Don't mess with those garbage bags

There is a first time for everything and others might learn from this.
Had a weird experience running over one of those black plastic garbage
bags. One was being blown across a road as I passed. The bag got
caught in my drivetrain and ended up inside my rear deraileur and
wrapped itself around my cogs. What happened next was described by my
friend who was pedalling right behind me, witnessing the entire thing.
The plastic pried apart my RD and bent my dropouts to the point of
cracking.
Lesson for me is to not to take those bags for granted (and to be more
generous in braking). I ended up spending for replacement parts.

Why didn't you stop pedaling?

Sorry if I seemed insensitive... I meant to follow it up with "I'm sorry for
your misfortune." But again, were you trying to pedal it out?

Phil,
No worries, no offense taken. I was actually thinking that the bag
would just be squished under my rear wheel without causing any trouble.

Phil,
My friend added that the road was going uphill, I really had to pedal.
Though I didn't think about it then.

Glad you're okay.

Did the derailleur cage actually come apart, dropping the pulleys? Did the
derailleur come all the way around on top of the cassette?

And it probably took all of two turns of the cranks at most to do the
evil deeds...and I'd bet that the pedalling resistance didn't even get
all that high in the process.

I had a similar, but less severe, experience several years ago. I ran
over an empty plastic grocery bag, also being blown across the road.
It wrapped into the gears of my rear wheel, and through the rear
derailer. Fortunately, I stopped before it bent/broke anything, but
it was a pain to untangle. I've learned to avoid them.

How right you are. I didn't even feel anything was wrong until there
was no resistance. It was at that point that the RD fell apart. The
cage was still intact so the rollers/pulleys were still in place, but
the the whole cage was twisted off the main body of the RD. And the RD
itself was twisted out off the dropouts. The parts that interconnect
are all bent out of shape. The dropout was also bent inward and was
cracked at the point it was bent.

I was crossing a 4 lane road when I ran over a carrier bag.
Bag wound itself around the cogs and left me without power as the lights
changed.
Scary "rabbit in the headlights" moment and some frantic "punting" with my
feet ensued.
Nothing got broke but many oily minutes unravelling plastic from the chain
and gears.

Respec' those bags

Speaking of bag stories:

Once when I was a kid in New York during the winter one of the
countless plastic bags stuck in the trees had been filled with water
from rain I presume. It had subsequently frozen, and just as I was
passing beneath the tree with a friend, the bag ripped, and the
odd-shaped block of ice fell and hit him on the shoulder. It would have
been bad news if it hit him in the head!

That happened to me, too. I was cranking against a 20 mph headwind.
The rogue bag was flying left and right and just as I cranked hardest on
the pedal the thing flew into my derailer. It ripped apart the
derailer, bent the dropouts, ovalized the derailer hanger and sent the
chain crashing into the the spokes.

All for a plastic bag. LOL

Replaceable derailer hanger, at least? Or is that new-frame time?

Jasper,
Replaceable derailuer hanger... that, at least, offers some
consolation.

Take a close look at the wheel, too. I have a sneaking suspicion that
you're going to discover a bent spoke.

Ouch, did that and 1 spoke is bent. The alignment is off and will have
to have it fixed too.

Bingo! The bent hanger resulted when the der veered into the spokes
as the bag jammed the chain. That's the other part of why you didn't
feel much happening.
