Specialized Roubaix Rear Derailleur Hanger - broke AGAIN !!!! :-(

[GPT]

My friend has been through two hangers in 3 months on his new Roubaix. Pretty appauling job from Specialized. Cheap foreign **** eh!!! Luckily for him the derailleur just dropped due south and was not caught up in the wheel, which could have been very dangerous indeed. Given the critical status of this piece I would have expected the manufacturer to have given a little more consideration to it.

I will not be replacing my Casati with a Specialized any time soon.

Have you experienced broken hangers too, or is my mate just very unlucky?

I just bought a 2011 Robaix Expert. Was on my first easy ride, not hammering at all, and my rear derailluer hanger broke. The part broke inwards and got caught up in my wheel, taking some major chunks out of the frame. The bike was 2 days old, first ride.

I brought the bike back to the shop, and they said they were going to replace the whole bike, or at least the frame. They'll put an aftermarket hanger on, as I certainly don't trust the one they are using.

This bike retails for $3700, and I paid $3500. I'm amazed they would use such a cheap part, but I guess it shouldn't surprise me. Do I have to pay > $5000 these days to get ALL quality parts, or what?

Hangers don't just break by themselves. What are the derailleur limit screw adjustments like?

To be honest with you, I didn't even look. I bought the bike at a reputable shop, and they built the thing 2 days before this happened. The derailluer seemed like it was dialed in, so I just went for a ride. I don't even have the bike now, dropped it back off, and I'm waiting for a new one.

Are you thinking this is the mechanics fault?

I have a 2011 Roubaix DA Pro. Got it the first of November. When the bike was new the rear derailer shifted so poorly I wanted to give the bike back. After the shop made several attempts to adjust it, it was discovered the rear hanger was bent. I've got about 1000 miles on it now and it is shifting perfectly, but after reading the other posts I'm on the way to the garage to ckeck the hanger. This is the first expensive bike I've owned and am disappointed in Specialized.

My friends gear hanger broke on specialised Rockhopper on his second ride for no apparent reason going down a slightly bumpy track. The gear hangers i am told are designed to brake if you hit a rock or crash. The broken metal revealed a grey/white crystalline grain structure, my guess is that it is zinc aluminium die cast material such as used in cap pistols which always seemed to brake off at the trigger. If the oxide impurities are too high it would be weak. The design I suppose is to limit frame warranty claims as the mech coming off in a crash is more likely to mangle the spokes/ wheel rather than brake the frame.

I bent one aluminum hanger (my fault) and straightened it. It was in use for three more years with no issues.

I had a bike delivered that arrived with a poorly aligned aluminum hanger and straightened it. In use for over a year with no issues.

You can buy spare hangers here: http://derailleurhanger.com/

The aluminum hangers are easily deformed and broken by design to save damage to the easily deformed and broken frames manufactured today. Some professional teams substitute steel hangers to improve durability and shifting performance...at the risk of frame damage, of course.

Inspect your hanger often. It's easy to spot a mis-aligned hanger from the saddle.
