I've got quite a few stock wheels in my collection, if it's important to you, I'll weigh a few & give you the highs & lows. Let me know. As for deciding if lighter wheels are worth it, they are. It will absolutly transform your bike, buy the lightest wheels you can afford. If I had the money, the BSTs would be at the top of my list.
