I can always strip 10lbs off my bike fairly quickly if I want to ride a lighter one. Problem is, the stuff that's on there is stuff I feel like I *need* on there. For instance, even though I have relatively flatproof tires, I still carry a patch kit, spare tube, levers, and a pump. Kinda the old "belt & suspenders" thing I guess.

I hate not being prepared to handle at least the most likely problems, so even if I had a sub-18lb technobike I'd still feel naked riding more than a few blocks from my house (basically, walking distance) without some of the stuff.

I *have* stripped all the extra stuff off and ridden the bike, and it's fun, but I was nervous until I got home. Besides, I ride for fun and fitness, and a heavier bike is actually better for fitness riding IMO.

As for group rides? I'm too slow and too much of a curmudgeon to ride with other people.
