I am looking at the Hope and Wheels Mfg thread-together press-fit bottom brackets and am trying to figure out how the individual bearings can be replaced when they give out. Seeing as it's the weekend and I probably won't get an answer from the manufacturers, does anyone know if you have to remove the entire assembly from the bike to change the bearings?

Edit: Maybe question 1 should be: do these alleviate creaking press-fit bottom bracket problems?

Thanks!
