Very Quick Wrench Question

The other option, if you use the drops alot, is a TT style brake lever. I use this set-up and really like it. I ride my fixed mostly on out-of-town country roads though, and use my front brake for desents. The dinky ones you mentioned (BMX levers), mounted on the flats,might be more suited to city cycling (IMHO).

Wow, very cool.
