Hi, I´m going to change the bearings to my bike´s wheels, it currently has in the front wheel, the OEM bearing NSK-6004DU (single contact seal), but my question is: isn´t it better to replace them with DDU bearings (doble contact seals)? is there any particular reason for having only one seal?
Also, searching for a good replacement I also learned about SKF bearings with low-friction seals on both sides 6004-2RSL wich reduces seal friction up to 30%, a bit more expensive of course but...
Can someone enlighten me in this topic?
Thanks, and ride safe
