Rollers on my speedfight 2?

3 gram is very light and may well lower the top end as the variator will not have enough weight in it to pull the belt right into the rear pulley best thing to do is try it you can always mix and match the rollers 3x 3 gram and 3x of the ones you have in it now(whatever they are)?
