Applying ROTOR's new DTT Evo Technology in the faceplate and the steerer clamp of the already reliable S1 Stem we are able to achieve an incredible clamping force. The tightening tolerance has been readjusted to ensure a correct and perfect distribution of the clamping force. DTT Evo bolts have been redesigned with a new dual-thread pitch design and use a T25 Torx head. Using a T25 design allows for reliable tightening without rounding out the head of the bolt, in turn, we ensure reliable clamping regardless of the handlebar in use.
