ZTTO Bicycle Hub Titanium Steel Star Ratchet 18T 36T 54T 60T Ring Upgrade Kit Teeth High Engagement MTB Road Bike Gear 350 240

I used ztto ones that are hollowed out and they fit RD13 hub which is what you probably have in your edge wheelset. I used same ratchets on my yuanan(elite), xmcs and tagoola wheels which also have cross compatible freehubs. I don't think hollow/solid ratched matters as long as you use the provided springs. Make sure you are buying ratchet with 2 springs since a newer dt swiss design (ratchet exp) has only one with the other ratchet screwed into the hub shell
