Precision bearings & replacement.
Anyone know front wheel bearing size.
Ceramic bearings for a 2014SR, with success reported for at least as long as the original bearings. The author is going back to steel.
Per Terry Hershner
The 2012-2014 wheel bearings are 6904 bearings which are bicycle sized bearings.
They lasted me about 20,000 miles per set.
Best is to use a 2015 wheel on the 2014 which will work but requires modification of the spacers.
I did it on my 2012. It now has 2015 wheels.
