Here’s a detailed breakdown of what you need to know to find the right casters.
The Most Important Factor: The Stem Type
Gaming chair casters almost universally use a standard stem size. For the Xtrike Me GC-905, you are looking for casters with a “G” type stem.
What it looks like: A round, plastic peg that is approximately 1.1 cm (11 mm) in diameter.
How to be 100% sure: The best way is to pull one of your existing casters out of the chair base. You will see the round hole it plugs into. Measure the inner diameter of that hole—it should be very close to 11mm.
The stem you need looks like this:
(It’s a universal “G” stem used by 95% of gaming chairs)
Key Considerations When Buying New Casters
Since you’re looking for a specific color (Red), you have a few options for the caster type:
Standard Hard Plastic Casters: These are the default wheels that come with most chairs. They work fine on hard surfaces but can scratch hardwood or laminate floors and are loud.
PU (Polyurethane) Rollerblade/Smoothie Casters: This is highly recommended.
Softer & Quieter: They roll much more smoothly and quietly.
Floor Protection: The soft material won’t scratch or mark hardwood, laminate, or tile floors.
Better Mobility: They often provide a smoother rolling experience on both carpet and hard floors.
