Polygon 590 SQ brake caliper, hailing from Taiwan and in production during the 1980s (yet still new & unused after all this time!). Made from aluminium and weighing in at 172 grams - pretty lightweight for a brake caliper at that time. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike too.
If you're taking part in L'Eroica or a similar vintage event, these are fully compliant - so rest assured, the pre-1987 police won't lock you up for having the wrong brake!

▼HELP SECTION
-
Position - this determines whether the brake is designed to be used on the front or rear wheel of the bike.
Caliper Type - side pull calipers (single or dual pivot) require nothing more than a brake hole to fix them to as the cable feeds straight into one of the arms, whereas centre pull calipers require a brazed-on or fitted cable hanger to allow the cable to be pulled from the centre.
Brake Drop - measured from the centre of the brake mounting hole to the centre of the wheel rim, measured in a straight line. Your measurement must be within the range of the caliper's given brake drop.
Brake Fixing - this refers to the way the brake is secured to the bike. For recessed allen key fixings the hole to the rear of the the fork crown/brake bridge should measure around 8mm, allowing the allen key head to be inserted and fixed to the brake bolt. External hex nut fixings require a hole of around 6mm, the hex nut is fixed to the protruding part of the brake bolt.
