New Source for Bike Parts

I have waited three months for my popular bikes source (Nashbar, BikeTiresDirect, and Performance) to get Hyperglide+ chains (CN-M7100-12). Finally, my son found an alternative source, Bicycle World. In early January, we have purchased eight of these hyperglide chains for the same best price that others were selling (if they ever receive them).

I think I just found my favorite source for bike parts. 

SIDEBAR: Doug has used CN-HG601-11 chains for his VADO 5.0 SL with 12-speed Ultregra. Almost everyone suggests they should work, but he has found the chain tends to hang up on the small cassette gears. We are guessing the 11-speed chains are a bit thicker than the 12-speed chains.

He also warns "Make sure your chain breakers are compatible for 12-speed chains." Those suitable for 5 to 11 speed chains might have a drive pin with too great diameter. It will crush a 12-speed chain.
