As most set-ups will have ROUGHLY 10 inches of wheel travel whether itís long travel or standard travel. Whatís really changing is the shock length and the shock shaft length. But this is done with changing the position on the a-arm mount, not on the frame. I say save your money and run the frame you have until it can no longer be financially viable to repair. Your biggest hold back of a stock frame is the rear linkage. Itís progression rate is not very desirable. Iíd recommend a no-link frame for XC. Not just for itís ground clearance advance, but it has a fixed leverage ratio. Im running a stock frame with a custom linkage and swing arm next year.
    This is the best advise hands down . Stock frames work fine. i run one on my XC bike. Long Travel is a gimmick. and dont spend extra money on a cr500 link unless you want to be really serious about racing. No links are better than a standard 250r link and there are options to convert your stock frame to a no link. Check out ISF racing if you want to go no link.

    The reason narrow front is better is because of the reduction in bump steer. the pivot point of the a arm is nearly the same as the tie rod end. Narrow front end is just as significant of an improvement if you are a serious racer. Also i run a no link with a stock air box. Im not sure why everyone has so much issues.

    I think I'll try this stock gusseted frame and see how it holds!
