Is anyone using these? I have an older hybrid that I'm converting into a road touring bike, and it needs a new bottom bracket and could stand to have a fresh cassette after a fair bit of rusting that I only partially solved. I'd like to be able change my chainrings as well, and Nashbar has a crank that's marketed for that very thing (mine are welded to the crank). Their parts work and hold up okay? I'm not looking for Ultegra-level components or shaving weight off it; just decently sturdy parts that work as advertised. It's a $300 hybrid back in '93, so I'm not replacing expensive components though they've served me well. What ya think?
