Yeah I'd have to agree with option 1- Maybe I missed it somewhere- are you planing on only making the one size? 28.7 for steel tubes? or also the 31.8 for aluminum?
29.8 or 30mm please decide before you do this (maybe ask for a sample base of measurements from peoples frames first) Tolerance is important. Also the step in the first design will clamp the seatpost. Why do we need a step?@NigelFinnighan 28.7 is for steel? Mine is around 30. I would say 29.8-30mm. Coul yi confirm. I will double check with my Altitude 1995 ST but I measured around 29.8 last week. I only plan steel at the moment, but o can see also 31,8mm if there is demand. Simikar prices around 20 $.
