Respuesta de SkatePro: Hi Finbar,
Sorry to hear that you have had some issues with the trucks.
Without some pictures, it's pretty hard to judge what is causing this issue as you are describing. Out of experience, I have the feeling that you need some stronger trucks to match the level of your skating.
We would like to check it out if there was something wrong with these trucks if you would like to. Just get in touch with some pictures and we will 😊 /Justin
