Over the past few weeks I bought a low end high end (that's what I call it) Felt mountain bike. It retailed at about $700. I bought it used for $200 and it was in like new condition. I wanted to put some better parts on it so I upgraded the following components: installed hydraulic disc brakes, upgraded suspension fork, pedals, headset, grips, tires, chainring, rear cassette and crankset. I fully tuned it and also converted it from a 3 x 8 drivetrain to a 1 x 8 drivetrain. This eliminated the front derailleur. It went from 33lbs to 29lbs and now it is a pretty respectable mountain bike. I enjoyed this product and I feel thankful to have a nice bike.
