For this test ride, you need to concentrate on the difference in frame feel and flexibility of the 2 Seven frames (one Ti, one steel). The fit will be customized later if you buy a Seven, so try not to dwell on how well one or the other frame fits you. Likewise the components will be customized for you, so try to ignore differences in components as you test ride. I used to test ride about a dozen bikes a day when I worked in a shop, so know how to ride for maximum stress on the machine (these were test rides after repair, to make sure the bike wouldn't break for the customer).
Drivetrain stiffness: The best way to test drivetrain stiffness is to pound as hard as you can up a hill in a gear as big as you can manage. This will flex the frame (mainly the chainstays) to its max (or to your max - a larger stronger person could flex it more). Do you feel like all of your power is going into forward propulsion? Does it feel snappy, like it responds immediately to pedal power? Part of the stiffness you feel will include any flex in the cranks as well, but most crankset these days are adequately stiff. (With old steel cranksets of the 70s, you could see them bend when you mashed the pedals hard.) Go up the hill as hard as you can and again with whatever gear/cadence would be normal for you. Generally stiffer is better here, but it needs to be balanced with the comfort of the overall ride.
Frame comfort: Here's the bumpy road test. Ride the bumps sitting, on hoods and on drops, and standing. Does it soak up the road shocks or transmit them directly to your hands, feet, and butt? Can you pedal over the bumps with minimal interference in your pedal stroke? Does road comfort come at the expense of drivetrain stiffness? Part of the shock absorption here comes from the wheelset, so try to ride both bikes with similar wheels if you can.
Descending: The bike should feel stable, you should be able to transfer weight to the front wheel, and the steering should be responsive - quick but not twitchy. Find out if the head angle, fork rake, and trail differ in the 2 bikes you test. That should affect the steering feel and then you'll have an idea of the geometry you want in your custom.
Remember that Seven will customize not just the frame angles, but the tubing, so they can dial in the stiffness and flex that you want for either a Ti or steel frame to some extent. Let us know how much difference you can feel.
Oil is good, grease is better.
