Hey guys I currently have a zeb r fitted to my sam2 6.8, but after scratching the stanchions at the weekend I’m thinking good excuse for an upgrade, but when I’m looking there seems to be two standards for steerer tube fitment and I don’t know what I need. Do I need 1.8 tapered or 1.5 ??? Hoping some one can help, I’ll. e looking at putting another zeb on as replacement
