I'm a newb when it comes to carbon/composite components...so please bear with me.

I just took delivery of these brand new 2008 Easton Monkeybar XC bars. Last night I installed them and torqued them to spec (per my LBS...5-7 nm on the stem and 3-4 nm for the levers). I torqued the stem bolts to 5nm in the proper sequence and the levers to 3nm.

Take a look at these photos. It looks like some sort of crack underneath the top coat. But, upon further inspection it also looks similar to the seam on the top side of the bar. I've never ridden the bike with this bar and this is something I noticed after I wrapped up the install. Not sure if this was always there or if it developed after the install (I didn't closely inspect these bars prior to install).

Seam on the top of the bar:


Area of concern:




This area of concern spans the entire bar. Is this a crack or nothing to worry about?

I'd like to add that I can run my finger nail over it and it doesn't get caught AND I didn't hear any cracking/crunching when I was snugging down the stem...so that makes me think it isn't a crack.

I believe what you are seeing is the actual fabric seams in the bar. Easton used to put a pseudo weave on the outside like many manufacturers do to make it look nice. It was for looks only and provided no structural support. They stopped doing that so you now see what the actual layup looks like. It isn't always pretty but doing away with the cosmetic weave saves a few grams.

You are spot on (exactly what Easton just told me).

A senior brand manager from Easton just took a look at the photos and ensured me it is a normal striation under the clearcoat. He also applauded me for using a torque wrench (I figured that was a given with carbon bars).

Even better...he got back to me within 15-minutes of me sending them an email with the photos. Talk about awesome customer service!
