What's new

My New Weapon

Mike that's shocking! :eek:

Push for warranty on them. There's no way a high-quality wheelset should fail in one descent, especially as it's the back wheel that takes less of the braking load. Plus Easton trumpet their heat resistance.

ps - you should have taken my old advice to heart :D

Actually, I reckon you need some seriously bomb-heavy wheels with no aerodynamic features, which you must buy and install before Hotaka :p
 
This is a common issues with ALL 100% carbon rimmed bikes and one of the reasons why I won't go the full carbon route.

The only wheel sets I know that don't suffer from this are the Shimano Dura Ace and Pro-Lite wheels as they have a ceramic coating over the breaking surface.

I'm not sure if this will be covered by the warranty as it's something a lot of manufactures mention in the manuals and warranty. I really hope that Easton do cover it though.

On another note..... Loving the Mavic's Mike! Stripped the freebody down yesterday and serviced with Acor low friction grease..... Silent, smooth ...deadly!
 
Unfortunately the rear wheel is ruined after the forced slow descent by the organizers on Azami
That must be very frustrating for you. Your wheel is ruined AND you missed out on a zippy downhill. Although I'm sure the organizers had safety concerns, for me being able to zip down as fast as my cojones will allow is the whole point of climbing hills.

Norikura Descent

Very sorry for you Mike...I'm sure it would not have happened if you were allowed to do the descent in a natural way without being forced to slow down behind the organizer's escort vehicle. It happened before at the same race.

I'd go for aluminum rims henceforth if I were you!


Unfortunately the rear wheel is ruined after the forced slow descent by the organizers on Azami:( I'm waiting for a reply from Easton as to what the repair bill is going to be. Basically the heat has caused the carbon to melt and cracks have appeared! Wonderful stuff, after I've only used them once. I'm having such luck with wheels:mad:
 
Tom, that looks more like an impact than an over heat.

From Easton!

"When we were getting ready to launch our first hybrid carbon wheels we gave some to the team [Astana] and they were able to cause it to fail due to heat," said Adam Marriott, Easton's wheel product manager. "So we realised there were some issues, and didn't launch it. It then took another year-and-a-half in development. In the meantime, we developed a test to simulate what the team riders were doing in a matter of weeks, but what mere mortals weren't able to do."

I guess its offical Mike..... you're a cycling Deity!
 
Overheating seemed to have been the cause

Tom, that looks more like an impact than an over heat.

perhaps so - I wasn't there - but the crash impact was apparently triggered by the overheated rim...as Sora-san who saw it happen reported:

1。過度のブレーキングでリムが過熱した。
2。リムの熱でチューブ内の空気が膨張しパンク。
3。接着しただけのカーボンリムのため、勢いでホイール自体が全壊。
4。コントロールを失い落車、後ろを走っていた人も巻き込まれて大事故に。最低でも骨折、救急車出動。

1. Rim got overheated due to excessive braking,
2. Overheated rim caused the tube to overinflate and burst,
3. Since the carbon rim consists of glued-together pieces, the entire wheel got destroyed by the impact (of the tube burst),
4. Rider lost control and crashed. Riders behind him could not evade and got entangled in a major accident. Ambulance came to rescue...broken bones likely.

Fortunately Mike got away without a crash and broken bones...:angel:
 
Mike, I did apply oil to the Mavic freehub according to your recommendations. Using light racing oil I noticed an improvement, but still wasn't satisfied and went for the full freehub maintenance. Now it runs like a champ.
There is a good video here:
http://www.youtube.com/watch?v=FzoBeJ5HaOI&feature=related

Mavic recommends mineral oil, an alternative would be a lube that liquifies upon use. I wouldn't use ceramic grease, as
-it clogs up the paw hinges because it is too heavy
-it does not mix well with light oil, which is best to apply through the lip behind the sprocket without disassembling the whole freehub.

As opposed to what? High friction grease?

Seriously though, I'm tempted to do this as well. Would Finish Line Ceramic Grease be suitable, do you think?

Mike, been using the Finishline products for years but got recomended the ACOR by the LBS...... this stuff makes the normal low friction stuff feel like high friction grease...... and yes the ACOR liquifies on use.
 
One product I am very satisfied with is Verity Oil
http://www.sanwakasei.co.jp/verity/

It comes from motorsport, but since about two years the inventor is marketing two cycling related oils. One for the chain and one for hubs/bb.
He has been out on open Keirin events offering free samples and servicing himself. The 604 chain variety is very light so you have to reapply after a couple of hundred km, but riding is unbelievably smooth - as there was no friction at all.
More and more keirin racers seem to win races with it, what better marketing can there be?

That is the one I use on my fixed gear, for the ole road bike I use Finish Line ceramic grease for durability.

I will report back, once I have tried the hub/bb oil.
 
Thanks guys and I'm glad what happened in that picture Tom posted didn't happen to me. I'm currently in the process of reboxing the back wheel and sending it back for inspection. Will keep you posted as to the outcome. I doubt I have any case though, and am preparing myself for a wheel rebuild at my own cost. Still quite unbelievable after only one ride:( I will definitely ride the truck down next time. An expensive lesson.....
 
Mike,

I feel your pain mate. Hopefully lady luck will smile on you..... you could always send the organisers the bill ;)
 
Terrible news about the wheel but surely it is covered by a warranty!?

Most bike parts are covered for 2 years or 1 year minimum for failure under normal use. Applying the brakes is normal use.

In the past few years I've made successful claims for a failed carbon seat post, a failed carbon frame and failed compact carbon cranks. In each case it has been a laborious affair but in the end I've come out better with newer versions of the models originally purchased.

My advice to you is:

1. Take the wheel to a decent shop here in Japan before you send it anywhere. Get the mechanic to confirm the reason for the wheels failure. Use this information in correspondence with Easton.

2. Don't just contact Easton. Contact the seller who sold you the wheels. They should want to help a valued customer. They should also have experience in making warranty claims.

In my experience with FSA, they wouldn't accept claims from the customer directly. The shop had to make warranty claims on my behalf. If they are a decent shop, they may even give you replacement wheels while the damaged ones are going through the warranty process.

3. Make copies of proof of purchase and take lots of photos (including good close up ones) of the damaged goods.

4. When you ship anything get it fully insured. The bastards at pedalforce tried to claim my frame had been crushed in the post! Thank god I had it insured!

Anyway, hope these ideas help.

Good luck with the claim,

Andy
 
Yeah, best of luck with the wheel. Isn't Easton owned (partly) by Campagnolo? Anyways, they are playing catchup with Mavic in terms of becoming a household name, so hopefully that motivates them to have generous service.

But yours and Sora's story made me think twice about wishing for carbon wheels.

I do remember coming down this winding paths in the woods in Shikoku with maybe 800 meter elevation change on my fixed gear with only the front brake and my legs shot. It was a hot day and I stopped twice to let the alloy rim cool down because it had gotten too hot to touch. Probably would have fouled out with carbon (which I wouldn't put on my fixed gear, but still)
 
Andy, thanks for the advice. Unfortunately I had already sent the wheel by the time I read your post. You'll be glad to know I got insurance, and sent it back to Chain reaction rather than Easton. Hopefully they'll help me here, but who knows! I'll post something as soon as I get the news.
