Stem Shim 1 Inch - 1 1/8

This stem shim is a straightforward adapter sleeve that allows you to use a 1 1/8 inch threadless stem on a 1 inch steerer tube. Slipped over the steerer before you clamp the stem, it increases the outside diameter from 25.4 mm to 28.6 mm, ensuring the stem tightens evenly without crushing or slipping. It’s an elegant solution for upgrading to a modern stem on an older fork, perfect for city, touring, and road bikes where you want more options for stems without the need to change the fork.
