The M Part 40mm Threadless Stem Shim Adapter is a precision-machined alloy sleeve designed to adapt a 1-1/8 inch (28.6 mm) threadless stem so that it fits securely onto a 1-inch (25.4 mm) fork steerer tube.
This shim provides an easy, reliable way to fit modern 1-1/8" stems onto classic 1" threadless or quill-adapter steerer tubes, broadening your cockpit choices without changing the fork.
Features
- Function: Adapts a 1-1/8" (28.6 mm) threadless stem clamp diameter down to fit a 1" (25.4 mm) fork steerer tube
- Height: 40 mm stack height to match standard stem clamp bodies
- Lip Design: Features an integrated lip/collar at top to prevent the shim from sliding down the steerer during installation
- Construction: Precision CNC-machined aluminum alloy for exact tolerances and maximum clamping force
- Slot Design: Full-length split slot allows the stem clamp force to transfer evenly across the steerer
