A sophisticated combination of materials significantly helps
to reduce weight of the glider (to 7.3 kg). The BiGolden3 is the
first Gradient tandem glider where we have used Everlast,
a double-coated Porcher material. Everlast was developed
by Gradient in co-operation 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.
