Large, double-sealed bearings keep on running for a long period of time in your RAAW. But the day will come when replacement of bearings is needed. Removal of the old bearings can be done through cutouts behind the outer race of the bearings with a hammer and a punch. The assembly of fresh bearings is made very easy with this tool.
The Jibb / Madonna V1-V2.2 / Yalla tool is designed for 28 and 52 mm bearings.
The Madonna V3 tool is designed for 28, 32 and 47mm bearings.
