Hi, I'm new here. I have an old 12 speed Cannondale with down tube shifting. It doesn't shift smoothly (could it be because the bent rear axle?) so I just leave it in one gear (52/13) most of the time unless I come upon a long hill. I want to upgrade my drivetrain to STI, but I still have some questions. I need a new freehub that supports hyperglide cassettes, but there aren't too many of those around for 126mm dropouts. I've found some 126mm hubs on ebay like the HG-20, 105 FH-1051, and Ultegra 600. My main question is how do those hubs compare with each other in terms of quality, durability, and performance? Does the Ultegra have better bearings, seals, and stronger body material? What group in the Shimano family is the HG-20 from? Is it any good at all? I could live with the 105 FH-1051, but does this model support hyperglide cassettes? Are there any third party 126mm hubs that are compatible with hyperglide?

I apologize if my questions seem simple. Thanks.
