Riderx, I looked at your website and--first, let me congratulate you on its fine looks and setup! Well done.
But on the whole I felt pretty confused and intimidated by it all, which I halfway expected....
Maybe I'll do as Hog Wild thought of doing, and just try riding here and there without shifting gears for a while. If I defer the repairs to my mountain bike much longer, I'm only going to have one gear left anyway!
I guess I have been thinking, "Kids used to ride single-speed bikes as a matter of course." (My own first one was single-speed, in fact. I don't remember much about it, but I don't recall feeling limited. And I'm sure it weighed more than either of my curent bikes!)
That thought made the notion seem feasible, and add to that the clean-looking beauty of a single-speed bike, and the idea started getting increasingly attractive. Plus less maintenance!
So I'm still toying with that fantasy.
