We offer various levels of spring tension for each finger, while adhering to a balanced standard size for the casing. Additionally, all springs share the same length for versatile use. These sizes are optimized for adults and even teenagers. By incorporating lighter springs on weaker fingers (such as the pinky finger), an individualized balance is achieved, facilitating a smooth range of motion.

Even individuals with larger hands and fingers will find ample space due to the lateral flexibility of the springs. While we currently do not have an ideal product for small children's hands, we are committed to developing a suitable solution in the future.

During exercise, the pressure resistance may decrease slightly. This reaction is supported if you keep the spring pressed, which you should avoid if possible. After your workout, the spring relaxes again and provides you with your usual resistance for the next session.

he springs are manually inserted into the casing and undergo a 100% test for their compression behavior. Long-term compression testing of the springs is conducted on a sampling basis.

The behavior of the springs is such that new springs might experience a slight reduction in length (approximately 1 mm) after initial frequent compressions (around 50-100 times). However, after this initial change, they remain stable in that length. This effect is slightly less pronounced in the slimmer, gray springs (light), which can occasionally result in a minor offset between the light springs and other springs. This is completely normal and is attributed to the technical material properties.

The slight length reduction does not affect the function or quality of the spring; it's a natural initial process.

Our springs are exceptionally resilient and long-lasting. The spring strength is based on the typical behavior of springs. For instance, we measure the maximum compression force of the spring as a snapshot while pushing it to the deepest endpoint. When springs are held in the compressed position, they might experience a slight decrease in resistance over the holding period. However, after releasing the compression, the spring tension rebuilds, allowing for the measurement of maximum compression forces once again.

Naturally, improper handling, such as excessive elongation of the spring or prolonged exposure to UV radiation, can influence the spring properties and longevity.

The color always corresponds to a specific spring tension - for instance, gray indicates light, blue signifies medium, and black/white represents strong. In the case of special editions, new colors might be introduced, but the primary colors gray, blue, and black consistently maintain a clear correlation to compression strength.

Training is at its best when the springs are fully relaxed at each compression rate. This gives you the best training effect and the pressure resistance of the spring also remains more constant. If you stretch the spring forcefully, this can damage the spring. Keeping the spring pressed also damages the elasticity of the spring and can have a lasting effect on the behavior.

Of course, we offer all standard spare parts either through our online shop (e.g. compression springs of varying strength) or directly upon request. For limited availability special editions, it might occasionally happen that dedicated spare parts are out of stock.

During the initial phase, the Ti-Hand will be exclusively available on our website www.tirock-sports.com through our online store.

We're looking forward to your purchases and equally excited to hear about your experiences and feedback, which hold great importance to us.

Apart from our own online store, starting from September 2025, the Ti-Hand can also be found in select retail outlets.

Feel free to reach out to us, and we will gladly provide information about potential retailers in your vicinity.

Die Federn sind aus hochwertigem technischem Kunststoff hergestellt, der in technischen Anwendungen aufgrund seiner sehr guten Gleitlagerfähigkeiten geschätzt wird und funktioniert. Dennoch können leichte Geräusche auftreten, welche Kollegen während der Arbeit oder die Familie / Freunde beim Fernsehen stören könnten.

Leider lassen sich diese Geräusche nicht vollständig vermeiden. Das Reinigen der Feder mit einem Stofftuch (zwischen den Schenkeln und den Federlamellen) kann die Nebengeräusche reduzieren, jedoch nicht vollständig und nicht immer. Im Allgemeinen beeinflusst auch die Farbe der Feder die Entstehung von Nebengeräuschen. Es hat sich gezeigt, dass schwarze Federn in den meisten Fällen kaum Geräusche erzeugen.

Generell gilt: Nebengeräusche sind bei gleitenden Federvorrichtungen üblich. Unser Fingertrainer erzeugt jedoch wesentlich weniger Geräusche im Vergleich zu konkurrierenden Produkten mit Stahlfedern.

Für diejenigen, die gerne neben der Arbeit oder beim Fernsehen mit dem Fingertrainer trainieren und dabei ihre Familie oder Kollegen nicht stören möchten, gibt es einen kleinen Trick bzw. Tipp, wie mögliche Nebengeräusche deutlich gedämpft werden können. In dem folgenden Video findest du eine Anleitung, wie du in weniger als 3 Minuten dämpfende Elemente herstellen und einbauen kannst. Probiere es zuerst bei einer Feder aus und überzeuge dich von der Veränderung.
