to make handlebars for trials bikes. The name is a combination - REN from Renshaw and the THAL from Rosenthal.
In 1975 Renthal sprockets entered the
motocross market with full time production in
Manchester, Northern England,
the very same place where the company resides today. The
company had steady growth through the 70's and 80's
and finally broke into the US market in the early 90s.
Renthal currently employs over 60 production staff
and Renthal sprockets are sold in 42 countries
worldwide.
In October 2000, Renthal's factory was destroyed by a
massive fire. What replaced the original factory was a
completely new,
state of the art manufacturing and design facility.
Renthal's 41,000 sq. ft. factory now uses the most state
of the art equipment
available for manufacturing, quality control, R&D, and
storage. This includes five Yamazaki two and three axis
CNC turning centers,
seven Kitamura machining centers, one Kardex Shuttle
500NT automated vertical storage system, and a number of
other custom specification machines. These custom spec
machines include bar bending machines, a fatigue tester
and drop test rig
created to fatigue aluminum handlebars.
In 2004, Renthal sprockets added to its list of
records, becoming the first aluminium handlebar to be
fitted as OE
on a Japanese off-road motorcycle, possibly one of the
highest accolades of quality a company in this industry
could receive.
