Well, I took the new bike out this morning with my computer now working, and knowing how to change gears properally so I don't drop the chain and we rode 21 miles. I had an avg speed of 11.2 which is not any better than the mountain bike, but I think it is because the gears are bigger and I am having to muscle it a little more up the hills instead of spinning so fast. I don't know, I just know I love the bike and I don't care. I will get use to it and speed up once my legs build up to those gears.
