I have a truvativ touro track crank and Im gonna replace it. I would like not to have to replace the bottom bracket if I dont have to. It has the square taper bottom bracket but I can not find out if it has a ISO or JIS taper. anyone know? I cant find anything online or when I call truvativ. Thanks

This is just an educated guess based on information from Sheldon Brown but unless the crank has "NJS" stamped on it somewhere, it's going to be a JIS taper. I'm basing this guess on information from here: http://www.sheldonbrown.com/bbtaper.html
