===== Disc Brakes =====

Shimano introduced mass produced, cheap, disc brakes in [[https://www.disraeligears.co.uk/site/shimano_bicycle_parts_-_72_page_17.html|1972]] with the Shimano B 700, followed a year later, in  [[https://www.disraeligears.co.uk/site/shimano_bicycle_parts_-_73_page_20.html|1973]], with the hydraulic B900 - and then many other manufacturers jumped on board.  Unfortunately, they were usually placed with low end, department store bikes, and hence never rose above obscurity and respectability.
\\

[[mcr:start|Mountain Cross Racing]] were far ahead of the curve in using the best technology for their downhill machines.
The example below was made by [[vva:start|Victor Vincente of America]] with Brian Skinner in 1983.  Later MCRs lost weight, became refined and successful at winning downhill races.  Despite their success on the race course, few Descenders were made.
\\

Despite MCR's limited early success, it would be another six years before [[http://dansbikestuff.blogspot.com/2013/02/mountain-cycle-san-andreas-and-me.html|Mountain Cycle]] made the first mountain bike specific disc brakes in 1989.  Other mountain disc brake makers soon followed:

  * **1991** : [[https://www.oldschoolracing.ch/archiv/hope/|Hope]]
  * **1993** : [[https://www.rideformula.com/page/our-heritage/|Formula]] - fully hydraulic
  * **1995** : [[https://web.archive.org/web/20101126141111/http://www.amp-research.com/company/history/amp-research-mountain-bikes/|Amp Research]]

Disc brake overkill for a mountain bike.  Appearances were deceptive, as they are actually a tandem [[https://santanatandem.com/brake-tech/|drag brake]] - but they look like they work!((Phil Wood disc brakes were discontinued soon afterwards, due to brake fade and mechanical failures.))

In 1989, Mountain Cycle made perhaps the first disc brakes specific to mountain biking: the Pro-Stop cable actuated hydraulic disc brakes mated to their Suspenders inverted fork.
