Mountain Plumbing

So tell me what is the difference between the mountains of $ 150 Schwinn Schwinn mountain bike Meijer and $ 270?
bike bicycle shop. Both have similar components, gears, brakes, chassis, etc. Am I paying the extra $ 120 for the service? Bike shops are pieces of the bike is better. I know that with the plumbing, for example, you get better parts in a plumbing shop at The Home Depot, even the parts with the same number of model. Does anyone have any bike with an excellent quality.
Schwinn experiment. I have a Schwinn dealer. I would not have a Meijer. Components not are comparable first. This is a different level – a higher level component of the same brand of the bike shop. The frames are made of different materials. The Bicycle Bike Shop are stronger and lighter. Here's the sad part – Meijer and bike store bikes done. Those who sell are cheap! Finally, back at Meijer, a team of strikes all or rotation cycle about 16 years of age who is handy with a screwdriver to mount attempts. If you buy a bike in a bike shop, is to gather and configured properly – period. Support your local bike shop – you can not go wrong with your professional wisdom.
