Surly

22.2-31.8 Handlebar Shim

The Surly handlebar clamp shim increases the thickness of a smaller diameter handlebar, allowing it to be used with a stem with a larger clamp size.

• For 22.2mm handlebars with 31.8mm stems
• The same shim included with Surly Sunrise and Sunset riser bars
• Great for adapting BMX bars to mountain/road stems
