Dia Compe is the brand name of Japanese component maker KK Yoshigai. The firm was stated in Osaka, Japan, in 1930. The first product off its production line was a brakeset. Though Dia Compe has long since branched out into headsets, suspension forks and stems, brakes and brake parts are what most people rightfully think of when they see the Dia Compe name.

It was Dia Compe who invented the famous "Safety Lever" extension levers that allow a rider to put his hands on the tops of a set of drop handlebars and still stop his bike.

Swiss brake maker Weinmann was was so taken with the invention that the two firms entered a design-sharing agreement. Weinmann could make the safety levers and Dia Compe could make its own version of the highly-regard Weinmann brakes. That is why those highly polished Dia Compe brakes of the bike boom look just like Weinmanns.

Dia Compe New Gran Compe NGC400 brake caliper set. New, $125.00/set

• These calipers are new, they were taken off a new bike.
• These calipers were produced from the mid-1980s to the late-1980s
• Reach: 40mm - 50mm
• Unlike most sets of NGC400 calipers, the quick release is incremental, as on a Campagnolo Nuovo Record side-pull caliper. You can open it just enough to get the clearance you need. The cables are clamped (a far superior method, that forestalls broken and frayed wires), rather than being run through a bolt with a hole in it.
• Upon request, for an extra charge, we can fit these calipers with incassio (allen-key) center-bolt hardware.

Beautifully finished.

Crossbow Straddle Cable Hangers. Used, $30 pair

The website Velobase.com explains: Crossbow brakes were manufactured by KK Yoshigai, aka Dia-Compe. They are a deliberate copy of the MAFAC "Driver" model of cantilever brake, and debuted in 1968. There appear to be versions of the calipers with a red plastic washer installed and versions without it.

Here's the set

And here they are flipped over.
