I have had my 575 Carbon for about 3 months now and i would like to say that it has been amazing, until today. I am not a great XC rider by any stretch of the imagination. But i do have a good sence of balance and a rational fear of everything. Needless to say i have not fallen off of it so far. I also have not attempted to drop anything bigger than your average kerb stone. Today me and 2 buddies took a road trip to Afan for a gentle ride around the whites level trail. About 15 - 20 mins into the ride i was putting some power down to get over some loose rocks . Suddenly the back end felt a little funny and the i could hear my tire rubbing (impressive as i run 1.95" CINDER's). I pulled over straight away and checked that my QR skewers were still tight. They were.  I gave the back wheel a wiggle and there appeared to be movement of the chainstay under the neoprene protector. I peeled it back and to my horror this is what i was greeted with.     I have only ridden approx 100K on it. Has anybody else experienced a problem? Regards Bezzy |

a case of bad luck i think...my asr-sl was the first year that they had carbon chainstays...i've had it 2 years now and no problems at all...i'm no expert, but an aluminium break in the same area may have been more potentially dangerous...speak to the shop where you got the bike, failing that speak to Mark or Howard at Evolution...it may be a warranty replacement, depending on how it happened of course...

Will speak with the shop tomorrow.
I was only climbing up a gentle slope with a few small loose rocks.
So nothing the bike shouldn't be able to take in it's stride.

you should speak to your dealer who should get it replaced via importer who may or may not want to check it first ride my last post in tech questions on the same subject

Bezzy- I've not had any problems with mine yet and hope you get that sorted under warranty.
You SHOULD do - post up as sure me like all the other Yeti owners would want to know.

Got my bike back saturday.  Yeti replaced the rear end within 1 day of receipt with no quibbles at all. Top effort by the chaps at Evolution. Just goes to show that the Yeti warranty works like a dream if you ever need it. Take this as a cautoinary note for all who think about saving a few £££'s importing!!!! |

When I bought my 575, Biketreks advised against a carbon rear end. They said that riding rough Lakeland terrain was likely to cause just these problems. I bought alu.
Are the new frames all carbon rear ends, or is alu still an alternative?
To my uneducated mind carbon fibre frames on mountain bikes is a recipie for disaster.

Fagus, there are hundreds of carbon frames on the market, and there are hundreds of 575's with a carbon back end sold every year, if two have failed, how is that a reason to believe that carbon is a poor material for a mountain bike.
I wouldnt believe a word Biketreks tell you, they happily sell the Full Carbon Scott Genius and quote "the new generation Genius is going to be THE bike to ride!"

I still wouldn't touch a carbon framed mountain bike. Maybe soft southerners riding their 575s on canal towpaths can get away with them, but rattling down the Garburn will throw up any number of rough stones/rocks that are just designed to smash carbon fibre. Works riders are different, they just get given a new frame, but some of us have to pay for our own stuff. I cannot see how anyone would willingly put themselves in a position of possible frame failure. Unless of course you are more interested in posing "Look at my carbon fibre" than getting out and riding. Or perhaps selling them is good business!
Slagging off other retailers certainly isn't good business.

Had mine for 11 months now, been in the Peaks and all over riding it, no problems. It gets ridden 2-4 times per week.
I used to be afraid of carbon, but having had it, I can say I would happily have it again.
The main thing with these 2 breaks is they have not been sudden and have broken safely like Carbon is now designed to do. Carbon frames and parts are designed to act more like steel in to 'fail safe'.
I think these 2 people have been unlucky, but Yeti has sorted them out.
Unsure how it could have happened, but these sorts of things do happen to all bikes, and cars, and other goods, its not if they go wrong thats the problem, its how they sort them out that counts.

Fagus
I cant remember how many times I have ridden down Garburn pass, and my Carbon swingarm miraculously survived.
Plus the demo bike survives countless trips to Stainburn. (which is a fantastic bike and limb destroyer)
I was merely pointing out to you that Biketreks sell full carbon bikes and are now claiming that the Genius will be THE bike for next year. This merely highlights that they believe carbon fibre is a good material for mountain bikes being ridden in the lakes.
I assume that you are from the lakes and are on good terms with the guys at biketreks, which is good all round, but I think you should do a bit of research on carbon fibre (not reading forums) before dismissing it as a material.
I personally am from Leeds, but I am sure there are a lot of guys from the south who ride their bikes on more than towpaths, and would probably be a lot faster up and down rocky tracks than you and I.
And although I am a shopkeeper, I do have to pay for the bikes that I ride.
But the beauty of forums is that we all have different opinions, and I doubt I will convince you of the merits of Carbon, but then I dont want to.

Everything has it's place. I quite happily run carbon bars despite all the horror stories of them breaking. But using a frame material that only needs the slightest contact with rocks to potentially cause problems is a step too far. The weight savings are small compared to the potential inconvenience of a broken frame. Even the guy who was whingeing about his dinged frame could still ride it home. The carbon boys were walking.

Fagus do you realise that Rally Cars use Carbon bash guards, my Yamaha has a carbon bashguard, Carbon is used specifically for its resistance to damage from rock strikes.
The boys on the 575's that were whingeing about their dented frames would have not had a mark on a Carbon bike.
(my opinion of course having lobbed a Carbon Ransom down the rocks at Stainburn to discover a couple of chips in the lacquer- the frame is still ok two years on)

to look at this from another angle I test rode the asr-c not long after I stopped being a roadie and was still getting my dirt feet settled and surprise surprise I dropped the asr-c more than once my fault not the bikes however the bike faired just a bit better than me as it did not have a mark on it whilst I did however there is a lot to be said for if you cannot afford to break it do,nt ride it p.s. there is a guy in my bike club who has had a carbon hardtail for quite a while now uses it several times a week and no marks no breaks

I gave the back wheel a wiggle and there appeared to be movement of the chainstay under the neoprene protector. I peeled it back and to my horror this is what i was greeted with.
