Okay, I thought learning about shifters and brifters was daunting, I just looked up cables and housing. For the newbie here, what type of cables / housing should I be looking at for my 105's. I want to try this route first as the cable did seem kinked in one spot when I put it together (after fedex got done shipping it across country). HELP on the cables / housing!! Too many choices on ebay. Is there a decent online site I can purchase these and know I am not getting ripped off? I don't mind a fair price for a good product....just don't want to overpay. Thanks
