When it came time to design a new stem, the Rotor team threw everything they had at the project. The result? Our new S3x stem. Astonishingly light (less than 100g for the 90mm version), yet ridiculously strong as well. Like our S3x handlebar, the stem is tested to Germany's most demanding certifcation, the EN14766 standard. When the machine doubled the number of CE required fatigue cycles, we finally shut the testing machine off!

The S3x uses four conventional titanium bolts on the face plate for easy installation, and a single DTT bolt for the steerer clamping interface. A single DTT steerer bolt generates tightening forces equal to two standard bolts, whilst simplifying the clamping force distribution and eliminating the need for additional reinforcements in the clamp design. Not only that, but we designed the S3x stem with carbon steerer tubes in mind. An increased steerer tube clamping area reduces stress and deformation of lightweight carbon steerer tubes.
