Is my bike ruined?

godtabh

Out for a spin this morning.

Heard a big bang behind me. Looked down and the rear derailuer was hanging off. Not sure what happened. Riding a long and it looks like the chain jumped, got caught and sheared off the derailuer.

In that process it looks like it hit of the the seatstay and chainstay. It doest appear to be cracked but there does appear to be layers missing. I'm hopping its only paint. Will bring it to the LBS before work

Any come back here with Ribble? Bike is less than 2 month old with about 100km on it

Looks like your rear derailleur shifted into the spokes. Limit screws badly adjusted. You probably just need a new derailleur and hanger. Frame damage looks cosmetic but the first picture is a bit unclear

I'd take clearer pictures (use a flash ir take them outside) and send them to Ribble and ask them what they can do. They're very good to deal with. Explain that the gears were working 100% and shifting fine. It'll do no harm and they may cough up for a new frame.

Should I hold off bringing it that lbs then? Might at least ask them to sort the wheel so at least I can be on another bike

What gear were you in at time?

Were you in middle of shifting front derailleur?

I don't think I was shifting at the time. Also not 100% sure what gear I was in but high enough in the block

If the stay is cracked then you can likely get it repaired.

I would email them first and foremost. If the gears were performing faultlessly and no one made any recent adjustments to them then there was possibly a fault with the rear hanger. They'll get back to you fairly quickly. If you have someone else messing at the bike before they make a decision it may invalidate any warranty you have (and I'm sure there must some form of warranty with the bike)

Looking at the hanger it is very thin. Wouldn't much stiffness in that and must have flexed into the wheel

Odd that a jockey wheel is missing - unless you removed this yourself?

Otherwise I'd say it's a possibility that the jockey wheel sheared off, inner mech cage then grabbed onto the spokes and dragged the entire assembly backwards and upwards.

Not nice. I've found the warranty department with Ribble a little hit and miss, but mostly alright. I had to send a seatpost back that I got with my build because there was a flaw in the carbon and when doing so asked if they would exchange for wider bars after I inadvertently ordered a size narrower than I had on my other bike. Was told there would be no problem with this only to receive a replacement seatpost back out in the post again. When I queried I was told that actually no, they wouldn't exchange for a different part, because the parts were received as part of a full build. Wouldn't have bothered me if I had been told that first day but I was a little peeved to be told I could to then be told that I couldn't. They'll engage with you though and will generally respond quickly to any queries.

I've put 10,000km on mine in 10 months and have had no problems with the RD hanger in terms of flex or anything else.

godtabh

I didnt remove the jockey wheel and given the darkness when it happened I couldnt find it after.

I've emailed ribble and waiting to hear back.

TBH I'm abit annoyed. The bike has been used 3/4 times. The first time the ribble wheel blew a spoke. That wheel has been returned and being replaced as we speak. Not happy with the quality so far but CS has been good to deal with.

That's the whole point of them. They take the brunt of the energy and break instead of breaking your frame. Once the derailleur arm catches in the spokes, something is going to break. Better it's the piece that costs €8 as opposed to €800

Once the derailleur catches in the spokes, it's getting mangled. I wouldn't read too munch into that

I get the purpose of the hanger but is a flexible hanger causing the issues its meant to solve?

Curious, what gear were you in when it got mangled? I had something similar happen (though on the mtb) where the chain was too slack and swung sufficiently sideways hitting a bump.

wexandproud

after reading about your broken spoke, I would question the quality of the wheel build . If your gears were working ok for the first few spins , it could easily happen that the spokes loosened in the rear wheel and the 'dish' of the wheel would become off centre causing your spokes to pick up the derailleur. Have seen it happen

That sucks, you have my sympathy. So much worse happening on a brand new shiny bike than after a year or so when you are out of the "honeymoon" period.

I hope it works out and ribble step up.

I ripped a derailleur last week. A flattened plastic bottle got flipped up into my chain by the front wheel, snagged the deraileur and ripped it off. Quickest 62 euro I've ever spent.

Happened years ago too with a branch.

godtabh

I had an old wheel set in it this morning as the other wheel that Ribble supplied is being replaced under warranty. The wheel set that was in it today was serviced about two weeks ago by the Bike Rack who I would have the highest confidence in.

I dont know what gear I was in. Big ring in front and probably mid way through the rear one.

Hangers don't flex. They're stiff but brittle.

Well just be thankful that there is a separate derailleur hanger. I have a beautiful metallic sky blue Klein MTB frame sitting in my shed where the hanger was integrated into the frame and is now ruined after a similar mishap.

I had bought a heap of new drive train stuff for the bike and just lashed it all on in a rush with the intention of adjusting everything the following evening. I went to work, shifted down coming into the car park, and the derailleur went into the wheel. The threads were torn out of the frame and the hanger part was bent. It's all integral on the Klein so you can't just replace it, and aluminium alloy doesn't really bend back and forth too well. The worst part was that I knew the thing wasn't set up right and I just went one click too far as I was at lower than walking speed in the car park. Grrarrgh!

Would this help?

Holy sneck! It just might. I'll order it and find out.

Previous suggestions were based around helicoil(?) type stuff being added into a drilled out version of the original hanger, but this would weaken the hanger a lot, especially as it has to be bent back into shape.

I'll report back later...

Have a MTB built up as a single speed and it's a lot of fun to ride if all else fails.

From what the LBS/Ribble are saying its cosmetic and likely caused by poorly adjust limit screws or a bang.

I didnt adjust the screws or remember getting a bang. If it was out of sync I would have expected a warning i.e. the sound of spokes being touched.

Either way I have my wheels back so at least I can ride tomorrow.

Ribble have asked for more photos/info so I will leave it with them.

I highly doubt your wheel chewed the jockey out of the dérailleur ...the bolt holding the jockey is a hell of a lot stronger than your spokes. You'd have lost a lot of spokes before it would have been ripped out....and got it to be ripped out it would need to be well anchored for the duration if the assault.
Do the threads look stripped on the side that said bolt threads into?(indicating it was ripped out...or ar they in good nick indicating it worked loose?)

Does the bike come fully assembled with the gears adjusted? If so id be certain to inform Ribble that if it was caused by poor adjustment then that is down to them and not you.

Bike came assembled. Just add some wheels.

I had exactly the same thing happened to me on an old Peugeot frame with integrated hanger. 105 mech (5700) caught spokes while accelerating from a corner, both jockey wheels detached, cage ripped off completely. Wheel was untouched, except for some scratches on black spokes. Even chain twisted and broke, frame was a write-off - hanger deformed beyond repair.

Don't underestimate the power of spokes.

godtabh, really sorry to hear. I can only imagine the level of your frustration. If the bike was in middle gear, it would indicate that the mech bolt was undone, most likely... I guess you don't have a photo that would show the chain position...

Yes i get what your saying but (IMO) the derailleur would need to be anchored firmly for the spokes to do that sort of damage...your older hanger may not have broken as easliy as the ones today designed to break easily.
Incidentally did it rip the screw bolt heads through the derailleur sides or did it shear the bolts(jockey wheel bolts)

I don't remember, but note that the cage on 105 rear mech is composite, not that hard to rip a bolt from it.
