The first pair of the third prototype of my “off-road” skate roller skis is ready for testing after bindings are mounted. Here are the specifications:
Shaft: Solid birch, 44 x 25 x 580 mm (width x height x length), 360 g.
Forks: Aluminum alloy, 3 mm thick, 250 g/pair.
Wheels: Pneumatic, 47-93 (7 x 1 3/4) with plastic rims and Cheng Shin tires inflated to the maximum 36 PSI, 1 020 g/pair.
Wheelbase: 770 mm
Ground clearance: 30 mm
Total weight: 1 630 g (3 260 g/pair)
The wheels are actually 41 mm wide and not the nominal 47 mm.
This pair of roller skis are made for ski boot sizes 40-43 and for weights 75-85 kg. I am very pleased with how they look and feel. Let’s see how they perform when used.
