Looking to replace the bearings on a set of 2008 HED Ardennes C2 wheels. Looking for stainless bearings. To this point, I have learned that I need the following:

2 X 6901 (front wheel)
3 X 6802 (rear wheel)
1 X 1526 (freewheel?)

Two questions:
1. What do the numbers for each of the above bearings mean/indicate?
2. How does one find and purchase such bearingsto get the best price on good bearings?

Thanks for any ideas and for your time and consideration.

The number is the 'bearing trade number', which is a mostly standardized designation that identifies bearings for their size.

Good place to procure them is Carr-McMaster.

Here's the page with your #6901:http://www.mcmaster.com/#ball-and-roller-bearings/=1z5swp

Look in your phone book under "Bearings". If you have a Grainger, McMaster-Carr or other specific bearing supplier in town, take the old bearings to them and get a match.

Be careful what you ask for since bearings come in a variety of ABEC grades from 1 to 9 and the higher number grades can be very costly and overkill for bicycle use. Typically ABEC Grade 5 is more than good enough.

I know someone who told the counter guy "give me the best you have" and was shocked at the cost.
