Ok so here’s the issue, I have an unknown brand frame, could be a nimbus 2, ramico or a yuni. I have no idea. Currently I’m running a 24 x 2.30 k Rad tire and would like to run a 24 x 2.50 hookworm. However I’m not to sure if it will fit frame “X”. The frame has 3 & 1/8inch gap inside to inside the fork blades and 3/4 inch gap between the current tire and bottom of the seat post. Is there anyway I can check to make sure it fits or is this a situation where I’m just going to have to try and see for my self. Any help and insight is appreciated.
