hi retro guru - I did, its with steve potts and its staying original. The new seat post will be bigger diameter tube but it will look the same. Yeah it was the join between the seat tube and top tube but on the outside edge. After 18/19 of riding it 2 or 4 times a week including in rigid SS mode it failed. It was my mistress in life, my bit on the side, so i had to send it back for a fix.
As for the handjob, you need to get that sorted. You have to find a ti welder who you trust. I chose Potts as his work on my bowTi was frankly AWESOME ART. There isnt anybody here in the UK I would let near the ti mojo, no disrespect but I just wouldnt. So when it failed it had to go to California to be fixed. One word of warning with steve is that he is a busy man and you have to be patient. He's also more interested in welding ti than emails and communicating. But thats sort of the way you want it. If you send your bike to him expect a few months before he turns it around. For me thats a good job as it give me chance to save some money so that I can pay for the work!
