That's a big climb, Hell Cat! My old Pajero used to overheat the gearbox driving up there!

I hope the USADA are satisfied now; they got their man,...

I still to this day believe he is innocent even though he stopped fighting the charges to clear his name

[ratter]

I have mixed feelings about this but believe somebody is out to get him for sure and would not rest until they did

[blueoval]

I think it was a witch hunt. But if there is proof there is proof, you still cant take the time he had on the podium away.

My Latest acquisition

just a little update.

Last weekend, I killed my RD on a local group ride in the country.

To put it short, the rear derailleur, chain, hanger is cactus. Not sure how it happened or why but it lunched itself on the flat after an up gear change doing about 25kph, popped the chain off the cassette and wedged itself between the spokes and bottom gear, locking the back wheel up and tearing the RD off the hanger which ultimately then wrapped itself around the cassette with a twisted chain and ending up in a mess. It all happened within a few seconds and I had to think quick as I couldnt pedal, the bike was pulling up fast and and I was still locked in to the cleats, so pretty much fishtailed it to a stopped and ended up getting my left foot out in time to get my balance. It could have ended worse. Lucky it was on the home stretch of the ride.

The bike is at the bike station now (where I bought it from) and is still under warranty. Hoping to have it back by the weekend pending no frame damage.

I expected better from Shimano Ultegra groupsets.

Will report more later

[Hell Cat]

That would be from wrongly adjusted limit screws or also possibly a sticky free hub

[DBourne]

wow, wtf happened there??

I have all ultegra rear components and no issues at all *touch wood*

[blueoval]

I don't know as I am not a bike mechanic.

Just got off the phone with the bike shop about it. I wasn't on the phone a long time so the conversation was brief due to my frustration. Anyway, in a nut shell, the bike shop will not warranty the damaged components or anything else it damaged due to Shimano themselves claiming it wasn't their component that failed.

I fail to see how me changing gear and the gears not doing what they are designed to do, not in any way showing some form of accountability.

I do not touch gears, I dont even adjust brakes because I value my warranty that highly.

Really disappointed with my bike shop whom I held in high regard, and Shimano under the same banner.

Again, what had happened was, I was accelerating and got to about 25kph, up shifted to the next gear and then heard crunch followed by my legs stopping and the back wheel locked. I did nothing else to cause or inhibit the gearing to change.

[Hell Cat]

How old is the bike? That sort of damage only happens from crashing or in your case the gears not being tuned properly & the chain over shifting ino the spokes.

It's not a shimano warranty, it's more to do with the adjustment of the gears so the bike shop should be covering it.


(I work in bike shops & the past 3 years ran my own bike servicing business)

[ratter]

Wrongly adjusted limit screws would have shown up before this I would think, basically when the biggest gear was selected for the first time.

I had a similar thing happen to me once on my old mountain bike, but it was caused by a chain failure, a link opened up and caught on the rear derailleur, pulling it into the spokes and then grabbing and bending it more.

many people have a habit of lying there bike down or leaning it against a wall etc on the right side, this can bend the rear hanger and put the adjustment out.

[blueoval]

Mate, I am SUPER careful on how I lean my bike. 99% of the time its leaned up against my wall in my lounge via the handle bars and/or saddle.

Anyway, this happened after 30km of riding, you would think that a bent hanger would cause problems well before then.

The bike is 5 months old. Bought back in April of this year.

Regardless, this is what I found online regarding Shimano components.

I destroyed one once by not checking my bike before I got on it and hammered down the driveway.. Only got about 1 meter because the bike was leaning near a basket of washing and a sock was laying on the chain lmao. End result was a snapped in half top of range Shimano derailleur. Be wary of socks..

That's what should have happened to me if the RD was bent like that too. Something tells me its got something to do with the adjustment, or lack of adjustment made to the RD in the first place. But in saying that, this is considered catastrophic failure of a component possibly due to the chain jumping a cog?

[79FordEsky]

Just reading through a few of the last couple pages of posts, some nice bikes I have a bikes, but recently got my RD bike back from rebuild it is a early 1970s alloy frame Australian made, Its nice I have new alloy handle bars, new quick release brakes and new cables, now have a better de-railer and rear 7 speed gog all light weight just need to get another set of cranks light weight and new toe in pedals(My ones snapped (plastic) going fast hit a litte hole then bang). Can anyone tell me where i can get a set of toe in pedals that are light weight.

Yeap a slightly warped hanger will cause dramas instantly. Sorry to hear about your misfortunes mate, especially after you've spent decent coin on a good rig... I would certainly be taking it further.

Did you have the bike serviced recently?

No it was going to go in for one this week though. In heinz sight it should have been last week.

Just an update. Copy&pasted from forum.

