部品：折りたたみブロック用クイックリリースクランプ

The clamp fit my Flex folding block perfectly and the lever locks with a solid click instead of the mushy feel the old one had. Took maybe two minutes to swap on.

Snapped right onto my Speed+ folding block with no wobble at all, and the lever locks tight enough that I don't worry about it popping open mid-ride. Took maybe two minutes to swap the old clamp out.

Wasn't sure if this would fit my Rocket, but the quick-release latch engaged perfectly with the folding block. Took less than a minute to swap, and now folding is smoother than before.
