Hey, man! Thanks for commenting on my blog today! I read your about finding a passion - something for yourself: and then I saw the status about your morning walks and how good it feels....call me crazy, but maybe your passion is right in front of your eyes! Maybe a couch to 5k challenge is in your future?!?! Just a thought. 420 days ago
Thanks for you comment on my "Pedaling a Bulldozer - Fat Bike" Blog. My 9:Zero:7 suits my riding style and is really a mountain bike with a rigid frame and high flotation tires. I demoed several brands and styles of fat bikes before I bought the 9:Zero:7.
Compared to other mountain bikes the fat bikes provide better traction since the low-pressure tires conform to the surfaces better. My fat bike can rail any corner whether the surface is hard pack, mud, sand, loose-over-hard, ice or snow.
All this traction makes the fat bikes harder to pedal. Rolling resistance it pretty high. Fat bikes are also very stable at extremely slow speeds so tight switchbacks are a breeze.
My 9:Zero:7 is just over 29 pounds, which is quite light for a bike with such huge tires and wide wheels. I used the 9:Zero:7 this summer when we had torrential rains that turned trails into mud bogs and meadows into swamps.
I ran 10 psi in my tires which made the bike a little bouncy going over roots and rocks. I could have run a lot lower pressure but then the bike would have been a lot harder to pedal.
The 9:Zero:7 is quite compact and extremely responsive. Most fat bikes are longer, more stable and less responsive than the 9:Zero:7.
There is a trend now toward full-suspension fat bikes, which allow the bikes to do better in dry and rough conditions but add weight and take away from pedaling efficiency.
The 9:Zero:7 has been used to win a lot of professional snow races. The Fatback is a very similar bike to the 9:Zero:7.
The fat bikes from Surly and Salsa are more stable "touring" style bikes. I have not been on the Specialized Fatboy or the Trek Farley so I don't know how these bikes ride.
