I had a rather nasty wipeout due to black ice today on my fixie.

My front brake arm is bent, and my left lever is at a 90 degree angle. The lever isn't an issue for me as I was going to switch my brake set up to my right lever being the front brake anyway...

I was just going to start running a front brake only on my fixie, too, as I'm getting more confident.

Which brings me to my next point. Are there any reasons not to use the brake arm assembly from my back brake and use it on my front? I don't know if there are, but I want to be sure as I'm not completely confident going brakeless yet.
