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