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.

Weird Toe-Hole Not Pictured for Product
These socks arrived with a super weird toe-hole that is certainly not pictured on the product photo. If you're over 8, your big toe ain't fitting in that hole. Unless... it finds its way partially into the hole while sleeping and you awake in the middle of the night from startling big toe-pain. Alas, all is not lost! It is super easy to *carefully* cut the toe-hole seam. The result: The pair of toe free socks you thought you purchased in the first place.

Waste of money...
The concept is interesting, however this particular product is a fail. There is not enough elastic/support and the seam by your toes moves quite a bit when you walk allowing the material to swallow your toes and can bunch up under the pad of your foot. Very uncomfortable and annoying. Don't waste your money, these socks belong in the trash!

This sock has a seem between 2 toes -very uncomfortable.
These are exactly the socks I needed to wear after breaking my foot, but there is a big, thick seam sewn in, between my big toe and the next toe. Extremely uncomfortable. I had to use a seam ripper to remove the threads on these socks, so I could wear them. We were leaving on a 4-week trip the next morning, I had no time to return them.
