WippermannConnex E-Bike Sprocket for Bosch Drive 17 Teeth Chain Rings Silver One Size

I wanted a larger front sprocket on my Cube Reaction Race ebike (Bosch CX motor) to get a bit more road speed in the higher gears, and so I bought this one with 17 teeth. Fits and works fine.To remove the lockring I used the IceToolz Unisex's M801 Lockring Tool, which is much cheaper than the official Bosch tool. Remember the lockring has a left hand thread so turn clockwise to remove it.
