Rotor SX Stem 31.6mm

This stem's weight ranges from 103g to 119g 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 SX has a two 2-bolt faceplates, bigger dimensions and 31.6mm clamp with +/-2.5 degrees of tilt compared to the SL that has a 2-bolt faceplate and +/- 7.5 degrees of tilt.
