[Closed] SRAM eagle problem any one experienced it?

Same here, chain dropping out of bottom jockey wheel getting trapped on Eagle X01 and ripped the top jockey wheel off destroying it along with the inner cage. Happened twice now, not happy downgraded to GX, less of my hard earned cash to flush down the toilet which is where these mechs should go

not limited to Eagle, happened to me last year on my road bike running 105 and 10 speed block, and a mate of mine on his hardtail mob, not sure what he was running but definitely not Eagle.

I never sussed out what it was in my case, however I had just done some last minute maintenance on the drive train so assumed it was my fault.

My mates mtb was a carbon hardtail and the rear mech was rotated around the cassette and snapped cleanly through his seat stay. He got the frame repaired at a local carbon frame repairers but he commented that it was by far the most common repair he has to do, so clearly not just a problem with Eagle, alot of people out there suffering this issue.

Wobbliscott - Last one sounds like a split chain jamming in the cage which tears mech/hanger off and through seatstay. Different issue altogether.

My rear Mech is going back to SRAM they just provided new jockey wheels before but it damaged the mech this time, always on a downhill trail as everyone else's, Mine is happening mid range been told to change gear slower so will see what happens when it comes back next week.

I sent mine back for warranty. They've equipped it with new jockey wheels and inner cage.

I've just spent a week in Sierra Nevada with Ciclo Montana and the aftermarket spare I had worked flawlessly. That said, we were riding a lot of slow and technical stuff, so I guess the conditions where the first one blew up didn't arise that much.

must admit, mines hasn't since does this now (about 5 rides in, tried and tried to fast shift in smallest cogs, up and down, down and up), since I put some new pimp alloy jockey wheels on and/or a new cassette

so it appears the problem for me was one of the above, a new chain DIDNT cure it.

Same happened to me on Sunday. 4 week old gx eagle mech. Low down the block pedalling hard and boom. Dead mech and sore plums!
Hoping sram can sell me top jockey and new back plate.as it's ripped the thread clean out the back of the cage.

It's due to the metallic purple cable end.

Your gx couldn't handle the embarrassment of the colour clashes on yer bike and killed itself.

I wouldn't be asking them to sell you anything, id expect a full warrantied mech, its a joke that this is happening, its clearly a design fault somewhere, its the same thing I keep hearing now, pedalling hard over rougher ground in the smaller cogs, once you start chaning gears around it cannot cope at all, so a clear design fault

the only option is to try and stay in the same gear when over rough ground, which is pretty impossible, and pretty shit that you should have to do such a thing

My lbs has spoken to sram tech and basically they didn't seem interested, but due to its age, to send it to them to inspect.
I personally want a new mech out of them, but how long does a sram warranty claim take??
Did you deal with them direct?

Himm this thread (and some others on pinkbike and MTBR) is worrying. I'm off to Ciclo in a couple of weeks with my Eagle x01 equipped thing. Reckon I should purchase & pack a spare mech?

they will say that, its usually srams response to anything, 'oh we know nothing about it' (they said the same to me about 3 pairs of creaking pikes I had some years ago), I believe they do, if its happened to just a few of us on STW forum, imagine how many else its happened to in the world that just haven't reported it....

I woudlnt settle for anything less than a new mech tbh, and Id argue all day long that its a design fault, point them to this thread!

also I haven't actually warrantied mine, mines is 9 months old but only started doing it a month or so ago, ive replaced the jockeys, which touch wood so far has cured it for me, but obviously if your mech is 4 weeks old then it kinda blows the new jockey wheel theory outta the window...

if mine does blow up like yours has, I WILL be taking it back to the shop to warranty, if they don't warranty it, Ill be going back to shimano 11 speed

Typically, I have just fitted GX Eagle Dave 🙂

I got spanked £50 for a set of sram jockey wheels on my xo1 11 speed mech, god knows what they charge for the 12 speed ones, especially as it says 'eagle' on it!!

😀 kev you'll love it, aside of this problem mines was absolutely spot on for the 1st 1000miles! shifting went a bit slow down the cassette, but a new cassette and jockeys has sorted it

I cant fault the feel of shifting etc etc, its really good when it works well

just be very very very careful to change up gears when you are in the smallest cog (shifting up to next one) over rough ground at speed

other than that you'll love it kev 🙂

the official eagle ones (which are shit and have shift life in the bearings!) are around 70 quid! ive got some rather nice pimp alloy ones that feel totally solid for around 50 euros (proper eagle sized ones)

I took a spare but mine survived. That said, we did a week of the slower techier stuff with little of the down the block high speed pedalling that seems to cause the problem.

Gonna see if I can source a back plate and pulleys. Seems they're about €70.

Riding down places like Arthur Skargill & the run into the Lanjaron 70 might do it in.

OMFG how much are the bananna connectors! What the hell have I bought into?

Eagle seems like one of the products that's great in theory, crap in reality. Unless you're a racer/sponsored/pro/obsessive fettler, seems to me like you're better off without it for hassle-free riding in the UK.

Thats a poor excuse for it not working reliably. XTR is aimed directly at those people & it just works.

Arthur Scargill and Lanjaron 70 were both ok, as was the Valeta run and Super enduro, but not really any cranking required on those.

Thanks folks. Was considering Eagle on my next build but this has been enough to put me off.

At my current rate they'll have moved on to 15 speed by the time I reach 1000 miles!

