I have a 2004 Gary Fisher dual sport 229 MTB ( 29 ‘ wheel) which I use it primarily to commute to work, about 42 miles round trip ,which includes 9 miles total off road ride and the rest is bike trail and roads. I am fine with my bike, but it’s slow especially on the roads and hills . Recently in my LBS I saw a 2004 Bianchi Axis cyclocross bike for 779 $ around 470 $ off the original price. Since I ‘ve never had a cyclcross bike, I was wondering if you can tell me that It would be a good replacement of my MTB, or in reality it won’t be too much differences. Thank you for your help.
