Hey guys, I've been looking really hard at buying a new frame and have looked at just about everything. Recently sold an Ellsworth epi frame and am thinking I would like to get a 575 again, had the old model and loved it, but that was a few years back. I see 2010 comes with either a full carbon or carbon/ alloy rear triangle, does anyone know the frame prices for these or specifically the difference between the two. Also are the frames already available for purchase, I know when I bought my old one I had to wait a bit into the new year before they were ready. I looked at Jenson and believe they had the 10' full carbon rear for $1800, but to be honest Im probably more interested in the carbon alloy combo. Any info would be helpful, lookin to buy within next few days, if I can research it enough, thanks.
