In the event of someone remain interested, today I've done a very pleasant ride of 31 miles (50 km.) including 2.465 feet total ascent (750 mts.), averaging 15,3 miles/hour (24,5 km/h). The bike, as shows in the pictures, has a weight of 20 pounds (9 kilos).

It's wonderful the comfort in the shifting. It's only: steeper, one touch up, less steep, one touch down. I can forget at last the two cogs up or down shifting the chainrings. With this setup, 46 front, 36-12 rear, for me (almost half the value than a pro, climbing), I can climb a 9% grade without problems, so I'll change now to 34-11, and in a future, will shift to 10 speed, 36-11. Even with 46-12, the coasting is not so excessive as I was afraid of.

The bike, as you can see, it's not very pretty, actually some ugly, but I ride looking ahead, I don't see it riding and I ride alone, so I really don't mind at all, as long as she does what I ask her. Cheers.

Sorry I can't post pictures, as it seems. And a second edition because the pictures were too big, I've updated the links.
