My Fuji Pro had similar characteristics - minus the speed wobbles - and I loved it. It was just perfect under me leading a race down Smugglers Notch in the rain. Another possible factor for the TiCycles is that the builder used a lightish tube for the top tube; knowing the bike was plenty stiff for this rider (we'd ridden together). I talked to the builder about it a year ago and he said that we'd done just about everything wrong in the design of that bike!

When I got the bike at my age of 55, speed wobble simply didn't happen and I had no clue it could be there. On one of its first rides I did a local, very steep and fast descent with a very strong quartering tailwind. One of my fastest rides ever. Now I'm in my 70s, no longer have either the old strength or confidence and over 40 gets seriously scary. Same hills only other bikes are no issue at all.

I'm debating what to do. I love that bike. It is my all day, any road bike. Not especially light but it fits and feels so good it climbs like an angel. To have to ride the brakes coming home from the places that bike loves to go simply sucks.
