TCS Tension Control System - back ground information and key facts
August 7, 2025
News about products and offers
The correct tension on equipment such as uneven bars, horizontal bars, or rings is essential for safety, performance, and longevity. This is where the TCS device comes in.
1. Increase the safety of gymnasts
Apparatuses that are too tense or too loose can lead to dangerous situations – e.g., if the apparatus unexpectedly gives way or is too tense and the kinetic energy is not properly cushioned. The TCS measures the actual tension accurately and ensures that the apparatus is always set to the optimum range.
2. Consistent conditions in training and competition
In competitive gymnastics in particular, it is essential that gymnasts train under consistent conditions. Fluctuations in tension lead to different restoring forces or vibration behavior – this impairs technique and increases the risk of injury. The TCS ensures that every apparatus is always tensioned to the same level.
3. Simple and quick tension check
The TCS is compact, battery-powered, and easy to use. It allows anyone to check the tension regularly and objectively – without relying on feel or time-consuming readjustments. This saves you time and provides clear, documentable values.
4. Extended service life of the equipment
Over- or under-tensioning can damage the structure of the equipment in the long term. With the TCS, you can optimally regulate the load, which leads to less material fatigue and lower maintenance costs.
5. Standard-compliant work – even at competitions
If the club hosts or participates in competitions, the TCS is an important tool for ensuring compliance with FIG standards. It is particularly helpful to use the device as a binding reference when setting up with the help of volunteers.

Tension Control System (TCS) with NiMH batteries (AA)
FIG certified.
The new Tension Control System (TCS) with rechargeable NiMH batteries (AA).
It prevents from too low or too high tensioning of an apparatus thanks to the digital display.
When tensioning becomes too low or too high it is shown by means of a flashing light signal. Guarantees same tension characteristics of an apparatus and is quick to set up for athletes & coaches.
Supplied in a solid plastic case. Equipped with flashing light and start button. Displays the battery level + and the voltage in N. The device gives the tension in Newton a range from 0 N to 10.000 N with increments of 100.
Per one tensioned gymnastic apparatus is one tensioning measuring device necessary.
