Cannondale Bicycle Corp. – Si Hollowgram Cranks. My buddy dave has these proprietary cranks on his Cannondale. They are nice but as with all proprietary designs, you can’t interchange them. Now he wants a Campagnolo Record CT crankset for our middle-aged legs, so the question is how do you get the darn things off. What tools do you need.
Also, I presume that the frame itself is English internally so you can just put the Record cranks and bottom bracket on, but it isn’t clear to me.
They have “manual”: for the Si Hollowgram and it makes it seem very hard to remove and replace the bottom bracket. Requires a host of special tools. Arrgh. I hate proprietary stuff!
Seems like someone at a shop needs to do this. Well beyond me as I read it.
