There are few alternatives to Brompton clamps but I didn't want to go for fancy design mods as I am considering them a key part for bike safety.
Decided to go with SpedClamp, v3 now. It was previously suggested by @berlinonaut and I find products of Eerder Metaal well thought out and engineered.
It has a spring and the clamp itself has one edge longer than the other which allows is to stay aligned when latch is released.
Bolt at the end of the screw allows to set the limit how far you want it to be unscrewed. So you need to think, just unscrew it till it stops and latch is opened.
Screw length is a bit of a close call as it’s barely not touching edge of the tool set. Getting shorter screw if necessary is not an issue though as these are standard ones as far as I know.
Design looks good too.
Happy so far. Hope spare clamps will be available for long time.
