Alloy Quill to Ahead Stem Adapter 22.2mm 20.8mm 28.6mm

Main Description

Upgrade your bike cockpit with the Alloy Quill to Ahead Stem Adapter. This versatile adapter converts quill stems (22.2mm or 20.8mm) to a 1-1/8" Ahead-style stem, letting you customize riding position and quickly swap setups. Made from 6061 aluminum alloy and heat-treated for high strength, it stays light at about 100g while delivering solid stability. The anti-slip pattern enhances grip, while the compact size (120 x 30 x 30 mm) and adjustable clamp diameter (28.1–29.5 mm) fit common handlebars. Height ranges 56–65 mm to fine-tune your cockpit stack. Origin: Mainland China.
