ODIER Bike Headset Spacer Set – 6Pcs Aluminum Alloy Bicycle Stem Headset Spacers for 1 1/8-Inch Stem – Compatible with MTB & Road Bikes – 2mm, 3mm, 5mm, 10mm x 3 – Black Review

They work great and are priced right, but the outside diameter is smaller than the spacers I bought at the bike shop giving my stem a slightly "offset" look with the smaller diameter spacers at the top Has. Purely cosmetic problem. The fit and finish (other than OD as mentioned) is great.

I've seen a lot of crappy aluminum spacers over tears, Giant springs to mind, but these are really good. Sure, they don't make your bike faster or lighter, but they have smooth micro-machining, beveled edges, and an anodized finish that's much better than typical OEM powder coats. worth $$.

You are great. Beautiful and shiny. I really only needed a small spacer for the bike I was building, but when I took it apart and noticed that the existing spacers were some weird non-metallic composite material, I replaced them all with these spacers. Exactly as advertised, brilliant finish and light enough to easily replace those plastic gaps I had.

I've only used the 5mm and 2mm sizes. The stem had to be raised a bit as the fork tube was maybe a millimeter higher than the top cap to fit properly, 2mm was perfect. So I removed the "extra" 5mm that was on the bike and added 2's and 5's for a clean, uncluttered look. I don't know what batch people got that was loose or sloppy on the fork tube, they fit very well. They only seem to be about 28.6 ID

Just what I need to replace stems on a Cannondale Quick 6 and Giant road bike. Before spacers were used, a carbon fork could not be tightened when installing a new stem. Thanks to the wide variety of spacer sizes, I was able to make up the difference and get the perfect result. They fit perfectly on a threadless rod (the diameter matched perfectly). If you're replacing a stem on a bike for a better fit, make sure you get some of these spacers as well. If I hadn't read the questions and reviews…
