I happened to be at my LBS the other day when the Cannondale Rep was showing off the new 2010 Super Six. Among other things, he said that the 2010 Standard Mod was equivalent to the 2009 Hi-Mod. So evidently they are doing something to make the Hi-mod more Hi-mod.
I'm looking forward to the day when the new model comes out and the engineers/reps have nothing to say about it because last years model was an invisible carbon nanotube. Seriously, these jumps in weight loss and stiffness have to slow down at some point?
So is there any difference between a 2010 Hi-Mod Ultimate and a standard 2010 Hi-Mod frame?
From the Cannondale website (and from Starnut's postings on another thread), it looks like there are two Super Six frames. There's the Super Six High Mod that comes with the nude finish as the ultimate or with various paint jobs in the Team and High Mod 1. Then there's the "regular" Super Six (not high mod). The "Super Six High Mod" 2 and 3 are actually kind of deceptively named because they come with the regular Super Six frameset (not high mod frame) - at least that's what I gather from the specs on the website. As others have posted, I think the difference is primarily weight, with the "regular" Super Six weighing ~150g more.
That is what I was also told from my local rep also. But I'll have to take a look at the dealer book again because I'm positive they aren't calling the lower level SuperSix's "HiMod." I will double check the dealer book tomorrow when I get to work.
As for why they list HiMod for all SuperSix's on their website is mind boggling to me. If you look at the SuperSix 2 and 3 they remove the HM off the fork to show it is not HiMod though. I think the HiMod on 2 and 3 may just be a typo on the site.
Weigh does come in to play between the HiMod and the Non HiMod models. It should be about 100-150 grams less on the HiMods.
