Hey whats up in MTN bike land. Well here goes. I have a old Balance XC Mtn bike that the frame is cracked. All the components are of XT and XTR fashion. I have been looking for a dirt jump frame so that i can join my friends at the local dirt jump site and just ride around town. I have a 04 Jamis Dakar that i love but thats for XC and i also have a Haro escape 8.1 that i bought for my girlfriend but that now has extra soft springs in it and doesent really work for my 6'1" 225 pound ass. I was wondering what size frame i should get and what size frame you guys are riding for dirt jumping? I also was wondering about the Mountain Cycles Rumble that i found online for relatively cheep. Are they good frames or are they junk? Well thanks in advance for the help.
