This is sad, don't even have my bike yet and went ahead and picked the bearings up today while at work. At least I'll have them....

I bought mine years ago from Bearing Resource, but I don't think they are selling online any more. Check the following thread.

I found NACHI brand Japanese bearings on Amazon, in the sizes you listed. They were about $7 each, as opposed to $1 - $3 for the other brands.

What is the size for the front wheel? I'll just make a go of it, and buy all 5 right now.

The front wheel employs two, 6302 2RS bearings.

5 bearings totaled $22! For piece of mind, sounds good to me!

If I recall correctly, bearings were the only issue with some guy riding through Europe, right?

I think the Silk Road Rider only had problems with his rear wheel, and I wouldn't be surprised if it was only the 6202 bearing causing the problem.

The 6302 bearings are large and robust. The 6004 bearing is serving light duty in the sprocket carrier. As long as these bearings are packed with sufficient grease, I don't think they will cause any problems. However, I received a replacement rear hub from CSC which only had two bearings. I suspect the Silk Road Rider had the same hub, and the weak spot is the single, 6202 bearing in the rear hub. RX3 bikes sold in North America have an upgraded rear hub which contains four bearings, instead of two.

In post 37 you posted the bearing # as 6203. Is one a typo?

Can the bearings be re-greased in place (without removing them from the wheel)?

I made a typographical error in post #39, and I have corrected it. Thanks for letting me know.

Except for the 6004 bearing, all the other bearing numbers end in 02, which indicates an inside diameter of 15 millimeters, the diameter of the axle.

The 6004 bearing of the sprocket carrier has an inside diameter of 20 millimeters, since it contains a bushing which has that outside diameter.

Give it a try; you might be able to do it. You have nothing to lose by trying.

Here is a photograph of the SKF 6202 2RS bearing I installed in the sprocket side of the rear hub. Since I have an earlier version of the rear hub, I only installed one of these bearings. The bearings in the brake rotor side of the hub are 6302 2RS bearing.

I used the orange pick to pry open the rubber seals from the inside diameter of the bearing. I packed the bearings with Lucas Red "N" Tacky #2 grease. The photo also shows my 15 mm split collet, and the large driver I used to drive the old bearings from the hub.

Here is a photograph of the worn original bearings I removed from the rear hub. The 6302 bearing on the left was missing one of the rubber seals. This bearing was locked and dry.

The 6202 bearing on the right was completely shattered. I needed to cut the outer race with my dremel tool in order to remove it from the hub.

Wow - those are some dramatic photos. Given that, spending $22 for a set of spare bearings for peace of mind is cheap insurance.
