Can anyone confirm the sizes of the rear wheel bearings on the 3LN(3)????? The writing is so small I can't make out if it's a NSK 5202Z or a 6202Z bearing, must be getting old <!-- s:-? --><img src="{SMILIES_PATH}/icon_Eyecrazy.gif" alt=":-?" title="Eye Crazy" /><!-- s:-? --> Changing the rear tyre for a 140/70 BT090 Pro today and the bearings don't feel smooth.
