At the start of yesterday's ride, Hubby started noticing creaking, crackling, popping sounds coming from the area of the headset. He stopped to tighten the bolts a little but it did not fix the problem. The headset includes a Dimension stem on top of CF spacers. The handlebars are FSA K-Force CF shallow drop.
We called the shop and will take it in tomorrow when the mechanic returns from vacation. The shop said that sounds made by CF frames can transfer from other areas so it's hard to say exactly where it might be coming from.
Has anyone else noticed this on a CF frame (or any CF parts)? It's unsettling (sickening, really) to hear noises like this on these brand-new bikes.
