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

Big tip: If you think your cables are too short (mine were not) slip your handlbars over it BEFORE putting it on. Saves about 2 inches of initial raising. It was a very easy install. The weight of it was more than I thought, as some reviews said otherwise. Pretty solid. I had no trouble tightening it, or over tightening it. It was a very, very tight fit and I had to hammer it on down with a rubber mallet. Caution: If it is tight on yours, be sure it is lined up before slamming it down. It is very hard to twist off. I did not twist it off to realign it, just used a piece of wood and hammer. It does not matter anyway if this is out of alignment, as that only affects the look. (Of course you align the handlebars!) You can use all the spacers, and tightening your handlbars with a little space is below the top is fine. My bars had good bolts and grabbed. Like I said, don't worry about over-tightening and stripping it. Just do it hand tight, and a small amount more. If it does strip, no big deal. You can buy bolts and nuts that would go through just fine at home depot. But it was a tight fit on mine and would probably hold without even tightening! But I would not recommend this! Anyway, it is a solid deal. And get this: Once this is in place, if you want to go even higher, NOW you can buy the adjustable ones and install easily over this one.I might do that in the future.
