This was my first thought too. Cable housing sizes are standardized enough that I would be really surprised if they somehow 'got it wrong' with the ferrule stop in the frame.

A friend of mine picked up a Ridley Cheetah TT frame and did the same thing: Measured and cut his housing, lined it all up and then started installing...realizing very quickly that it was designed for full housing.


*Edit* Also, if the cable dropped in and you don't think it's designed for full housing, HOW IS IT FUNCTIONAL? Cable housing needs to be either continuous or stopped securely on something in order for cable length to be fixed and shifting to work properly. You say in the OP that it's probably not a big deal...but because of the above reason, how is it not a big deal?
