Last year I bought a redline conquest. I wanted something faster than a mountain bike but sturdy enough to handle a hard packed dirt trail or two.
A few weeks ago I was riding around at a snails pace with my 11 year old son in a school parking lot (I know not exactly the intended use but ...) . He decided we should make a sudden change of direction. I turned, but not sharp enough and hit a 4 inch curb straight on at maybe 3-5 mph. I tumbled off without a scratch, got up and took a look at the bike and saw nothing. But after a few more gentle rides I noticed that the frame is buckling on the underside near the front. I'm devastated. I've never spent over $400 on a bike, so this bike was big money for me and I adored it.
I noticed in the warranty papers that it says that if the frame is bent, the warranty is void. My question is, should it have gotten bent this easily? Is it to be expected that it would crumple in a low speed collision with a curb? (I weigh about 175 lbs btw.) The wheel is still true, the front fork is unaffected. Shouldn't a bike be designed such that some of the less expensive components yield before the most expensive one? Could it be that the frame was defective and my bumping the curb just brought the defect to light? Has anyone else out there had a low collision with a curb that buckled their frame?
