Hello this is my first post here.
First of all sorry about my english, it isn't very good. I'm from Spain.

I built a carbon fiber frame last year. I read the Brano Meres "How I built my carbon frame in my garage" and decidet to try, I tought that was more easy than welding.

This is all the process (in spanish, i'm sorry, but there are a lot of pictures.)

Como construyo mi bicicleta de carbono.

Now I'm thinking to build a track frame.

First I will mold a foam core, in two parts; front triangle and rear triangle including bottonbracket. There are a lot of things that I donīt know but I wil try to do it better than the first time.

My first question is about the drop outs. Do you think is better to build in carbon fiber or in alumminium or similar and joint with the frame?

I have a lot of questions and I donīt found information about this in any place.
I agree your help and if I can help please, ask me.

Thank you.
