So i got my new GT Power Series 20" about a month ago and it is pretty much all i have been riding. I have been doing sprints on it and riding it on the street as well as the track. I have noticed a huge difference at the track. I can now hit the more difficult lines much more smooth than i could on a mountain bike. My ability to manual has also gotten much better. Even on the mountain bike i am much more smooth and fast than i was.Another advantage to riding the twenty is the increase in competition at the local indoor races. I would be luckey to get 1 moto with four guys in the cruiser class, but on the 20 all my motos had full gates. I was just wondering how many othr monkeys out there train on a 20" either during the season or in the winter months?
