Geoff Slattery Signature Top Load Stem from Eclat. Using a traditional, solid classic topload design, Geoff’s stem features 30mm rise & a wide faceplate with larger head bolts to allow the bars to be really clamped down & 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 & 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: 25.4mm WEIGHT: 367g/12.9oz
