To find the correct cover for your Castro fender look towards the top of the fender and you will be able to see the measurements. Then locate the required size from our chart and you’re good to go. Alternatively, locate the fenders original packaging and look for the fender code, then once again find the code that matches your fender on our chart, it’s as simple as that.
If you are unable to complete any of the above then you will have to manually measure your fender as shown in the above diagram.
