LD2040 Two-sided long diamond file, one side grit 200 and the other side grit 400.

Diamond grit 200 allows grinding to remove scratches under the edges. It is also suitable for pre-grinding before the

possible use of the bevel file RACE LTR as well as refining the work of the LD120.

Diamond grit 400 allows polishing to eliminate small scratches under the edges. It is necessary to refine the work of the grit 200 and bevel file RACE LTR.

For better performance in racing, we advise refining the work of the grit 400 by light grinding for a high finish with the LD800.

Foire aux questions (FAQ)

    How often should I grind and polish the base edge with the drop files?

    At each sharpening, we advise you to do 3 to 4 round trips with the long grain 400 diamond file. This removes roughness.

    When there is noticeable damage, it must be removed or reduced with the long grain diamond file 200 and then finished with the long grain 400 diamond file to polish the underside of the edge.

    If structures (which are necessary for the proper functioning of the base plate) are under the edge, grinding them out with a long grain 200 and then 400 grit diamond file is essential for the proper functioning of skis and snowboards.

    Be careful, do not use long diamond files without lime guides!

    If file sharpening is necessary, is it necessary to polish with Roto-Finish and when using only Roto-Finish?

    The ideal is to file the first time and later to use Roto-Finish.

    After filing, there is no need to fine-tune with Roto-Finish.

    However, for the competition, especially if the snow is very cold and fine a polishing with Roto-Finish 400 then 800 will improve the glide.

    When you have skied for a few days on soft snow that has very little rounded edge, it is not necessary to file. You can then limit yourself to three or four trips with the Roto-Finish 400.

    When you've been skiing for a day or two on hard snow, you can sharp with the Twin Roro Concept, which consists of 10 to 12 round trips to the Roto-Finish 200 followed by polishing with the Roto Finish 400.

    This polishing will be done either by 6 round trips with the roto-Finish 400 set to a degree less than the Roto-Finish, or without changing the angle (same angle as the Roto-Finish 200) but with a dozen or so back and forth.

    If by 12 round trips to the RF200 you have not found the cutting edge, add some back and forth. If it is still not sharp it means that your edge is quite rounded and it is better to make a sharpening file.

    In general, if you don’t do frequent sharpening use the file.

    Do you have to round part in heel and spatula?

    This is a personal practice that also varies depending on the ski models and / or the quality of the snow. Some do not round, others little and others more and this on different lengths. In general, we avoid rounding skis slalom and personally I do not round in heel even when it comes to longer skis.

    For snowboards, it is advisable to round the front of the edge "front side" about 15 cm.
