      Comments about Nashbar Stem Adaptor:

      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.

                  Comments about Nashbar Stem Adaptor:

                  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.

                    Comments about Nashbar Stem Adaptor:

                    This made it very easy to convert my dad's old road bike into a pretty cool and comfortable single speed commuter bike. As in the other reviews, the stem is very short and does not leave much room for raising the height of the handle bar. In my case, it did not matter since the head tube on my frame is very long on my bike so handle bar height was not an issue for me. Bottom line, it works!!
