Geiles Teil 4.0

Recognized, super stiff and available in many lengths! The stem Geiles Teil 4.0 is uncompromising. Our winner in the category weight, stiffness and safety. The conical shape, inside and out, allows a perfect power flow and high stiffness.

The design of the handlebar clamp is unprecedented in this form. In addition to a perfectly fitting clamp, the stem Geiles Teil 4.0 also offers easy assembly.

Thanks to the four-point clamp with titanium screws! Suitable for aluminum as well as carbon handlebars made.

You love it big? No problem! Even with oversizes with a clamping of 31.8mm the Geiles Teil 4.0 holds your handlebars reliably.

Here is milled from the solid. A full 25 minutes running time for each individual stem on our CNC machine. You get artistic milling work from the highest quality aluminum.

The proof for our perfect construction was the bravura passed “VR-3 Max” test. The test is the hardest load test in the world!

Full safety and stiffness at just 112g on a length of 85mm.

The geometry is ideal for 29 and 650B mountain bikes.
So ideal that mountain bike pros can win World Championships and Olympic Games with our “Geiles Teil 4.0”!

Definitely a superstar among the aluminium stems of the world. He is already in the fourth generation “his husband” – and is still absolutely youth-free!!!
