For BoXXer top crown sizing, if the head tube + headset is under 160mm, choose the short one with 3/4 inch drop. If it's between 160 - 190mm, go for the tall one with 2 inch drop. The model is for 2021+ ZEB, Debonair (27') 38mm, and it's a 1.5>1-1/8' alloy CSU assembly.

Using this CSU assembly is quite straightforward. First, make sure your bike model is 2021+ ZEB, Debonair (27') 38mm. When installing, pay attention to the steerer size. If it's tapered, it should match the 1.5>1-1/8 inch spec. Also, choose the right BoXXer top crown according to your head tube and headset size. For maintenance, regularly check for any signs of wear and tear. Clean it with a mild detergent and a soft cloth. Avoid using harsh chemicals as they may damage the alloy material. If you notice any problems, it's best to consult a professional bike mechanic.
