Question about L33T Castors for gaming chairs

I think they fit. I've had these castors for quite a while and haven't had any problems yet, quite the opposite: they are quiet and leave no marks on the floor.

I don't know. We have attached them to gameing chairs, where they fit and roll very well and do not leave any marks on the oiled parquet floor.

Unless you weigh 25 kilos you should not buy single wheels, they quickly bend and make life hell... It is imperative to buy twin wheels... ...but be careful, in general they are smaller, be careful that the central axis of the chair does not touch the ground. Concerning the wheel axle, there are two different sizes: 9mm and another size, you have to check this parameter normally indicated in the wheel parameters. The most common size is 9mm...

I would only use Origanal castors, otherwise the static of the chair is not ensured.
