OK, so after a lot of research on here, I've decided I want to get some froglegs softroll casters. I've checked and double checked the fork width, height, and footrest and other clearances and am satisifed about all that. The only thing left for me to worry over is the bearings.

My chair is a Zra one, with 4x1 Tisport softroll 2 piece billet casters. I'd seen something on here about the bearing size on Ti casters being different, so I wanted to know if the caster axles on my chair would acommodate a Frogleg's caster and bearing size. I'm hoping somebody here will be able to explain the deal with the bearing sizes.
