Chain-L Posted November 30, 2016 Posted November 30, 2016 I installed the bar very carefully using carbon paste and a torque wrench making sure to adhere to the 6nm stem torque and 3 nm brake lever torque. When I installed the left brake lever i heard a click and upon inspection saw a hairline crack where the mount was in contact with the handlebar. I then removed the bar to inspect the clamping area and there were 4 indentations from the clamp (installed at 5,5nm which is 0,5nm lower than the stem manufacturers max torque of 6nm). Bar instruction states to use stem torque specifications. I have installed many handlebars and have never seen a bar crack at 3nm torque. I am quite sure that it is just the clear coat but don't want to take a chance. Any carbon specialist out there to tell me whether this bar is safe to use? Where can it be tested/scanned for carbon cracks? CRC already replied to me and said that they have had many warranty claims rejected and they will not claim from Easton. I find this surprising seeing that I followed the instructions to a T...... what recourse do I have? Thanks!

PeterF Posted November 30, 2016 Posted November 30, 2016 The 1st pic looks like more than just a clear coat crack.
V12man Posted November 30, 2016 Posted November 30, 2016 Cut that up and bin it - asap Edit - you might want to check with the importer on whether that bar is genuine or not - Easton bars don't crack that easily - but there are plenty of fakes out there - see carbonboy's ritchey bars that broke.... he has a thread somewhere here...
Suidwes Boytjie Posted November 30, 2016 Posted November 30, 2016 Is it a new bar? If so, wouldn't that justify a claim? I'm not a carbon expert, but i'm with RockaRolla, wouldn't trust it.

Where can it be tested/scanned for carbon cracks? Thanks!Are you using a carbon or alloy stem? Alloy stem/carbon stem - carbon bar ...my rule is to torque to 4nm when it says 6nm. I also torque 1.5 - 2 instead of 3 nm when fixing levers etc to bar. I have had the "crack/creek" before. I would not use/sell that bar. Get another on. Your safety is worth more than the money spent on a bar. If you find someone who can scan it let us know. I am sitting with a ZIPP bar....a ladder fell on the bar and make so marks and I do not trust it now. Rather safe than sorry.

On the wrenches it pays to buy a good one. I am a fan of Gedore and Norbar. Gedore agents will have a test rig.
Weimaraner1 Posted November 30, 2016 Posted November 30, 2016 That's not good, I've also got an Eastons bar. So does my wife....but never had issues, touch wood.

Products differ. Strange on an Easton bar although. We have an Easton MonkeyLite on on of our bikes for 4 years now and no issues. I wonder how many carbon bars / bikes with carbon bars are sold with issues....
