Radio Bike Stem Portal

A modern MTB stem with a BMX influence. The Radio Portal MTB stem is fully CNC machined from a 6061-T6 alloy, and uses larger 6 mm BMX style hex bolts and our "Vice Jaw" clamp system, ensuring your bars never move, even when things get hectic. Available in 3 lengths, including a super short 32 mm option for ultra-fast bar rotations, and your choice between a 31.8 mm or 35 mm clamp. Designed around our new MTB AEON gyroscope kit with plenty of room for a gyroscope plate underneath. Tested to destruction by Niklas Tilk and the Radio team for 3 years, this is a truly robust MTB stem, but with a BMX background, you wouldn't expect anything less, would you?
