H&H chain pusher for Brompton folding bike

This is a really small component on a brompton (2-/6-speed only) that most will not notice, but a great upgrade for the weight weenies, or for those who just want the best parts for their brompton folding bicycles!
lightweight at only 5g (versus 14g of the stock version)
allows an additional 1mm of lateral movement for easier gear tuning
POM rollers will avoid scratching surface of metallic pulley wheels (if installed)
material: aluminium alloy, with titanium screws
made in Taiwan by H&H chain pusher for brompton
