Although there are variations in the patterns applied, structures can be classified into “fine”, “medium-fine”, “medium-coarse” and “coarse” structures. The most frequently used structures in World Cup are “fine” and “medium-fine”. For classic races more coarse structures are used as well. The difference between classic and skating is related to more varying conditions in a skating coarse than in a classic track. Also the factor of “feeling” that has to do with the resistance when “pushing” the ski forward is significant in skating, but less in classic. The “free feeling” can be lost, especially when skating uphill, when the structure is too coarse.
Swix Super Riller Structure Tool T401
When using the Swix Super Riller in combination with stone grinding, it is generally after scraping and brushing. In cold temperatures the fine brass blades are used. From -1°C / 0°C (30 F/32°F) and warmer, the medium and coarse brass blades are used. The Swix Super Riller T401 does not deform the base, but presses the structure in. The 1mm and 2 mm rilling blades are constantly used by top racers and technicians on the World Cup. It can give an increase in speed of as much as 1 km/h. The Swix T401 comes standard with the Medium (0.75 mm) blade. Optional blades include: X Fine 0.25 mm, Fine 0.5mm, Medium 0.75 mm, Coarse 1.0 mm, X Coarse 2.0 mm and XX Coarse 3.0 mm.
Swix World Cup Imprint Tool Set T405
The Swix World Cup Imprint Tool T405 is a hand crafted, high quality tool. It comes with imprint rollers manufactured in a very high quality advanced production process. The T405 creates a unique structure in a different way than other imprint tools. The most accurate yet shallow structure is applied in a rolling movement. The steel rollers have a cross-hatch (fishbone) structure for the optimal result. The World Cup Imprint Tool T405 comes as a set with three structure rollers (0.3 mm, 0.5 mm and 1 mm). Due to high production cost, the T405 has been mostly used at top racing levels, but Swix expects its advantages to be recognized by club teams, colleges, specialty tune-up shops, and dedicated World Loppet skiers. The Swix T405 includes the following rollers:
FINE 0.3 mm:
MEDIUM 0.5 mm:
COARSE 1.0 mm:
Practical guidelines when setting structure with hand held tools:
Never clean your structuring blades (or steels) with a metal brush. Use a soft toothbrush.
