Review on 🛠️ Acekit Bike Headset Cup and Bottom Bracket Press Installation Tool: Effortlessly Install BB30 and BB90 with Precision by Stephen Russian

Luckily I had a 3D printer. The supplied die sets have an inner diameter of 28 mm and an outer diameter of 50 mm with a depth of 9 mm. Some/most BB30 bearings have a 2.5-3mm insert, meaning the outer 50mm will not allow the bearing to be fully pressed in. I made a 3D printed adapter for 29.9mm (to provide some offset but actually center the bearing, if not you have up to 2mm of possible side loading and offset. Also I have a 41 OD, Made 9mm and made it higher to let it push and insert the bearing without a 50mm metal plate that sinks onto the bike After these mods it still worked very well It's a threaded road with washers, a nut and a knob that isn't that difficult to screw in. I wouldn't do it Assuming it's a tool for a BB30 mount, I'd look for something with an inside diameter of 30mm, an outside diameter of 42mm or less and enough Search for clearance to place the bearing fully in the seat.
