The Éclat Abyss is a high-performance BMX sprocket for freestyle bikes. It comes in 25T and 28T versions. Pick a larger sprocket with more teeth if you wish to gain higher top speeds. However, if you want more effortless pedaling and better acceleration, then the smaller sprocket should be your choice. This Éclat sprocket is designed with a 24mm bore and a bolt drive hole, but thanks to the included adapters, it is suitable for 19mm and 22mm mounting as well.
