What cones to buy?
 

The cones on the rear wheel of my 2011 Rockhopper are both pitted. According to Sheldon Brown's tips, I need new cones and bearings. I pray the cups are OK. I know I need 18 quarter inch ball bearings - 9 per side. But what cones do I buy? These will be replacements for the stock parts.
Thanks in advance.

Yep, pitted cones should be replaced.
When I last needed cones for a generic Taiwanese front hub, I was able to figure out what I needed using the Wheels cone charts. http://wheelsmfg.com/tech/PDF/wheels_cone_chart.pdf

I didn't see mine on that chart. Would it be easier to just get a new axle assembly? Mine is 145mm long. Do they sell assemblies that include an axle, locknuts, washer, rubber seals and cones? If so, any idea which one I would need? This would be for a stock, 2011, 26" Rockhopper.
Thanks

I'd like to know this information if you find it out as I have a 2009 Rockhopper with Specialized hubs

Why are you looking to replace these? your bike is a 2011 model, and should have a years warranty, even with normal wear, cones should last more than a year.

Would be taking back to the LBS and getting them to replace under warranty.

Whole 'nother can of worms. LBS sucks. Specialized service/warranty sucks. Have had numerous problems with this bike. Bike mechanic at LBS told me "I felt some roughness in your rear wheel when I had it on the stand. You should fix that." At one point I got a hold of the area warranty rep, but he had talked to the LBS first. I don't know what they told him but all I got out of the rep was to take it back to the LBS. The LBS has had this bike back 5-10 times and all they do is F it up.
Sorry for the rant but I have sunk the original cost of the bike plus the cost of replacement parts, and my time and travel in efforts to get it fixed. I've been stranded by this bike several times. I don't have time to take this through small claims court or I would. I've resorted to trying to fix it myself.
