I am thinking of purchasing a 2008 Intense Spider 29 frameset and I would like some honest feedback. I have looked on these forums and the reviews seem mixed at best. I had not heard of the "flex" issues that some on here apparently think puts this bike in the junk category and others don't feel it's worse than anything else. I would like some honest input. If you just want to dump on Intense or this post please save it for someone else. It sounds as though overall this bike would be fine if not even ideal for the types of trails I ride (upper midwest single track, little to no big drops and nothing that anyone from the mountains would consider much of a hill). I consider myself an XC rider as you can probably guess from description of the trails I ride. Again honest input, good and bad, would be appreciated. Thanks.
