Right now I am riding a 2008 Raleigh Mojave 2.0 which I see now was a bad decision.... really should have coughed up some more money. I considered upgrading on this frame however I don't think this would be a good investment. I feel like the place that I am hindered the most is hill climbs, when I hit some root shelves I have to walk the bike. Thought about some more aggressive tires..... right now there is some Kenda Kwicks on there. Have the triangle pattern down the middle with some side knobs. Is this bike worth upgrading at all and if not what is the best hardtail 29er thats good at climbing for the price... try to keep it under a grand or at least not much over it.
