Hello Talk Composites,
I am a small scale bespoke frame builder, building frames from steel in Sheffield UK. I build using traditional methods, fillet brazing, silver brazed lugs etc etc. I use these traditional methods but always look for opportunities to build in technical and functional improvements in to the frames. Have a look at my web site for more of a picture
www.fieldcycles.com I am building a few frames with an integrated seat post like the images attached. I would like to replace the extended seat tube / seat post with a composite tube. My idea is to build a frame with a lug at the bottom bracket and the seat tube top tube junction and then bond in a carbon tube. Any advice would be greatly appreciated, things like clearances, bonding composites to steel would be really helpful.
Ideally I would like to use a composite tube that has an o.d of 28.6 mm (1 1/8") so it will work with the seat post top I make.
