Stacyc 19mm Mini Bar Conversion Kit The Stacyc 19mm Handlebar Conversion Kit is purpose-built to give your little ripper better grip and more control. The kit upgrades 12eDRIVE and 16eDRIVE bikes to the 19mm diameter Mini BAR with 28 smaller grip diameter. By reducing the grip diameter kids are able to fully grasp the handlebar the same way an adult rider grasps a traditional size handlebar. Better grip, more control, increased confidence.
