      A solid part. Machined precisely, it fits my stem perfectly. A great way to convert a quill stem to a modern style stem without sacrificing rigidity.

          I scratch built one of these units just to see if it could be done. It takes a lot of engineering to get it right. I got it half right so I gave in and purchased this one. Problem solved 100%. This thing works great. I love it.

          Finally found a 1 1/8" adapter

          Comments about Nashbar Stem Adaptor:

          After some miscommunication with other online sellers, I finally got what I needed - an adapter for a 1 1/8" threaded fork.

          I'm giving it 4 stars only because of its length; you hit the minimum insertion line quickly when adjusting the rise. I guess most people cram these all the way down, but I like to run threadless stems flat for a traditional road look.

                I put the stem adaptor into a '70's Nishiki, because the dropped bars became uncomfortable. The adaptor fit perfectly, and allowed me to mount a mtn bike stem. Very useful, and the key component to my upgrade.

                      I have a fascination (and collection) of older bikes with quill stems - you never know when you are going to have a visitor! The aggressive angle of many older road bike stems just weren't conducive for working on the bike without removing the bar tape. I have looked for other similar products, but this is the best for my money!

                        I always thought of improving my old trek 1000, and this stem adapter came perfect. Now I can use 1 1/8 stems and .31mm handlebars like my others two newer bikes. I love it. I recommend it to anybody that wants to replace the old 1 inch stem to be able to use the new 1 1/8 stems.

                        I am using it to replace an old quill stem on my Trek 2100 as I couldn't find a quill with a short enough stem length. The stem adapter works just as I had planned.
