Shime, Handlebar Shim, 22.2mm to 31.8mm, 50mm

Carver Bikes Shime Handlebar Shim adapts a 31.8mm stem clamp to securely fit a 22.2mm handlebar, making it a practical solution when mixing components across city, BMX, kids, or older-standard cockpit setups. The 50mm shim length helps spread clamp force over a larger area for a stable, confidence-inspiring hold without forcing an incompatible fit.

• 22.2mm to 31.8mm fit - Allows a smaller-diameter handlebar to be used in a modern 31.8mm stem, avoiding an unnecessary stem or bar replacement
• 50mm clamp coverage - Distributes clamping load over more bar surface for consistent grip and reduced risk of localized pressure points
• Aluminum construction - Durable, corrosion-resistant interface built for repeated service and long-term use
• Stem parts compatibility upgrade - Clean way to standardize cockpit fit when swapping handlebars, stems, or completing a build with mixed standards
