If you didnt plan on riding it in your city Id say get it.
Otherwise Id want a full susp with at least 5 inch travel front & rear.
Im doing about 60 a week now, slowly working my way back to 140.
Used to do a 20 mile round trip to college 5 days a week and 40 on weekends.
After I bought the KLX400 my mountain bike took a long break...
Still on my 6 yr old DBR full susp cross country, still pretty light.
Has front & rear lockouts for pavement or hills.
I would have a roadie too but I like the dirt so much more and live near
a great river with far to many opportunities to drop off the paved trail.