Ok. Just saw ####. He couldnt give me a clear answer and put it down to something getting caught in the chain pink and forcing the chain off the RD and causing the havoc. I didnt get angry. I wasnt pointing fingers but i did state i was very disappointed that something pike this happens on a 5 month old bike with no explanation.He said he called both shimano and focus and both of them were interested in owning up. Stated that its too hard tp pin point the actual cause. Had it have been a link broken in the chain then something could be done. But based on what i was fed, it was some mystical fairy that came up and farted on the chain which caused it.That said. Still disappointed with the whole scenario but the bike is ready and looks good as new. Also i picked up my old damaged parts and took some close ups which ill post up later.What will i do now? Well i gotta think about it. Speak to velosure tomorrow. See if they can cover the damage and then issue a claim.Should i fight it? I could but in saying that, how much time, effort and money do i need to spend to prove a point? In saying that, noel showed me 2 other bikes with similar issues and damage both having to pay put of their own pockets. The chance of me winning could take months to prove and i make enemies in the mean time. Not the way i handle situations.Will i go back? Well that depends on the nature of what reason i need to go back. I could sit here and ***** and moan about how hard done by i am and life isnt fair, but again that is not the way i do things or view life. I think i need to put this down to experience and move on.

[Captain Stubing]

That's bad news Shav - you would think that the drive components on the bike are built to take more force than our legs can throw at them.

The RD would have to have gone WAY out of line to twist up like that under load. I'd be thinking it was component failure - you'll have to post up some close ups of the damaged parts.

Good luck with it...

[blueoval]

Will do mate.

Have a read of my blog for some more in depth discussion about it if you have the time. The stuff about the damage starts from page 2 on.

[blueoval]

Picking up my bike today. Looking forward to getting it back and getting on with riding.

I would just like to say that even though in my above post it looks as if im blaming the lbs for not covering the bike under warranty, it was explained to me that the cause and fault of the damage was too hard to pin point to any one person, therefore it falls back on me to pay for the damage and move on.

I want to state that i while i was disappointed with the outcome, i cannot point my finger at any one person and that i will be taking this experience on the chin should this type of incident occurs again.

Let this be a warning to all to get your chain checked and your f&r derailleur serviced and checked regularly. Do not assume your warranty covers all.

Looking forward to doing some miles this weekend.

[TZENU]

How's the bike going now Shav ???

[blueoval]

Bike is back together now mate. Looks the goods. New RD, chain and wheel. Wheel cost the most.

Anyway, a little story yesterday. I woke up Sunday morning ready to attend a group ride up willunga hill. Pumped up my tires to 120psi. Thinking that should be ok for uphills. Sat down for breakfast and then heard this loud bang like a gunshot. Walked over to my bike spotted the rear tire flat minutes before i was to be picked up by andrew. Andrew (my mate) helped me rush and change the tube with my only spare. I get to mclaren vale everyone is already there and waiting, we set off and about 2km in and i hear this scuffing, i immediately stop only to pull up and another bang goes off. This time its worse, side wall of conti gatorskins rips from its beading. Making riding any further non existant. Pretty much walked the 2 km back and rang another mate for a lift home.

New RD



picture of the split in side wall beading.



Got changed, came back down to oxygen cycles in Mclaren Vale and ended up buying 2 new specialized 'all season' armadillo elite tires and 3 vittoria tubes. Hoping these will end my pain.

Shot of new tires


Took the bike for a quick spin around my block this morning as it got too dark last night to test the bike out. Took me over an hour to change both tires and tubes over btw. Finding that the bike feels slightly quicker with the new rubber. Could be placebo. Anyway I hope this is the last of my bad luck and more time actually in the saddle enjoying my bike rather than forking out cash hand over fist fixing it.

[HLC]

Shav, we're you 'cross-chaining' when your RD blew up?? Ie, big chainring / big sprocket? Looks like the chain has over shifted into the spokes, then because the chain has seized, it'll bring the RD up around and bend the hanger until something seizes..

A chain pin may have started coming loose as well and as soon as it came out far enough to catch on the RD, the result would be the same.

To me it looks like cross-chaining though. An expensive lesson to learn.


Gators are crap too. I only use them on my fixed gear because they last a while. But it's with great resentment, I'd use something else if I could find something that lasted half as long due to the ridiculous amount of skidding I do.

[blueoval]

i just hope it doesnt happen again regardless of the cause.

any way to avoid cross chaining?

[ratter]

I used to cross chain a lot a while back, never had any issues with gear adjustment because of it though, my understanding of it is it will just wear the chain and gears a little quicker due to the side load on the chain and teeth

Yep wrongly adjusted limit screw,when you clicked down the gear.

the wheels dont have a chain guard so it very important its adusted right.

[blueoval]

thanks guys. I'll be taking the bike back for an adjustment this week since the RD and chain are new. I'll let the guys know I want it properly adjusted to avoid this being a problem in future. I can live with higher wear if it means Im safe in the saddle.
