I don't really understand the statistical significance of the numbers you're going to get, but I've probably seen about 150 bent hangers...

I ask because I am curious how important a replaceable derailleur hanger is on an aluminum road race bike. I'm looking at the Pinarello Galileo, and it doesn't have one. The Cannondale CAAD 5, on the other hand, has one. I know aluminum doesn't like to be bent around, and was wondering how many aluminum road race frames you've seen that had to be trashed, or couldn't be fixed back to new b/c of a bent derailleur hanger. Thanks for the info.

I am a big fan of the replaceable hanger. Recenty went down in a crash and the hanger snapped off. Glad to spend the $10.00 for the new hanger. Without the replaceable hanger, chances are that my Pegoretti would have been ruined.
It's a risk,TJeanloz

Personally, I don't think I'd buy an aluminum race bike without a replaceable hanger. You might never need it, but then again, you might- and I'd much rather spend $10 on a new hanger than $1500 on a new frame. Hangers don't just bend- caught right, they'll snap off clean. I haven't seen very many frames trashed because of this, because the vast majority of aluminum bikes come with replaceable hangers.

What it comes down to is that if on all other counts, it's a tossup between the two bikes, I'd get the one with the replaceable hanger; but the risk isn't so great that I'd buy a bike that I didn't really want just because it had that feature.

I bend them yearly on my mtb - but only once in the last ten years on a road bike.The frame was broken too, so it was a non issue. Replacement hangers are essential if you want the fram to last.

I have bent three on my mountain bike in the last two years, but have never seen one bend on a road bike. My Klein doesn't need a der. hanger because it has rearward facing dropouts. I forget the technical name for that.

Bent mine on my mtb w/ no breakaway. Bent the aluminum back and it's been ok for a while now, but I hope I don't bend it again.

I wouldn't by a bike again w/out a breakaway hanger.

I use a Wreck-defier bolt kit on my Santa Cruz Superlight because it doesn't have a replacable hanger and you do bugger up the rear der. frequently mt. biking. Here's a link to the company that makes it, but it looks like they sold out, I'm not sure if they are making more.

Cambria might have some still (about 2/3 down the page):

I think there are some other options on the market but don't know of any offhand.

I've put breakaway derailleur bolts on a few bikes. I don't know how well they work because I never had one of those come back after the bolt brokeaway. I sure can't say that for replaceable derailleur hangers, some of those seem to be seriously fragile and breakaway awfully easy. I'd also recommend buying one before you need it just to have on hand. You don't want to have to wait a week to 10 days for a special order replacement only to find that it isn't the right one and we'll have to try again.

One big negative for the breakaway derailleur bolts, that's not an easy installation. It generally takes my full vocabulary to get one in right.

replacable hanger, because on the off chance you bend the thing, you can normally bend it back without difficulty. Replacable AL hangers seem flimsy, and more likely to bend and cause problems than a good permanent steel one.

That said, on an aluminum road bike it's probably the way to go, given an otherwise equal choice. But as someone said, I don't think that factor alone would cause me to choose one bike over another I liked better in other respects.

I bent mine on a steel Serotta. No way I could bend it back and have it aligned properly. It was mangled pretty bad and I had to send it back to Serotta for replacement. It was a freak thing though so I can't imagine doing it again - touch wood !
