tune Geiles Teil stem 4.0 OVERSIZE 8°

Geiles Teil 4.0 - 99,3 gram
The most memorably named Tune item

"Geiles Teil" literally means "Horny Piece"
So naturally, it’s super-stiff and available in many lengths…
But it’s also as reliable as it is beautiful, and as firm as it is elegant.
A bonafide superstar amongst the aluminium stems of the world, it’s currently in it’s fourth iteration, benefitting from next generation youth, and all the lessons learned from our experience of previous versions.

Each one is artfully milled by our new CNC machine (with a milling time of 25 minutes per unit) from a single piece of the highest quality aluminium.The conical shape, both inside and out, corresponds exactly to the variations in force running through the stem, making it as light as is possible, and as strong as is necessary.
Continual evolution and optimisation has turned the original ‘very good’ stem, into an almost perfect product, proved by the VR-3 Max stress test (the toughest in the world).

At just 99g, and 85mm in length, our titanium screw equipped version offers the best combination of stiffness, weight and safety.
The precise and balanced clamping of carbon fibre bars and fork shafts means that both are held firmly and evenly, but adjustment is also precise and easy.
The geometry is ideal for 29er and 650B mountain bikes.

So perfect in fact, that mountain bike World Championships – and Olympic Games were won with our „Geiles Teil 4.0“!
Available in both 8 and 17 degree versions
The flip-flop mounting of the 8-degree version on the road bike results in an angle of approx. 0 degrees to the ground.

Available in all Tune-anodized colors here in our shop!
