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.
