I am very rough on my bikes. I don't do one thing in particular. Though I don't really do downhill a lot. I have mostly decided on a hart-tail for this reason. I want something very tough but the best quality for the price. I am looking in the 500 range. I have looked at getting the new Cannondale F7 but cannondale rolled back the release date and I cant wait that long. I definitely want disk brakes and shimano components. And I would prefer the front fork to have at least 100mm of travel but I don't really know that much so I would like a little help. I'm tired of wally world bikes that have warped rims after 1 week. What should I look at. Thanks.
