when should i buy new bearings? i've had modus titanium for a year now should i buy some new bearings?
Well if they still work, why are you gonna buy new ones? I wouldn't buy new ones unless they get caught, or I totally bust it out. But if you buy new ones you will definitely feel a difference. New bearings are smoother faster and overal more comfortable.
If you see they stop after 2sec then your bearings needs to be changed as soon as possible but if they are slower you should clean them up with gasoline or lubricant I think that good skate board bearings will last maybe 8 or 9 month if you take care of them properly means cleaning them at least every two weeks.
