So I tryed agressive inlines skates for the first time a couple days ago and idk but it doesnt grind .and yes i did go really fast to try to grind the rail . it was only a flat rail but i saw that the rail was larger than the place to grind whit the roller idk if thats why. and it really stuck and i tryed it like 30 times and doesnt grind really . i did wax the rail and my roller. it was a rain day so maybe it because of the water on the rail and the roller ? idk is it beacause the rail is too large ?
those are my roller exacly :
thanks for helping and +k
