Huh, cannondale does actually still call them HollowGrams though
confusing of them
In that case, the Hollowgram name is basically branding rather than an indication that it's hollow.
Well, before the Si forged crank they all were hollow...
I reckon that's just a bug in teh internetz; the data sheets I've seen refer to the Si forged crank as Cannondale Si
Still a good product as it takes the same hardware as the Hollowgram cranks, spidey, OPI and whatnot. Great for MTBs.
