This patented T-shaped tooth design of the ChainFlow® 3D technology ensures that the chain does not drop off the chainring, even in the muddiest conditions. This provides superior chain retention. The Miranda chainring with 44 teeth is specifically designed for 1x11/12 speed bicycles. It is universally applicable and suitable for e-bikes. With its black color, the chainring matches every bicycle.
