I'm using aftermarket parts, but it can be made with a brake stay ⭐️ Also, the gear cover is not included. New product!! Reusable gear cover fixing carbon ⭐️ Gear covers are consumables, isn't it troublesome to remake them? This product can be reused many times just by inserting it ⭐️ It strengthens the rigidity of the gear cover and also optimizes the contact pressure of the motor ⭐️ Easy design, just cut a part of the cover with nippers and attach it ⭐️ Haven't you ever felt that it's slow with the same voltage and settings? Contact pressure is often overlooked, but it's rock solid just by attaching it ⭐️ If you don't attach the battery cover, you will need to attach some scraps, but we will include instructions ⭐️ 14
