Didn't end up using the shim, but it was well made and I would definitely purchase again if required

I have a 1inch threadless fork. Impossible to find a 1 inch threadless stem so this is necessary to use with a 1 1/8 stem. The smaller spacer worked for the 1 inch cantilever brake hanger that I also needed to replace with a 1 1/8.

クロモリロード用にステムを探していた所、ほとんどのステムのコラム経が２８．６でノーマルサイズ２５．４で好みの仕様のステムが無く愕然としていた所こちらの商品を知り救われました。取り付け問題なく好みのハンドル＆ステムが付けられて満足しています。国産パーツかと思っていたのですが中国？台湾？からの発送で約２週間位かかりました。
