I do a 4 mile urban commute with option of a crushed stone shortcut. I like to explore and sometimes end up on dirt roads, stream crossings, railroad beds etc. I have done this for years on a cheap steel mtnbike but I just got tired of being passed on the way to work by people on skinny tired road bikes. A jerk at the LBS talked me into a hybrid-big mistake: two days in the hospital and a separated shoulder. I love the stability and riding position of a mtn bike frame. I have been test riding a Cannondale Bad Boy. It feels FANTASTIC. Wonderfully stiff, amazingly light, totally in control on the pavement, and really fast. But I am wondering about the 28 mm tires. Am I kidding myself that I can take this thing off the asphault? I do not plan to switch wheels and I think 37 mm is as fat as you can get on that frame. Can I have it both ways? Is there a bike that will do it all? Is it the Bad Boy?
Thanks for the advice. JF
