Cracked Easton Bars

My Monkey Lite carbon bars cracked. (Apparently, this isn't too uncommon.) What are my chances of warrantee-ing them? Anyone have experience with this?

Thanks!

Really? I've been running Monkeylites for 3 seasons now on several bikes, without any problems.

I don't know - why don't you tell us how you broke it? What torque value did you tighten your stem bolts to?

No idea about the torque value. I'm no mechanic. I let the guys at the bike shop handle that.

I've had the bike for a year and a half (Santa Cruz Blur), and due to a back injury and my new commute to work, I don't even ride that much, let alone do anything "hard."

I went to a dirt jumping clinic, and the instructor swapped out my carbon bars for aluminum ones for the day, and as he pulled the Monkey Lites off, he pointed to the crack and told me not to ride them again. You could actually *feel* the crack with you ran your finger over it. He told me all bars eventually wear out, but carbon ones wear out faster (especially if you're dirt jumping, which I don't do, but which he does professionally) so I'm heading to the bike shop today for a set of aluminum replacements. I don't really care about weight, but when I held both bars, the weight difference was pretty slight.

So as far as I know, there wasn't a time I hit, and then cracked the bars. It seems like it's more of a wear issue. However, y'all would laugh pretty hard about that considering how little I actually ride.

I'm not too hung up about (shaking fist in air) "making Easton pay!" -- just wondering about the whole warantee process and if it's worth going through the motions.

Thanks!

Is the crack along a seam? If so they should warrant the bar, they did mine.

Also, is it close to the stem? Most shops don't use torque wrenches so there is a good chance they overtightened the bolts or did not tighten the bolts equally.

As far as replacing a carbon bar I typically try to replace mine every 2 - 3 years. I do keep my old bar though just in case I brake one on my bike so I will have a temporary replacement.

If you bought it from an LBS, bring it back, and have them handle the warranty. Worth going through the motions becauase the motions are

1. Going down tho the LBS
2. Handing them the bar
3. telling them to have easton warranty it and you want a new aluminum one

They should be able to tell you whether it is going to work or not.


I am with shane45. I have monkeylites and ec70, and no problems yet. No DJing either

It's a known issue and a manufacturing defect. Easton replaced mine, I sold them, bought Maxm bars, and haven't looked back.

The number one cause of cracked carbon bars (Easton or other) is overtight stem bolts. If you plan on using a carbon bar, buy a torque wrench and use it. Don't trust your LBS to do it. It's not hard, and you know it's done right.

Easton also recommends 2-bolt stem caps to evenly distribute the load on the bar. Many people who run Monkeylites with a 4-bolt cap often have problems.

On that note, I have known Easton to be pretty good sports about replacing bars that clearly were damaged by some knucklehead and his over-enthusiastic allen key.

That is the crack on the seam I was refering to in an above post. I had it happen to me on a 2001 Easton Monkey lite riser bar. They warranteed it no questions asked. However the shop that handled it for me took forever, when I called them about it they told me they hadn't receieved it. Come to find out the owner of the shop had put it up for sale not knowing it was mine.

That's debatable when it comes to some Easton bars. The cracks shown in my picture above are at the seam and a known problem, even when the stems are torque to the proper spec (which they were).

I noticed the cracks on the top bar while on a road trip and bought a replacement bar. Two days of riding later, the replacement bar had cracks along the same seam...

Wow, that's crazy. But that's not where mine cracked. They cracked perpendicular to the seam, right where the bars begin to rise.

Please direct me to where that is confirmed and/or documented by Easton. As I said, Easton replaces a lot of non-warranty problems.

Of course the seam will be the weakest point of a bar. That does not mean it is a "manufacturing defect".

What torque specs are recommended for these bars, as I plan to buy some in the near future. Thanks

70 inch/pounds (each bolt), with a 2-bolt stem cap.

Easton has replaced a great many of the Monkeylites with this problem. See MTBR for more people that have had the same issue with the bars. It's a knwon issue.

