My mountain bike racing days taught me real fast that you always have spares. In MTBing it's not uncommon to break them a couple times a year.

This can also happen very easy in the transition zone.
Had my bike racked pre-race, wind gust knocked a few over, mine landed on its drive side, hanger bent in..
I too carry a Wheels Mfg spare to races now.

Just wondering, Will a shop ever take a hangar off an existing in-stock bike in a pinch to help a guy out for a race and just order a new hangar? I would imagine TM01's don't exactly fly off the shelves everyday.

User error. Bike manufacturers can be blamed for plenty, but this is not one of them.

From what you write I take it that you did not check that the derailleurs worked properly after you unloaded/reassembled the bike (from your account it sounds that you bent the hanger while transporting it in your vehicle).

Checking them to operate cleanly through the whole gear range after man-handling/transporting the bike is not BMC's responsibility.

I think you learned an expensive and painful lesson...

Disclaimer: I don't own a BMC and don't care for them for a variety of reasons.

One did offer to take one off a bike but by the time they called me I had packed up the trailer and was 3-hours away and 4pm the day before the race.

Where did I blame BMC? It was a warning for others to be prudent and order a spare for their bike.

Look provides a spare and it would be good practice for others to follow suit.

i just ordered another hanger.

thanks

I would say that would be highly dependent on who the customer is....ie. someone who spends a ton of money at the bike shop? OK, maybe not a ton, but buys their bikes from said bike shop? Then maybe. But a stranger to the shop? I wouldn't count on it, and if they do, I'd show up with a case of beer for them. My .02.

so true.....the moral of the story is to identify a bikes said weakness before it becomes an issue, and implement controls.

"I would definitely smell her seat after a century ride"

I want to know how you busted a derailleur hanger so darn thick and short?






I just can't imagine it bending or breaking that easily.

It might have been bent slightly while it was boxed during travel. Got caught in the spokes in the large rear cog and snapped like a twig as the holes for the 2 fasteners provides a shear failure plane failure despite the thickness of what seems to be aluminum.

Like others have said this prevents damaging the frame.

Damn, that sucks. I guess if the force is rough enough it'll give but damn I just want to know what did it. Derailleur hangers need to be redesigned to handle tougher situations.

Better order a few for cheap insurance.

These guys were great!!

Yes you are lucky I had to get an entire new bike because my dropout broke off instead of the $20 hanger. Not a BMC, but same type of problem.

My derailleur hanger story:

36 miles into riding the Blue Ridge Parkway on a 5 day trip, I somehow ripped off my rear deraileur, breaking the hanger. A carbon fiber Lapierre was not going to be easy to find a part for. I made a single speed, since I always carry a chain breaker and power link. Seems I missed the natural chain line by 1 cog. Every 1/3 of a mile or so, the bike would shift up a cog and the chain would be too tight to ride, so I would have to stop, loosen the wheel, drop the chain one cog. We rode for another 50 miles, 30 miles on the Blue Ridge and 20 miles off, stopping every 1/3 of a mile, to get to a mountain bike shop. I was about to buy a cross bike and ship my bike home, figuring I needed a cross bike anyways. Guy had told me there was no way he had that part, but went to look. I had settled on the bike to buy when the guy came back. He had the part. Somebody had ordered it for a Bianchi repair a while back and never came to get it. I told him he had no idea how sexy he looked at that moment. He replaced the hanger, the chain and the cable, and $147 later I was out the door. We finished the trip. I always carry a spare now. It is the only time I have ever needed it.

This definitely sounds like you are blaming the derailleur hanger for your DNS, when it is entirely your fault for either bending it during transport and not inspecting it before riding, or for not having your RD adjusted property.

The warning is for others to maintain, adjust and inspect their bikes before riding, especially after transporting and/or big races.

.

Ornery comment.

If you don't know it could be a problem how do you inspect for it? Kind of like code.

Sigh....

Is it not common to remove the rear derailleur when boxing up a bike? I do this on the rare occasion I fly with a bike to ensure my hanger doesn't get smashed in transit.

Kind of like Cervelo's tri bikes, eh?

I always remove the rear mech when flying. It's not rocket science. I've seen people not do it and have problems.

Thanks for the "warning" though - you've reminded me to order a spare for my race bike.

Yep, for sure. But dérailleur hanger is a separate piece that screws on to the frame and is designed to break on impact to save the frame from damage. You would have to unscrew this piece as well or at least carry a spare to make sure you're not scrambling last minute.

Broken hanger + horizontal drop outs = race single speed and HTFU.

You're a horrible person for having any kind of problem. You should be ashamed for existing. Criticizing you without cause is how some people make themselves feel smarter.

Anyway, where's a good place to order a replacement hanger for a 2013 TMO2?
