Portal Stem

A modern MTB stem with BMX influence. The Arise Portal MTB stem is fully CNC machined from 6061-T6 alloy, and utilizes larger BMX style 6mm hex bolt and our "Jaw Grip" clamping system ensuring your bars never move even when things get choppy. Available in 3 reaches including a super short 32mm option for super fast barspins and your choice of 31.8mm or 35mm clamping. Designed around the Radio AEON MTB gyro kit with plenty of space for a gyro plate under. Tested to destruction by the team for 3 years, this is one tough MTB stem, but then again with out "BMX background" would you expect anything less?
