The Sport-Thieme expansion spring set: perfect for practices and therapy centres
The Sport-Thieme expansion spring set consists of 4 expansion springs in strengths of up to 50 kg, up to 75 kg, up to 100 kg and up to 140 kg. The contrast of acceleration and deceleration makes the experience more intensive. For safety reasons, the springs should only be used in combination with screw-in snap hooks (2 hooks per spring, order at the same time).
