Review on 🚴 ZUKKA Bicycle Fork Stem Extender, Adjustable Handlebar Stem Riser, Aluminum Alloy Bike Stem Riser, Head Up Adapter 1-1/8 inches for Bike Neck Extension by Nick Nunez

I can now sit upright on my bike. Robust construction. Assembly: Tighten the riser and stem connecting screws only slightly, they must be able to be moved easily. Align and hold while tightening the top bolt just enough to eliminate any play in the headset bearings. If you find that excessive torque is required to remove this play, it is because the inside of the riser is pressing against the top of the steering column. In this case, place a short spacer under the riser/extension.
