The 4-stage development and testing process for TATZE pedals!

Every innovation aims to improve the functionality of a product. At TATZE, uphill and downhill performance is to be combined in one product and thus the potential of modern trail bikes can be fully exploited in any terrain.

The improvement of the function is the first priority, but immediately afterwards questions arise about weight, stability, impact resistance, durability and design. So it's about producing innovative, high quality and stylish pedals. 

In order to be able to achieve all of these goals, TATZE has the following 4 development and quality assurance levels:

1. SIMULATIONS: All PAWS are set up and simulated as a 3D CAD model. Tension peaks in the pedal can be localized and impact simulations reveal potential break points.

But as Goethe said, "all theory is gray" because of this ...

2. PAW TEST STAND: According to the current ISO standard, every mountain bike pedal must pass three tests. All tests can be carried out on the specially designed TATZE test stand with more than twice the standard load. So it is checked exactly according to the standard arrangement, but the loads are set significantly higher.

In the Impact test (side B) the pedal is used the most, because a hardened steel wedge falls directly onto the clamped pedal. In doing so, it must deform but not break and the bearing must remain smooth. This test ensures that the pedal does not break or stiffen even in extreme situations.  
The static strength test (side A) is comparatively simple, but the pedal must return to its original position after the load. So there must be no permanent deformation. In practice, it is not uncommon for an axis to show a slight asymmetry after high loads. 
Finally there is the dynamic strength test (side A)which is nothing more than a warehouse check. The PAWS rotate at a load of 90kg for 20 hours at 100rpm. A total of 120,000 revolutions to prove the wear resistance.

3. TEST DRIVES:
When the prototypes have passed all tests on the test bench, they are screwed to the bike. All ideas for TATZE innovations were created on the bike to improve performance on the trail. It is therefore as clear as day that we undertake extensive test drives at all stages of development. Erich Wieland, one of the best downhillers in the Alpine republic, is responsible for testing the Paws at the absolute limit. The world cup proven rider has the task of destroying the pedals as much as possible, which he has not succeeded so far!

 4. CERTIFIED TESTING INSTITUTE: Even if after levels 1-3 we are absolutely sure that our pedals can cope with far more than the required standard loads, it is always good to check the test professionals from the Zedler Institute, where many tests by renowned bike magazines are also carried out to let. Only when we have the official seal of approval in our hands are the PAWS delivered. 

It is our aim to produce the best possible bike pedals, which is why we make great efforts to combine innovation, quality, safety and design in our products!
