NIce nice I c ic... so there's no "Home Depot do it yourself" way. I was curious because stupid LBS can charge you like $20 for allen wrenches when you can get the same freaking thing at Home Depot for fraction of the price. I just want to know in advance like.. if I rip a tooth out from one of the gears, how will i able to take it out. so yea.. thanks for all the info!
