7000 series aerospace aluminum,
heat treated using ShapeLoc
technology, is at the heart of
the new 7 Series’ ultralightweight
frame that has thinner,
lighter-weight tubing along with
increased strength. The 7R allows
quick back-angle adjustments
throughout the day, while the
7RS has a fully rigid backrest
and axle plate to further reduce
overall weight. The new Freestyle
Backrest System provides 360° of
upper-body motion.
