The T Line has different handlebar fold clip than the regular Brompton. It uses two little ball bearings with springs to grip a metal plate. Mine is getting stuck in the closed position so that it can be hard to unfold the bars. Either the balls are seizing up or there is too much force.
There’s a screw on each side, one behind each balls. I’ve circled one in my pic. They look like they probably adjust the force on the spring. I can try loosening them a tiny bit but I wanted to check here first to see if anyone knows that this is what they’re for! Thanks in advance.
(I can’t see this mentioned in the owner’s manual)
