Bought a new mountain bike at a local department store didn't like the first one that I purchased so I took it back and traded up to more expensive bike at the same store. I was really impressed with the new bike it even had disc brakes on the front and seem like it was made with quality parts but not well put together by the assemblers. I took the bike to a LBS and was greated by a very knowledgeable tech. I told him why I brought my new bike in and he said it was not uncommon for them to get numerous new bikes from the local department stores that needed to be thoroughly checked and adjusted. The first thing he mentioned was that the bike I purchased was too large for my height, I am 5'7" and had a 19 frame on my bike. The frame size he recommended was 17" also he preceeded to show me some low end bikes that was on sale and recommended that I take a 17" frame Giant Boulder SE out for a ride no strings attached. Rode the bike for 20-30 minutes and needless to say I am the new owner of a Giant. The build and the ride quality of the bike was 100 times better than the bike I purchased from the local department store. I know everyone can't afford to purchase a bike that costs 250-300 bucks or more but if you are lucky to have a LBS that will let you test drive a low end bike you will be impressed!
