The item arrived quickly and was well packaged. It matches the description. This adapter is very practical for mounting a modern stem on a 90s mountain bike. I recommend it.

This adapter works great. I’ve used this one a few times now and am quite pleased with it. It’s buried in between the stem and stem spacers. As you can see this stem is doing its job quite well on my new build.

This adaptor works well. It was a little tight to get into the frame but nothing a rubber mallet couldn’t help with. I wish the top cap was guaranteed to be the same color as the rest of the item. I ordered a black adaptor and the top cap was silver.

Steering pen slips on this adapter no matter how tight you turn it. tried it on another bike and the problem disappears so it is the adapter.
