After reading many times that the most noticeable improvement will be found with better tires and wheels, I bought Continental GP5000 tires and Vittoria latex tubes, and the difference was very noticeable and substantially enhanced my enjoyment of this bike. I am now looking at wheelsets and I think the set I want is the Hunt SL disc wheelset. I am not mechanically inclined and will have a mechanic install them but before I buy them, I want to ask a question from this board. It sounds to me as though the primary attribute that will provide a more enjoyable ride is the lighter weight. I am unable to obtain reliable information about the weight of the factory Giant SR-2 Disc wheelset from Giant itself, but various comments I have seen online from users list it at somewhere between 2000 and 2500 grams. The Hunt set is listed at 1448g, so the savings is at least 500g and perhaps more. This sounds like a lot to me and should be an improvement I can feel while riding, and to me is an amount of money that is worth it as long as the difference is more than minimal. Any thoughts?