Been out on it today and it's spot on, very happy.

Offt getting the feeling I have dodged a bullet here!

Had this happen to me a couple of times, chain caught between the lower pulley and the cage. The first two times I was lucky to catch it. Not so lucky on the third , completely destroyed the derailleur and 2 two spokes. Good news is Sram warrantied it and the chain. I believe a design change is needed to the cage to keep chain from being able to drop to the sides of the pulley, especially in rough sections when the chain is bouncing like crazy.

yep I think there is too much space on the cage for it to bounce and wedge into the sides, not sure why where the jockeys sit, there needs to be excess space either side? it certainly doesn't need enough excess space for the width of a chain to sit perfectly in and get wedged

glad you got sorted under warranty, that's good to know

im not sure if its a combo of the play (very quick and very excessive side to side) in the jockey wheels themselves, combined with the space on the cage for the chain to fall into, it definitely needs redesigning

ive had some alloy jockeys in the since it kept happening (same eagle size ones), the bearing is still solid with no side to side play 1 month on, ive not had this issue once since, as hard as ive tried to replicate it, so its got me thinking the side to side play that comes from new in the jockeys is too much regardless (they almost need to not have any float which my alloy ones don't and it shifts perfectly), and then over rough ground, the side to side play allows the chain to move so much/ not mesh properly as its changing gear that it comes off, then falls into the dreaded excess spacing either side of the jockey in the cage

I don't think anythings changed on them alex from what ive been told, maybe there is a design change for the future tho 😉

Holding off pulling the trigger on gx eagle for the fatbike.... Gx 11 has been faultless though.

Lower jockeys shouldn't float,only the top (i.e. side to side). That might be the issue thats been designed in, by accident.

There is definitely float in the lower pulley with the new derailleur. I am guessing that this is by design to ease the angle of the chain at the upper and lower end of the cassette. It would also reduce some noise and wear to the pulley, but it could be the root cause with chain jumping off the pulley as well.

My replacement non sram ones are rock solid both upper and lower

I think it may well be the culprit, even from new theres play in the sran lower one, enough to not sync the chain over rough ground side to side and bam into the cage

Ive tried and tried and tried down rocky stuff the other night and shifted gear and not one problem at all on the new non sram ones

Got a link to the after market jockeys then?

I have had 2 rides on my new bike fitted with GX Eagle.
Both rides have ended due to the rear mech spitting out the top jockey wheel.
Its back in the bike shop having mech number 3 fitted in 34 miles.
Both times it happened to me was at the same place on the same trail a week apart.
I thought it may be a bent mech hanger as the chain has been rubbing on my tyre (see pics) but the bike shop had it in the workshop while i was there and they said it was fine.
Be interesting to see what they say when i pick it up later this week.....

Just a quick update my bike has just shattered its 4th Jockey Wheel the bike is 10 weeks old, new chain just fitted on its first free service so that can be ruled out. The bike was also found to have broken fork internals and the dropper jammed on the very last ride. Bike is fantastic but no faith in the Eagle gx rear mech has anyone had problems with the higher spec eagle? Or is it just the Gx?

I have had my gx transmission fitted for a few months. No issues to report apart from it's a little noisy on the 50 and jumps off the 10 sometimes if I back peddle.

Little bit worried having bought into gx eagle....

Did you use the red chain set up tool?
Was the shaped quick link on the right way matching the chain travel?

I had a look at the rear mech and the top jockey wheel doesn't have loads of clearance to the chain and nowhere for it to catch IMHO.... Very little float either.

A bit of an update from me, having had the bike back, the mechanic did actually confirm that the mech hanger was bent.
New hanger, new mech and even though i have only had one ride on it since, it was shifting very well and is still in one piece..
I will probably head back down to the fod this friday and see how it behaves.

I fettle my own bikes but I have never seen a derailleur be so sensitive to the hanger. I have a hanger tool as well but even with the best straightening I could manage the big rings remained a mess when shifting. When I examined the old hanger it was off by maybe a couple of degrees from straight in comparison to the new one but I am sure any other derailleur would have coped. It's also extremely sensitive to the B-limit setup. i'm assuming due to everything just being slightly narrower.

Great when it's working well though! Just hoping I don't go through several hundred derailleur hangers to make it so!

Bike went in to the shop today, the frame had been checked previously for alignment and the hanger there going to re check the frame, hanger and the gear shifter to see if there's a tension problem although it would mean it's intermittent and that would be a mare to find. I've been promised no matter what it's going to be fixed as I have mentioned rejecting the bike.
Can I ask every one the following questions to find a possible link;
1. Make and type of bike
2. Age/miles when failed
3. What type of trail were you riding when part failed
4.are you clipped or flat and shoe size

Thanks inadavance

5. How quick did a replace the fail?

Whyte s150s
3 weeks 1st time but average is 5 rides.
Red route, not that ruff but a few jumps
Flat size 12 five tens
From very next ride to 10 rides

Whyte 909
Failed 1st ride 17 miles in.
Failed 2nd ride 17 miles in.
Survived 3rd ride.
Both times i was riding the top part of Launch Pad @ FOD, is that a blue??
Clipped in, size 10.

There's a new hanger just out for the Eagle read into that what you will, the hanger will space the upper jockey wheel further away from the cassette.

Any more profiles would be much appreciated
