Good

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

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

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

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.

ok

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.
