RIDEA - Chain Hook Tensioners (Birdy) 鏈條張力勾

The QXE01 chain hook is installed in the tension pulley and keeps the chain tight while folding/unfolding and while carrying the bike, preventing any chain drops without increasing the folding/unfolding time. No more frame scratches from chain hits.

The QXE02 version keeps the same functionality as the QXE01 model, keeping the chain tight while folding/unfolding and while carrying the bike, but also adds an extra function as a chain tensioner to help preventing chain drops and chain stay hits while riding your Birdy.

*More colors are available as a customization option.
