The Portal Stem is a modern MTB stem with strong BMX influence, built for riders who demand maximum control, strength, and reliability. Fully CNC machined from 6061-T6 aluminium, the Portal Stem uses oversized BMX-style 6mm hex bolts and Arise’s proven Jaw Grip clamping system, ensuring your handlebars stay firmly in place even in the roughest conditions.

Available in 32mm, 35mm, and 40mm reach options, including an ultra-short 32mm reach for fast barspins and responsive handling, the Portal Stem suits everything from dirt jump and slopestyle to enduro and downhill riding. Designed specifically around the Radio AEON MTB gyro kit, it offers ample clearance for a gyro plate underneath, making it ideal for riders running rotor setups.

After three years of real-world team testing and laboratory testing that exceeds MTB ISO 4210-5 standards, the Portal Stem delivers BMX toughness with modern MTB precision.
