Excellent upgrade!
Delivery was fast and installation was completely fuss-free. The 4-piston brakes are a big improvement over my old 2-piston setup — stopping power feels stronger and more controlled. Great quality overall and definitely worth the upgrade!

Perfect. The included processing tools are also fine. There is no instruction manual, so it’s a good idea to read the description here carefully. There’s no need to refill the liquid, and the cable is long, so it’s convenient to set it up in your preferred position. This time I changed from 2 pistons to 4 pistons, and the performance has improved. Electric bicycles are heavy to begin with, so I think 4 pistons are better. The accent color also looks nice. The only question is how durable it is.
