|Cartridge replacement for White Industry hubs||NC_Jim|

|My White Industry hubs have always seemed stiff. Feels like they never broke in (I have 2k miles on them). I'm thinking of replacing the cartridges. What kinds of cartridges are out there and what are the considerations?|

|How did you come to the conclusion they are "stiff?" If you swap wheels with another bike, does the problem follow the wheels? Have you had a good mechanic or wheelbuilder look at them? Did you buy them new? Did they come local, mail-order or directly from WI? How old are they? Are they the current LTA model, or some prior model? It this a problem with the front, rear, or both hubs? 2k miles is plenty for the initial tightness of cartridge bearings to have gone away.
If you disassemble the hubs, you should be able to spin each bearing and feel for binding. Maybe you just have one bad bearing, or maybe that's not the problem at all. A good bearing can bind if it is not installed squarely into its seat, so check they all look like they are evenly pressed in.
White uses Enduro bearings, which is ABI Industry's brand name for their bearings made specifically for the bicycle industry (http://www.abiindustries.com/Pages/enduro/index.html). Any bike shop can order them for you. However, if I understand you correctly, you are trying to upgrade from the stock bearings.
The bearing specs are on the White Industries web site at: http://www.whiteind.com/fronthub-chart.htm and http://www.whiteind.com/rearhub-chart.htm. There are seven total bearings in a set of WI hubs, two front and five rear. The bearing numbers (6901, 6902, & 6802) are industrial standard numbers. The suffix -2RS indicates that they have seals on both sides. So you could go to any industrial bearing supply house and ask for a 6901-2RS and they should be able to tell you what's available in that size. At that point, as always, price is indicative of relative quality, plus the salesperson should be able to recommend a quality bearing. - Dave
