Chumba Racing VF2 / Lefty Build part 3

Today I am feeling a little like Dr. Frankenstein. The doctor, mind you, not his creation.

Bwaahhh hahhh haah ha...Its aLIVE!!!!


Well, sort of. I did install the lefty onto the frame using the adapter. Still a ways to go.

This is a closer look. You can see the upper crown of this Lefty is offset upwards. This is an option Cannondale only started to offer last year. The traditional layout is for the upper crown to look pretty much like the lower crown. The new upper crown option will allow the Lefty to fit many more frames than before. The limitation of the fork is that the head tube plus headset height must fit between the fixed spacing between the crowns.


I created this exploded view to show how it all goes together. In this case I had split the race (make a cut across it) to make assembly possible. It is hard to explain, but if the race has a bigger diameter than the adapter sleeves it must be split. Most races are either small enough or split anyway. But the Chris King race is an example of a race that is both too large and solid so I needed to modify it. It does not affect the performance of the headset.
