Review on MTB Bicycle Fork Stem Extender Handlebar Riser Adaptor - TRIWONDER Aluminium Alloy Head Up Adapter by Robert Worlds

I like the handlebar extension. I put it on my mountain bike because the handlebars were too low and it cost less than new bars. I took it out on a fairly rugged trail the next day and it held up fine. My only complaint is the long bolt that screws down into the neck does not have any way to be tighten. It has no hex slot, screwdriver slot, square head for wrench or anything. Its just a rounded head and you can only run it down with your fingers as tight as you can. I cut a slit in it with a dremel tool so I could use a screw driver. Strange how such a obvious flaw could be acceptable. Good buy if your comfortable with modifing.
