You know how motorcycles have crash bars, usually there to protect the body of the bike, not the rider?

Do they have something like that for bicycles, like for falling down? I'd like to have one on my right rear to protect the rear derailleur if I fall down.

If so, where can I find one?

A lot of talk about crashing lately.

I remember some really inexpensive bikes having some framework that stuck 1-2 inches outside the derailleur to protect it if the bike was dropped on its drive side. However, I haven't seen anything similar for anything but the cheapest X-Mart bikes made a couple years ago.

The only way I really know how to protect the derailleur is to dump it entirely, and get a Rohloff hub.

Get a shimano xt shadow RD. It sticks up behind the cassette. It is kinda neat.

I've got a couple of them lying around in my bike stuff, somewhere. If you can't track one down, PM me and I'll send one to you.

I think that's one of those things that sounds like a better idea than it really is. I've bent a bunch of those back because they wouldn t let the derailleur access the smaller rear cogs anymore. If you don't have one you might have to bend the derailleur hanger back. It's about the same amount of work either way.
