Tatze

What is special about TATZE?

Tatze is known for independent developments around the topic of pedals. TATZE wants to combine the uphill and downhill performance in one product and thus fully exploit the potential of modern trail bikes in any off-road situation. Important here is weight, stability, impact resistance, durability and design. So it's all about producing innovative, high-quality and stylish pedals.

To be able to achieve all these goals, TATZE has the following 4 development and quality assurance stages:

1. SIMULATIONS: All TATZes are built and simulated as a 3D CAD model. During this process, stress peaks in the pedal can be localized and impact simulations reveal potential fracture points.
2. TATZE TEST STAND: According to the valid ISO standard, every mountain bike pedal must pass three tests. All tests can be performed on the specially designed TATZE test stand with more than twice the standard load. So it is tested exactly according to standard order, but the loads are set much higher.
3. TEST DRIVES: When the prototypes have passed all the tests on the test stand, they are bolted onto the bike. All ideas for TATZE innovations are created on the bike to improve the performance on the trail. Therefore, it is as clear as day that we undertake extensive test rides at all stages of development.
4. CERTIFIED TESTING INSTITUTE: Even if we are already absolutely sure after stages 1-3 that our pedals can withstand far more than the required standard loads, it is always good to let the test professionals from the Zedler Institute, where incidentally also many tests of renowned bike magazines are carried out, to check again. Only when we have the official test seal in our hands are the TATZEN delivered.

What is tested in the test procedure?

In the impact test (side B), the pedal is subjected to the greatest stress, because a hardened steel wedge falls directly onto the clamped pedal. The pedal must deform but not break, and the bearing must remain flexible. 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 condition after the load is applied. In other words, there must be no permanent deformation. In practice, it is not uncommon for an axle to have a slight asymmetry after high loads.

Lastly, there is the dynamic strength test (side A), which is nothing more than a bearing test. The TATZEN rotate at 90kg load for 20 hours at 100rpm, a total of 120,000 revolutions to prove wear resistance.
