===== GT Bicycles =====

GT was founded in 1979 by Gary Turner((Gary had previously been making his own custom "Gary Turner" BMX bikes from his Santa Ana garage since 1972.)) and Richard Long in Annaheim, CA, as a maker of BMX bikes.  In 1984 they entered the more lucrative mountain bike market with their Timberline MTB and GT soon began making more MTBs than BMX bikes.
\\

GT's standout design element has been their Triple Triangle™((The Triple Triangle™ was trademarked in 1988: [[https://uspto.report/TM/73752964|uspto]])) frames, where the seat stays attach to the top tube forward of the seat tube.  Introduced by GT in 1987, GT wasn't the first or only maker whose seat stays miss the top.  Other MTB makers include [[3rensho:start#s1987|3Rensho]] and perhaps the [[mantis:start|Mantis]] X-frames.  The frame style is known as //Hellenic// as is occasionally found on older road bikes.
\\

GT sold itself to Schwinn in 1997 and today the [[https://www.gtbicycles.com/usa_en/|GT]] brand is alive and well and owned by [[https://www.dorelsports.com/our-brands|Dorel Sports]].  Gary Turner retired from GT in 1999, a few years after business partner Richard Long died in a motorcycle accident.  After 20 years of retirement, Gary Turner has returned to making "Gary Turner" BMX bicycles with his son Craig.  See: [[https://gt1972.com/|GT1972]].

<div column 50% #s1987>

===== 1987 Avalanche =====
The triple triangle makes its debut, along with a non-bmx stem and awkward rear brake cable routing which is both internal and rubbing against the seat tube.  Later models used cable guides around the seat tube (or added a cable stop on the seat tube.)  Straightforward rear cantilevers have not been seen on a GT since 1984.  See the 1993 RTS-1 brake detail below.
