Two things about carbon fiber that can not be denied. Durability and of course, lightness. Who would of thought, as an extra bonus, it would be so fortuitous in our daily diet? Which of course gives it a "WOW" factor of at least an eight! Wouldn't you agree?

The package covered both my mtb and my road bike. I lubed in between just to keep the ends from fraying, but probably overkill. These things shaved about 15g from each bike, which is just a bit more speed increase than flame stickers. They do look pretty darn slick though. Matte looks really good, not too pronounced and just enough for someone getting close to notice.Will update if they don't stand the test of time.

Changed out my stem and I didn’t have the correct spacers. I ordered these and wasn’t disappointed. There were enough sizes to fill in the gaps and get my stem mounted correctly. I probably didn’t need carbon fiber spacers since I didn’t have any other carbon fiber on my bike, but couldn’t resist the price. They seem to hold up fine and do their job.

A bit thicker than they need to be. But the do the job. Heavier than the ones that came on my specialized mtb.

The reason why I purchased this adapter kit is because I recently swapped my front forks and then discovered that I had a lot of space that can actually be unsafe. So therefore I went online and purchased this adapter kit and it works great and looks good!

Very nicely finished. They match to my matte 3k parts extremely well. And when lined up properly it is very difficult to see the seam between two spacers. I plan to purchase all the other finishes, as well, as we go through these in the shop like candy. Highly recommended!

The style is legit and the different sizes allows me to use them on multiple bikes. Plus at less than $10....WIN WIN Situation!
