The ChainFlow® 3D technology is an innovative solution for derailleur bicycles with 11/12 gears. The patented T-shaped tooth design prevents chain drop during shifting. With a taller and narrower tooth profile, the chain stays firmly on the chainring, enabling smooth shifting. The ChainFlow is designed to keep the chain on the chainring more effectively and is suitable for 11-speed systems in combination with a single chainring. With the ChainFlow 3D, with an even taller and narrower tooth profile, the chain is held on the chainring even more effectively during shifting. This version is suitable for derailleur bicycles with 11/12 gears in combination with a single chainring. The ChainFlow chainring is made of high-quality aluminum and has a black base color. With 38 teeth and 4 arms, the chainring offers optimal performance and durability.
