I currently ride a lot of XC and AM with family and friends. However my true calling seems to be DH. I am looking at purchasing a DH bike and am still doing my research on which bike I would like to buy. Most likely the bike I chose will have to serve as a multi-purpose bike at times (rides with wife and XC type stuff). I guess I should just get to the point here. Are DH bikes much more difficult to get up hills? Will I still be able to ride XC and AM and keep up?
