Hey there,
I bought my T2 Road Warrior chair a year ago and some months ago it started squeaking whenever I pushed my back to the chair and it tilted. At first it wasn't that bad but now it's VERY noisy. I can't use the chair comfortably anymore.
When I was taking a look at the chair I noticed something. In the following photos you can see a gap between the main chair support and the string support. I guess that may be the problem.
Thanks for your help!
