All #rgb-frames have one thing in common: They now have a Unicrown-frame and not a square-crown anymore. This keeps damage from your shins when touching the frame in rough terrain or during tricks for example. They are being made of 6061 T6 aircraft grade aluminum alloy.
To achieve a low weight at the same time, Qu-ax mades the seat-tube a lot larger. Sounds weird to reduce weight? Well, this allows to reduce the wall-thickness quite a lot! The tube is 38 mm wide at the low end ? and 34,9 mm at the seatclamp-shell. This results in incredibly low weights
The 20" frame weighs only 422g. excl. bearing-sheels (78g) and screws (22g). Qu-ax sheds weight at that end, too ? by putting the thread into the frame-bearing-shell. This is easier in handling ? and saves the weight of those four nuts and washers.
The #rgb-bearing shells are, as already appeared on the latest QX [debut] series frames more more filigran and slim. leaving more space towards the wheel and with a guide for the bearing within the shell.
The 20" is made for tires up to 2,6". The ovalized frame-blades keep the outer width as low as possible away from the legs.
