lazy / cheap question. Do I really need to do maintenance on these items? It's not like it's cheap, and after three years, they both still air and seem to be working as new. disclaimer: I'm not a big tuning guy, I pretty much set it in the middle, forget about it, and ride. I just can't feel a big difference. If performance deteriorated over time, I'd likely not feel that. I had a reputable wrench tell me that i should wait and just fix it when it breaks. Honestly, I'm a bit concerned that tearing it apart might be detrimental. Along with that train of thought, how does the gang feel about a disassembly of a frame to inspect the frame, bearings, linkages, (and for my yeti bike the switch infinity) torque to specs, etc....(I'm leaning towards the frame maintenance, as having a frame shit the bed is a much more tragic thing.) Thanks is advance!!!
