Bruce Gordon has done it on some show bikes..

....and all without the stigma of low cost.

Here's an enjoyable Bruce Gordon interview from the San Diego show. He talks about the lugged ti bike in the second half of the video.

IIRC to braze titanium you need a really big place full of inert gas and the metal heated up to whatev temp for brazing.

Sounds like its like brazing with a scuba suit on in a diving bell next to an underwater volcano.

(someone correct me if I'm wrong).

Aren't BG's put together using some sort've adhesive?

Yes, he mentions that in the video that I posted above.

I suspect adhesive ...

My best guess ...

Incidentally, this might be the secret ingredient in he Ottrots

That and a lil bit of love from ma'

That Harry Havnoonian is a sweet looking bike. A poster on the thread about the bike said it didn't flex nearly as much as conventionally welded Ti frames. Interesting. Could there be that much difference in stiffness between lugged and welded with Ti frames?

Early Merlins had a BB sway to them but were light and subtle. Yeah here is where my Serotta Bias comes out.... I have never been ona Serotta Ti that I found to "sway: to my disliking. Folks like Paule and Aneida Ride and big guys and I have never heard them talk about the lack of stiffness in the ti frame.

Serotta can build them as stiff as needed. In my "unbiased" view :) lugging is 99.99% of the time for looks in regard to Ti :D


The experts out there know far more about this than I, but based on the folks that I know who have raced ti, and who have been doing it for years, it comes down to the builder using the right geo and tubes for the client's requirements.

Hey Pete, You might want to inform you son-in-law that the only connection between St. Louis and Kirk World Headquarters is the Missouri River. And the current runs in the wrong direction. :) I suppose if Lewis and Clark could do it long ago, your S-I-L. SHOULD be able to get the Kirk upstream for an inspection by its creator. Triathlete :rolleyes: is he?

I'm not too informed on frame stiffness. I like a bike that handles and rides well. I don't like a bike that lets the chain rub the front derailleur when you stand and climb, even with the trim properly adjusted. Neither my Legend or CSI have that problem. Before I bought my first Serotta, I test rode a Concours that was like a size 55 with the seat post jacked up - I ride a 60. That Concours had front derailleur chain rub, but it wasn't meant for me.

Pete, don't you have a Legend you wanted to sell? That would be a good candidate for long-term loan to your son-in-law. I know you'll be out there often to see your grandson, but the Kirk..................., that seems well, too much to loan. If the Legend is gone, there must be something else in your basement that would be a good candidate.

Back in the late 1980s/early 1990s, Miyata made some ugly bikes with ti bonded into aluminum lugs.

and it looks like it now has taken up residence and has a mailing addrerss in St Louis. :)

But I will not make that error in judgement that I did on the OTTROTT!!!!

I will leave him with the CDA and then take him out to see DAVE for his own... I sure my daughter will say "sure it is in the budget honey? :D
