ProsPerfectly machined and finished
I wanted a slightly less upright riding position on my hybrid so set about gathering up the parts. The quill stem adaptor had to be black to keep the look for the bars and stem I got were black. The adaptor, being 25.40mm diameter, needed a shim to allow the new stem to fit. The 25.40 to 28.60mm shim was the perfect solution. My bike looks and rides much better now.
Simple And Effective...:)

Prosease of use, price, looks
I am building a colnago C40 with a 1" fork steer, and used to match it to a modern 1 1/8" stem, works and looks brilliant :D

ProsBeautifully finished item.
Having to replace my old 1 1/8" threaded forks after nasty altercation with a Merc I bought myself some lovely carbon forks which had a 1" steerer stem. I easily sourced the headset but needed a shim to fit my stem and this was the best option.

ProsGood fit
Just what I needed. I was replacing an old quill stem 1" threaded headset with a threadless adapter in order to have more choice, but this gave a 1" stem. So a shim was required to use 1 1/8" stems. This worked perfectly, fitting the stem adapter and the stem very snugly.
Really Useful!

ProsPerfect fit, Very nicely machined, Problem solving
Just the thing to allow the use of a normal 1 1/8th stem with a 1 inch fork steerer. Really useful and allows a much greater choice when choosing a stem or allows the use of modern fair with an older bike. Ideal for that restoration! One thing to be aware of...you may still need to use a 1 1/8th top cap if you want to hide the shim. A 1 inch top cap allows it to peep through!
