I am new to the cycling world and I have been doing research for the last 2 weeks on what bike I should get. I was looking at Marin, Novara and now I am really looking into Kona. I am looking for a bike that I can use as a commuter bike but also something I can use on the light trails that go through Red Rock National Park out here in Vegas and I am also looking to eventually start into cyclocross. A lot of people have told me that I should get more then one bike then and I am thinking there is no reason to get more then one bike. I was thinking if I could find a good cyclocross bike that would cover my trail riding and they are pretty light so it will not be a bad commuting bike. I will be going about 100-150 miles a work week. I was thinking that I could get different tires for when I am just commuting and going to the store and others for when I am going to be going on trails. Let me know what you think. I have been looking at the Kona Jake mostly.
Oh I will also like to be able to have a real rack if possible if not a messenger bag will work.
