The SL145 stem is a perfect example of the determination that our engineers display when faced with a challenge. It requires 50 sections of hand-wrapped carbon cloth, titanium bolts sourced from the same Italian producer used by Ducati's MotoGP racing program, and a stainless steel insert within the anodized black faceplate.
The SL145 was not easy to design and its not easy to produce. But the result is the stiffest, strongest all-carbon stem available as verified by EFBe Laboratory. The SL145 is a rock-solid connection from bars to bike that weighs just 135g (100mm). Its available in lengths from 80mm to 130mm. +/- 12.5 degree angle and 31.8mm clamp.
