Zipp SL145

The SL145™ stem is a perfect example of the determination 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 the Ducati® MotoGP racing program, and a stainless steel insert within the anodized black faceplate.Simply put, the SL145 was not easy to design and it’s 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 135 g (100 mm length). It’s available in lengths from 80mm to 130mm with /- 12 degree angle and 31.8 mm clamp.Please note the SL145 stem does not ship with a stem top cap. A matching cap may be purchased from our web store or any Zipp dealer.
