50 feet after a water stop I hear this ping-ping-ping sound and I unclip before I fall to find that my rival RD has sheared off and is trying to eat my spokes. At this point, I am not to bend out shape, things fail.

I get back to the LBS to see if what can be done late on a Saturday afternoon only to be told that my frame is no longer safe to ride as the RD put a serious dent in the seatstay. The bike is 17 months old and shot. LBS tells me that the cdale replacement program will hook me up with a supersix for right about 1600 bucks.

Has anybody recently done a frame replacement with cdale? How long should this take? I am doing the deathride on July 11 and I really wanted to/need to complete some training in the next three weeks. LBS also tells me that the SRAM warranty is one year but the website says two years. I am going to push this one and stand firm to get a new RD.

I am interested in any angles people have used to get replacement frames from cdale any cheaper/faster. Any other ideas or thoughts?







Thanks,


Todd

This could get fun..

Thats just a huge bummer.
It especially sucks that a pretty cheap part like a that can mess up your frame.

Best keep those RDs adjusted, folks! If they get caught in your spokes, it can be all over for your frame...

To be fair, a Shimano or Sampy RD would have done the same thing if it got sucked in.

True, but I wasn't shifting when the failure happened. I am fairly certain of this as I was doing a constant tension workout on a 50x23 all day long. The rule of the ride was no shifting.

shoulda kept that dork disc...

Surferbruce

something had to have gotten caught in there.

J.R.A. has many common side effects. Must be careful.

Can you post a larger, more clear pic of your seat stay?

thanks

It wouldn't have helped if he did. Dork disks aren't large enough to protect the spokes from the RD.....they protect them from the chain.

"I am going to push this one and stand firm to get a new RD."


It sounds like the damn RD just broke spontaneously. I think I would see if SRAM would replace it with a Shimano RD.

Reminds me of Audi back in the 1990s...be relentless with CDale and with SRAM...my goal for you: no cash out of pocket.

Is this the "I hate my drivetrain and and want it to die" workout?

I'm not saying that caused the derailleur to explode, but 34x15/16 might be a better choice for general parts longevity.

Thanks. I am still trying to figure out what a "constant tension workout" is with a really easy gear.

To the OP...SRAM's warranty is two years. It is for manufacturer's defects. They are really good with replacements. We had someone get a part overnighted that was a mfg defect warranty loss.

You have no quarrel with Cannondale. If anyone other than you is going to replace this frame, it's SRAM.

Make sure your shop checks availability. It is pretty limited right now. They do keep stock off the dealer site for emergencies, but they will probably need to call Cannondale to make sure a frame in your size is available. They can ship pretty quick if they have what you need.

The Cubs will win the World Series before SRAM replaces that frame.

Um, no. Nothing to do with the dork disc. Anyway, how does a dork disc keep your RD from hitting the FRAME? It would take some egregious misalignment of the RD and even worse adjustment at the derailleur/shifters to drive it into the spokes, and if it hits the frame it's clearly had some kind o catastrophic failure. It's either a material failure of the RD or hanger (much less likely) or an improperly assembled chain that popped under load, got stuck in the RD, and shredded the whole thing.

This was an adjustment issue NOT a der failure.

Sorry about your frame.

Johannes

maybe a really large dork disc?

andr0id

Sorry about your broken stuff... Don't really know much about C'dale or SRAM.

I do get comments when I tell people I have 2 road bikes so that I can have a spare. If you are the type that needs to train regularly for racing or fitness, it's really a good idea. It doesn't have to be nearly as nice as your main rig, grab something off Craig's List or whatever...

jrobe

What - look at the pictures. The metal of the RD is broke in two. What did adjustment have to do with this. It was a defective part.

DrPete 

Wrong. A broken chain pulled through the RD under load will rip apart the RD. I've had it happen once too, and it's not a defective RD that causes it.

tosterbe

Does it place me in good grace since I got the botto Picard pic?

Dr. Pete, I am curious about the chain comment. When we looked at the chain back at the shop, the wench said is was a-ok. If the chain wen't wonky would you have expected there to be visible damage to the chain?

damocles1

The only things under tension in a 50/23 are the chain and r/d. IMO, that's not a derailleur issue, but an operator error.
True, the derailleur probably should not have broken, but the big/big, cross chain combo didn't exactly help the situation. The chain was pulled as thing as it could possibly be and the spring in the r/d was stretched to it's limit for an extended period.
SRAm is not at fault here...
