Black Ops 4 Bolt Alloy BMX Quill Stem, 21.1mm

Great find!! Small for my bike though, should have checked the stem size first.Bought for cruiser bike with ape hangers. Used the little gray piece from original stem for a snug fit for now. When removing your original stem, the size is stamped at the base of your quill stem. 21.1 but needed 22.2.

Mi son (10) really abuses his bike. He is a big boy, and loves to pop willies. Well, so far, this has really held up. And it beats having to buy a whole new bike, which I refuse to do.

Was donated a kids bike that was rusted over, so I fully customized it and replaced some of the really bad parts. This was one of the parts I lost during the breaking down of the bike (of course I lost a part), so I picked this up. This is excellent quality, fit perfect as described, and looks great on the bike. Very easy to install as well! (This was actually the first BMX bike I have ever put together). That being said, I am very happy with the purchase thus far and would definitely recommend this slick looking Quill to anyone looking to amp up the look of their BMX bike!

This is a well built gooseneck. I purchased this to replace a diamondback gooseneck that failed. This one went right in and it looks like it belongs on the bicycle.

Very happy with this stem for the money, for use with 7/8" handlebars.The 4 bolt clamp keeps handlebars from moving while curb hoping and jumping.NOTE: Advertised as " 1 inch " stem. Not correct.Actual measurements are:21.1mm quill size and 22.2mm (.872") clamping size (which equates to 7/8")!!!!!Note to self. This stem is to be used with handlebars that are22.2mm (.872") which are 7/8" diameter.One inch handlebar diameter is too large to fit this stem!

This was added to my beach cruiser. It holds my ape hanger handle bars on really well. It was very easy to install.

Works, looks ok, good price. Replaces a cheap gooseneck that kept slipping. Would not hesitate to get another.

I was a little disappointed that the center bolt is a hex instead of an allen. The hex cap/allen would have been better looking. Also the part that squeezes up into the sleeve inside the post is pot metal. It should have been something a bit sturdier for long term. But all in all its a good looking addition.

perfect fit & fast service :D

works well as a replacement on my kids bike, seems fairly strong and well built.
