Riding today and my read derailleur hanger explodes and the derailleur gets stuck in my spokes. How common is this?
A little background...
I bought a KHS alite 500 in February. First bike I have owned in over ten years. I didn't do much research before purchasing but I went to a LBS and it was the best out of what I tried that day. I rode it fairly often the first few weeks, but always on paved trails or in the neighborhood. Then about two months ago I bought a trailer to pull my daughter around the neighborhood and have ridden nearly every day since.
So my first question is could the added weight from pulling a trailer up neighborhood hills (lots of shifting) every day for two months stressed out the hanger? OR, how about the fact that I fell over twice yesterday, on that side of the bike. Twice. I've had my SPDs for three months and never fell, but for some reason yesterday I was a jackass with no coordination.
I've read plenty of times that you should keep a spare hanger on hand, but I always assumed this was for rough trail riding and not for a guy stuck in the neighborhood.
