There is only one problem with Cannondale, it is Parts specific, meaning that only cannondale parts will work with it especially for that front fork. Congrats for taking that other one back but now you have another smaller problem: Yes the frame can handle the jumps you throw at it as it is but the fork replacement will cost you around $500 or better, nearly twice what you paid for the bike anyway. Stop buying bikes so fast next time and take your time and ask us please and pick a few and let us help you decide what would suit you best. There is nothing wrong with this bike and you have a good one here you just dont have anything to absorb that pedal bob you get out of a hardtail and that is what you get from a hardtail...chain smacks around and does not maintain tension properly. Next time look at GT bikes (I have a Sanction 1.0 it is a bit pricey for you probably but compare the two please spec wise - both made by Pacific cycle) and you wont have the problem with Canondale specific parts . I work in a shop and we have to order all parts for C dale that come in as we have nothing in the shop and no one wants to go down the street and deal with the Cdale dealer 1/2 mile away because theyre too expensive.... Remember, YOU are the suspension on this bike!
