Bicycle handlebar height adapter, 28.6 mm stems, aluminum bicycle head tube extension

【Made of Aluminum】The bicycle fork extension is made of refined 6061 aluminum alloy.

The height of the extension can be adjusted by changing the number of spacers, effectively reducing waist pressure and making cycling more relaxed. 【Adjustable Height】; The handlebar adapter is equipped with 5 spacers (5 × 10 mm), increasing the height by 10 cm.
