Thanks for the kind offer. Everything checks out o.k. The rear hub is fine. It's an old XTR 8 speed with the Ti casette. I expect the bottom bracket will fail but I believe it's a run of the mill un54 which costs next to nothing. I'll stick to my old parts. It's 8 speed xt rapidfires with xt front xtr rear derailluir. It's has the origanol rock shock that I added coil springs to when it was new. It's a Stump Jumper pro in the mountain dew color.
