Hi all, quick question for you. Can I interchange other brand steering tubes on my marzocchi z4 forks? My friend has an uncut 1 1/8 steer tube (above) but doesn't remember what brand it is although he doesn't think it's a marzocchi. It looks like it would work, appears very similar to what I have but I thought I would ask here to get some feedback. Lastly, the one I currently have is aluminum and this new one is steel if that matters. Any help is greatly appreciated. Thanks.
