    Did I crush my new Salso Pro Moto carbon bar?

    Got a new Salsa Pro Moto carbon bar. Installed it with my regular Bontrager Race Lite 4 bolt stem. The stem says 8nm so I followed those directions with my torque wrench. Ended up getting a slight "noise" out of the bar and the pictures below show the result.

    I guess 8nm was too much? Or is this just the clear coat/paint/etc cracking and the actual carbon is fine? Is this "normal" for a carbon bar?

    I retried it at a different angle just to see what happens with 5nm and at 5 I got an ever so slight indention as well, but no noise. Also for comparison, I put the brakes and shifters on at 5nm and go no indentions or marks on the bar at all.

    As far as torque wrench "calibration", I tested it against my 5nm "torquey" device thing, and it's right dead on at 5nm so I'm assuming it's also correct at 8.

    Here are the pics. I left them huge so you could see the indention.

    Because of previous bashing of vendors I've seen on MTBR, I want to be clear that I'm not saying at ALL that this is a defect in the bar, just asking if *I* broke it or not

    Yes it looks like you did crush them, your not the first to do so, I got the ends of my FSA bars with barends I cut them down and put them on my wifes bike. but there is no saving yours and on the bright side you checked it out before you got hurt,bars are cheep compaired to teeth.

    8nm sounds quite high. I believe most stems only require 4-5nm.

    The one I have clearly states 8nm, but I will tighten my next Salso Pro Moto Carbon to 5nm

    What RL stem says 8nm? It must be an old one.

    8nm is 70 inch pounds. I run only thomson stems with carbon bars and they requre only 35 inch pounds.
