Got an email from CompetitiveCyclist today and they have the 808s and 404s on sale. The 808 are firecrest tubular too.

What are the differences between the 2012's and the 2011's besides the rad beyond black colorway? The rim shape is obviously firecrest but i didnt see any other hub etc benefits.

New hub. It's not just the colors. The hub is new. Or, rather it is an "update" to the 88/188.

From Zipp.com:

88/188 – October 2011

Re-design (V7) and improve the current 88/188 hubs with canted, rear, non-drive flange and rear axle changed to accommodate 7.5mm wider non-drive bearing location. Hub are offered in two color options - falcon gray and beyond black across the wheel line, (October 2011).

These changes improve rear 188 hub axle durability and allow 6% stiffer wheels to be built with the same spoke tension. On the 88 front hub, the only change is the color options – the silver and ZedTech hub 88/188 hub versions are discontinued.

Note: the rear 188 hub shell and axle are NOT compatible with the earlier silver version. The bearings (61803) end caps and seals remain unchanged.

You can buy my 2010 808s so I can upgrade to FC. :p
