i have a set of first gen peregrine cranks that came off my haro team master bitd, there's a bit of play in one of the arms and i'm not sure if it's a worn axle or worn arm or both. i dont know wether to keep them incase i ever want to do a haro build or just sell them. any idea how much they may be worth or if someone has a spair axle for sale to see if that fixes the problem with them.
