If I had unlimited budget to build a custom bike, I would want one that fit like Claire. I would have my builder start with her as a blueprint and then make her more pretty. A more graceful looped top tube or a swan frame. Prettier lugs.
Then I would steam punk that baby out. Cooper plate on the tubes, brass coated lugs. An reproduction antique front light that was secretly powered by a dynamo hub and LEDs. Brass plated fenders and chain guard with an ornate pattern cut out. Leather saddle and handle bar grips. I would want to find a way to put cream Fat Franks on it. I would want wicker panniers. I would have a bike that was beautiful to look at, but still had that wonderful ride quality that is so Claire.
And I would be afraid to ride it anywhere in case it got stolen.
But all that stuff is just appearances. I have no complaints about how Claire fits or rides or handles. At some point I may have to have her dismantled and sent away for professional powder coating, since the paint isn't as hardy. But that isn't going to change how she handles.
I really enjoy riding that bike and she is perfectly matched for riding with T.
The Nishiki on the other hand..... is fine. I only use about three of the speeds when it is just me, but when I have the toddler trailer or the panniers loaded, I need the extra ones. I just don't know enough about road bikes to know if I could do better. Or to use it to its full potential. None the less it fits comfortably and I feel like I can go fast on it.
Either way, I have bicycle contentment.
