I have noticed that many people on this and other sites ask the sales man what products to use and how to maintain thier new bikes.I find this as helpful as asking a doctors receptionist how to stop my but from itching.If you want to know how to clean certain areas of your bike or what products to use,ask the detailer at the bike shop.The same goes for any technical info,ask the mechanic,not the service manager.This way you will eliminate the chance of running into someone who will lead you astray through lack of hands on knowledge.
