Mountain Bike Headset Spacers 1 1/8 Inch BMX MTB Bike Stem Parts Bicycle Handlebars Riser Accessories 2 3 5 10mm 6 Piece 6061 Aluminum Alloy (Black)

They seem to be well made and the sizes that were advertised were accurate. I only just received them but they fit my mtb nicely and are working just fine so far.

Quality is good. No complaints. All the sizes match up perfectly to each other. Well made.

Exactly what I needed to change the stems on a Cannondale Quick 6 and a Giant road bike. Before using the spacers the carbon fork could not be be made tight when the new stem was put on. With the great size variety of the spacers, I was able to make up the difference and get it perfect. Fit perfectly on the threadless stem (diameter was perfect). If your replacing a stem on a bike for a better fit, make sure that you also pick-up some of these spacers. If I hadn't read the questions and reviews on this product, I would have never known there was such a thing. For a couple of bucks, I was able to fix two bicycles--not bad.Very pleased with the product, cost and received quickly with Amazon Prime.

Just as advertised. You get 1x : 2mm, 3mm, 5mm, and 3x : 10mm Nice black glossy finish. The only problem is that they are slightly larger than the steerer tube. But, they look nice and work fine until I can afford to get some cane creek interlocking spacers for my creek 40 series headset.

Perfect fit and look. These are the same diameter as my bontrager RXL stem and look amazing. Very nice finish, they stack nice and flush to one another. Grab them, do not spend the $$ for FSA, over priced IMO, these are better quality than my FSA polycarb spacers.

I ordered these spacers with a new stem for my road bike. I returned them, because I was able to use the previous spacers. But they were well made and fit perfectly. They are a great value if you need them.

great spacer set works well and was as described just right size spacer to work out your stem length had trouble in past with others breaking and having movement in head thought aluminium would be the way to go have had good luck with these in the past

They're great. Nice and shiny. I actually only needed one little shim for a bike I was building, but when I pulled it apart and noticed the existing spacers were some kind of weird non-metal composite material, I replaced all of them with these spacers. Exactly as advertised, shiny finish and light enough to easily replace those plastic gappers I had.

It's perfectly fitted in my bike the steerer width is 28.6mm or 1.1/8

Well made with a nice black finish & fit was great.

ok

Good
