Look, for the final time, there is absolutely nothing wrong with 105 compared with Ultegra. Those who say they can tell the difference are bull shooting. I have used both and I can say with complete confidence that that I would buy 105 every time. We as mere mortals will not wear it out, it functions every bit as good as Ultegra (and Dura Ace for that matter). Please understand that manufacturers produce tiered kit to pander to the the equipment freaks. If you are chasing golds at the Olympics or are trying to outsprint Cav, then by all means spend your loot (or persuade your sponsors to spend). But if you are a regular cyclist, save you cash for other items.
