Knowledge Popularization About Roller Skating Tool Holders

Tool holder system High and low rack system

The heel of the high-low shelf system is relatively high, and the ankle position of the upper shoe adopts a forward-leaning design.

The feature of this design is that it can guarantee the forward pressure and kinetic energy, which makes the running start faster and more stable, and the gliding continues to be strong, but it is limited in jumping.

Most of the tool holders of roller skates now use this system. Such as flat shoes, speed skates, FSK shoes and so on.

The length of the tool post refers to the distance between the axis of the first and last wheel, generally in millimeters.

Common methods for judging the length of a tool holder:

1. Use a ruler to measure the distance between the centers of the first and last nail piercing holes.

2. The diameter of the two wheels in the middle of the tool post plus the radius of the front and rear wheels, plus the three gaps between the wheels, is the length of the tool post.

PS: Usually the wheelbase is 1mm. When the tool holder and wheel configuration are different, the wheelbase may not be 1mm.

common parameters

219/231/243/255mm

9.2/9.8/10.5/12/12.4/12.6/12.8/13.2 inches

Of course, commonly used tool holder lengths generally default to commonly used wheel configurations.

For example, 219mm is usually a banana rack, which can hold a maximum of 4*72mm; 231mm can hold a maximum of 4*76mm; 243mm can hold a maximum of 4*80mm,

9.2 inches are usually 3*90mm speed skating knife holder for children, 9.8/10.5 inches are 3*100/3*125mm speed skating knife holder for adults and so on.

The specific tool holder length and the size of the largest configurable wheel need to be analyzed according to the actual situation.

In addition, the speed skating tool holder and wheel configuration are different, and the performance is also different.

features

The long tool post has high stability and better battery life; the short tool post is more flexible and easy to control.

In order to ensure that the high-end professional speed skating tool holder can fully exert the continuous movement of the standard three-wheel and four-wheel,

And without affecting the overall stability, the center of gravity of the tool holder is lowered as much as possible, so professional speed skating tool holders are generally longer

For another example, the downhill tool post can accommodate five 90mm wheels, the tool post has a low center of gravity and high stability, and can better cope with downhill terrain and road conditions.

The tool holders for casual street brushing, flat fancy and other projects are relatively short. In addition to ensuring the stability during use, the flexibility is enhanced and easier to control.
