Good

Too costly it's only alloy not carbon, can buy carbon in less than half price, not recommended on this price.

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

ok

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.

I've seen plenty of crappy aluminum spacers over the tears, Giant comes to mind, but these are really nice. Sure, they won't make your bike faster or lighter, but they do have a smooth micro finish, chamfered edges and an anodized finish that's leagues better than the typical OEM powdercoated ones. Well worth the $$.

These work great and the price is right, but the OD is smaller than the spacers I got from the bike shop, so my stem has a bit of "stepped" look with the smaller diameter spacers at the top. Purely a cosmetic issue. Fit and finish (other than OD as mentioned) is great.
