ok, so i can remove the bolt that is supposed to hold the cranks together and they are still stuck together... im not a weak person and i pulled as hard as i could, i tried to wiggle them apaprt, i even tried preying them off... and they just arent even moving. is there some sort of tool or anything that is made for doing this? BTW the cranks are made by colonial, they arent the V2 series.. but its the same design... please help if you know anything about these cranks.. thanks =)
