Geoff Slattery Signature Top Load Stem from Eclat. Using a traditional, solid classic topload design, Geoff’s stem features 30mm rise and a wide faceplate with larger head bolts to allow the bars to be really clamped down and prevent them from ever slipping. The Slattery Stem also utilises the STC (Shark Tooth Clamping) system, which allows the knurling on the bar to bite into the stem even harder and keep them in place, even after the burliest of drops or big gaps. ###section### Product Specs TYPE: Top Load REACH: 51mm RISE: 30mm CLAMPING DIAMETER: 22.2mm WEIGHT: 367g
