I dunno about the importance of the back brake. It's good in rain, but otherwise it's good for causing the arse end of your bike to slide out from under you. I run only the front on my geared bike, and was planning to put just a front brake on the fix I'm putting together this winter. Can anyone tell me why that'd be a bad idea?
Ps I'm not even going near any suicide hubs- I like my pants and would prefer to keep them un-shat in.
