Rotor S1 Stem

This stem's weight ranges from 99g to 118g depending on the length you chose. How can this be? Well, Rotor developed what they call DTT (Double Thread Technology). With DTT, each end of the bolts use a different thread pitch. In addition, mating parts of the bolt are pulled together by their respective threads so there is no head on the bolt and there is less localized clamp pressure so the parts no longer need to be reinforced there. The quality machining of stem is superb and laser etching on the anodized finish a classy look. The oversized dimensions make the stem look sleek and feel rigid.
The SL has a 2-bolt faceplate and +/-7.5 degrees of tilt compared to the SX that has a two 2-bolt faceplates, bigger dimensions and +/- 2.5 degrees of tilt.
