The Salt Junior Top Load Stem was designed for 16" & 18" bikes while being perfect for flatland riders wanting a shorter reaching stem. It's built from 6061-T6 alloy using a forged process to create a durable & strong stem, with cutouts throughout to reduce weight without sacrificing on strength. The clamping area utilises STC (Shark Tooth Clamping) giving as much bar grip as possible. section Product Specs TYPE: Top Load REACH: 40mm RISE: 33mm CLAMPING DIAMETER: 22.2mm WEIGHT: 246g (8.72oz)
