Noticed a slight stress mark on my carbon handlebars, took them off the stem and have noticed the clamp area has indented from the stem. The indentation I assume may be fairly normal, but I’m concerned about the slight stress mark that you can see on the first photo on the right, where the outer layer looks to have pinched a bit.
The bars are 3T Ergonova Ltd. The stem is an Extralite Ultrastem. Tightened to the recommended torque of 3Nm and used carbon paste.
Am I being paranoid? I sent an email to 3T to advise.
