1983 Diamond Back Ridge Runner II
The Diamond Back Ridge Runner II was the
replacement to the original Diamond Back Ridge
Runner manufactured by Centurion
in Taiwan.
It may look very similar to the original, but the
differences were many.
The Ridge Runner II was manufactured in 1983/84
and was a non lugged Cr-Mo 4130 steel frame.
The geometry of the frame had an extra long rear
triangle which made it very stable on the trail. It
had all the braze on mounts for touring racks,
fenders, and 2 water bottle cages.
It was released in two-toned combination silver with black trim.
The chrome diamond shaped handle bars, which are
unique to Diamond Backs, are similar to the original
Ridge Runner's, except they no longer have an
attached brake cable stay.
The front and rear dropouts are generic.
The most noticeable difference between the Ridge
Runner and the Ridge Runner II is the missing lug
work on the frame. Also, the forks are different
than the original Ridge Runner and they look
identical to what was used on the Specialized
Stumpjumper.
