Hello Jaime,Tobias Gommel has built a python with really fat tires. See attached picture. I think that apart from such a 20" front wheel there is no other realistic solution for your inseam length.
On this page http://en.openbike.org/wiki/Pivot you will find a brief overview of steering pivot solutions. Ordinary steering heads have already been tried. A friend of mine has one and there is no sign of wear or play yet (1000 km), so I would give it a try.

Hello all Here I am again with a hand full of questions... After some days of "frying metal" (as someone said before) and reading some very interesting posts here on python's mailing list, I must say, but the things that raises me questions are much more than the others. Maybe Iraised the goals far above my skills, but I will not give up. So... one question, maybe someone tried it before (I did not have thetime to read all previous posts, so maybe someone did): As I need a "fat" front wheel tire, the "standard" python front wheel frame is a real problem I was not able to solve yet. Solution (?): building an arch over the front wheel from BB to center pivot, attached to the wheel hub with a triangular structure. Does it seem practical to you (inabstract)? Second question: In a previous post was discussed what is better for thepivot. As I don't have another BB to use here, I was planning to use a standard front wheel pivot from an old DF bike. Will it be a good choice? There are very strong forces involved in the center pivot so... I am not sure. Maybe someone can help me based on experience.
