I am sourcing a carbon frame from an offshore supplier, and wot they are selling me is an ISP (integrated seat post) frame. From wot I understand about ISP frames is that they are more rigid (which is wot I need in a TT bike). But this means seatpost is required to be cut to a height that fits me? They have sent me this drawing which doesn't make much sense to a n0ob I am.

How to cut the integrated seatpost to fit me? If I take it for a bike fit session, will they cut it for me? Is it too much hassle/risk?