If the seam cracks and the stem was torqued to spec why do you assume it's anything but a manufacturing defect?

Take my specific case:

Two bars with the same problem, both bars torqued to spec, one bar with only two days of riding.

If it's not a manufacturing defect, how would you describe it?

I understand that you like to blame these defects on "knuckleheads" for some reason but you need to wake up and smell the coffee:

Sometimes the manufacturers screw up, even if you haven't experienced the same problem with the same part (and if your good bar is three years old it was made before these problems started cropping up).

MTBR means nothing to me. Half of those people are the knuckleheads I refer to.

Proper torque is not the answer for everything. What stem are you using? Did you confirm there are no high areas or "hot" spots inside the stem diameter, and that the clamping bolts were tightened evenly allowing a uniform gap between the cap and the stem? What torque spec did you use? Did you use a torque wrench? Do you know that your LBS did?

So many people think they can use any stem and turn 2 (or worse - 4) stem bolts until snug on a carbon bar and they're off to the races. Any uneven pressure point will weaken carbon bars.

Again, please show me where Easton has confirmed this is a manufacturing defect.

Ah, I see your game now.

It must have been user error because it hasn't happened to you, eh? LOL.

FWIW, yes I used a torque wrench and torqued both bars to the correct torque setting. BTW, I did this over a year before you figured out what the proper torque spec was fro your Easton bar...interesting.

I'm sure for marketing reasons any manufacturer wouldn't put out a bulletin about their flagship product having manufacturing defects. The fact remains however that they have replaced very many of the bars that exhibit the exact same defect.

Why can't you answer my simple questions? Here they are again:

"If the seam cracks and the stem was torqued to spec why do you assume it's anything but a manufacturing defect?"

"Two bars with the same problem, both bars torqued to spec, one bar with only two days of riding.

If it's not a manufacturing defect, how would you describe it?"

I'm just tired of people throwing around words like "manufacturing defect" as though it were gospel, when in fact it was simply your own bad experiece with a product.

You may have had two bad bars, I'm not arguing that. Things made by people are not perfect. But that is a far cry from a manufacturing defect, as I know easily three dozen people (none sponsored or endorsed by Easton in any way - myself included) that have had ZERO problems with their bars. You do the math.

You're dodging the questions again.

"If the seam cracks and the stem was torqued to spec why do you assume it's anything but a manufacturing defect?"

"Two bars with the same problem, both bars torqued to spec, one bar with only two days of riding.

What a specious line of reasoning(and I use that term very loosely).

Again, just because you, and/or your alleged three dozen acquaintances, haven't had a problem with Easton bars doesn't mean that they haven't had manufacturing problems, as evidenced by my experience, as well as the same experience reported by others.

Have you ever heard the term "production run"?

"Do the math" indeed...

Yes. And if it is indeed a bad production run, do you really think Easton wouldn't step up and recall the affected pieces - or at least admit that they had a "manufacturing defect"? Gimme a break. Easton is a class act who replaces more than its share of parts broken by boneheads, so do you really think they would not admit there was an IN HOUSE problem if there was one???

I'm done. Don't use Easton if think there's an issue with them.

Thanks for your permission to use better products. I made that decision a long time ago. No more defective bars!

p.s. Why are you afraid to answer my questions?

"If the seam cracks and the stem was torqued to spec why do you assume it's anything but a manufacturing defect?"

"Two bars with the same problem, both bars torqued to spec, one bar with only two days of riding.

p.p.s. By definition those are manufacturing defects...

All of which Easton says to look for and to correct as needed

Unfortunately this is true and WAY too common

I can't do it. It sounds to me like something was done wrong on the LBS/ end-user level, which doesn't mean a replacement. I'm fairly sure Easton will cover it as they're good like that, but I don't feel the fault is on them.
I will agree with justsomeguy on one thing though. MAXM bars are the shizznit
