Thanks for the advice! The reason i was so interested in Bmx sidepulls is because they are easily available under 15 bucks, and the quality is pretty good; they certainly are not going to break easily. That is why i was hoping to get a pair rather than low budget road brakes for twice the price (the range of prices for bike components bmx vs road or xc is an interesting, however different discussion that might tease out some sociology and economics).
I was thinking that if i were to get the bmx sidepulls, i could just space the pads to accomodate for the rim size. Has anyone tried this? Due to my affinity for endos on my beater roadie at stoplights, i have a bad habit of breaking cable-ends; am i wrong in thinking that bmx cables will be a bit tougher?
As to beater bikes being bad, my beater bike is great, but i want it to be minimal investment because its a bike i will leave locked up outside all the time, giving it a high probability of being stolen.
