The Tune Geiles Teil 4.0 stem in 85 mm length is a true classic among high-end stems – now even better! The revised clamping with four titanium screws distributes the clamping force evenly and optimally protects sensitive carbon handlebars. Perfect for road bikes, gravel, and XC applications.

Made from high-quality 7075-T6 aluminum and precisely CNC-machined, the stem combines high stiffness with a low weight of only approx. 115 g (85 mm). The conical design follows the force flow precisely – for optimal stability and direct steering precision. Compatible with all 1 1/8" steerer tubes and 31.8 mm handlebars.
