Gradient bigoldern3 - Technical Data

Gradient s.r.o., Plzenska 221/130, 150 00 Praha 5, tel+fax +420257216319, www.gradient.cx, gradient@gradient.cx.
A sophiscated combinaon of materials signicantly helps
to reduce weight of the glider (to 7.3 kg). The BiGolden3 is the
rst Gradient tandem glider where we have used Everlast,
a double-coated Porcher material. Everlast was developed
by Gradient in co-operaon with Porcher Sport, and this
exclusive material provides gliders with long-term stability
and durability.
The BiGolden3 is supplied with a well-tried four-riser speed
system with split A-risers and trimmers with a working
range of 8cm.
The total length of the risers is only 35cm.
