About this product

The Portal Stem is a modern MTB stem built for riders who demand maximum control, strength, and reliability. Fully CNC machined from 6061-T6 aluminium, it features oversized 6mm hex bolts and Arise's proven Jaw Grip clamping system for rock-solid handlebar retention in the most demanding conditions. Available in 32mm, 35mm, and 40mm reach options, it suits dirt jump, slopestyle, enduro, and downhill riding. Designed around the Radio AEON MTB gyro kit with full clearance for a gyro plate underneath. After three years of real-world and laboratory testing exceeding MTB ISO 4210-5 standards, the Portal Stem delivers precision and durability you can count on.
