so today i did an exreriment. i put my front brakes back on for the first time in like a year just to see if my riding improved. well, turns out i ride better without them, even front wheel tricks. so i checked out my back brake system and thought "what a sorry piece of crap from hell" so i revamped it. i threw out my sst oryg, cuz whats the point of my dragonfly cable if i have an oryg on the bottom section??? so i put on 2 slic cables running next 2 eachother and left out the bridge cable and just crossed them into the arm bolts. then i went & got some brake pads, and bought some of the weirdest brake pads i have ever seen. they are like half the weight, have only 1 spacer and its like a half millimeter thick, and a hex bolt going into the pad itself. turns out ty\hey are perfectly shaped to my rear rim so no setting is neccessary. they have the stopping power of close to a flippen disc brake. i have never had such amazing braking on a bike with a gyro before. i couldn't believe it. i have a couple questions now having said all that:
1. is that dual slic cables to the rear called a london mod? if not, whats a london mod?
2. am i better off if i ride better with no front brakes or is it entirely prefrence?
3. and totally off the topic, how strong are cf stem spacers?
any responses would be greatly appreciated.
