stop me if I'm going at a good urban/city pace.
Thanks for your help!
