Building up a Waterford frame, advice wanted
I'm getting ready to purchase a custom frame from Waterford and I have a question about frame materials. First of all, the bike is going to be used as mostly as an ultimate commuter, but also for many long rides and some touring. I sold my car and I'm sinking the money into a nice commuter bike. I spend a lot of time on my bike each day, and I want to spare no expense to get something that I love.
The person at my LBS who is helping me with the design also has a custom Waterford. What originally drew me to them is their unique disc brake mount, on the inside of the triangle along the rear chain stay.
The characteristics that I'm looking for is something stiff and sturdy but also lively -- something that's fun to dodge around in traffic. I realize that there are compromises to be made here, especially when I'm talking about the ability to put racks & panniers on the front wheel for an occasional tour. And here, finally, comes the question about frame materials.
I'm really partial to a beautiful Waterford steel lugged frame made out of their typical OS frameset. I'm worried that this will be too heavy and not so lively after all of my other riding parameters are met. What are the benefits/drawbacks of a TIG welded OS2 frameset? My buddy at the LBS seems to like the livelier feel of larger tubes. Is there a significant difference in weight and riding characteristics between larger thin walled TIG welded tubes and narrower gauge lugged frames?
