What I have is a Diamondback Sorrento DX which was bought new in 98ish, has components that didn't come on Sorrentos untill 99 or 2000 and the DX was only made in '96. So I don't know exactly what year it is. Any way, it was barely ridden for years and then I rode it a few times 4 years ago but THIS summer I have been all over it. I have no where NEAR the miles on it that some of you guys do and I basically suck off road but I'm plugging away at it and I ride it on streets and trails. There is nothing wrong with it other than it's old. It functions flawlessly. However, because I have had it for so long it has taken on a sentimental roll as "my bike" and I would hate to see it get beat to hell or even broken as I try harder things on the trails. There are a few things that I would like to upgrade on it like the stem and bars and shock and the wheels if and when I bend them but other than that it functions as it should and I enjoy it. At the end of NEXT summer, if I keep with this, I anticipate getting myself a dual-suspension XC bike.
So, other than my sentimental attachment to her (and disc breaks that I don't think that I would pay for), is there a reason to up-grade this 10+ year old hard-tail for a more modern design?
