Fat-Cat Bike Handlebar Riser Bicycle Fork Stem Raiser Extender Head Up Raiser Aluminum Alloy

Very good

Excellent

I had to buy two allen screws because mine only came with one and that one was1/4 inch too short.

Could not use this. Screw holes were not threaded, so could not tighten.

Threads stripped out.Had to drill out the holes and rethread them

Use to raise the stem on an e-bike.
