I'm new to the dh scene and am looking to build a bike. I'm 5'10" and seen that a med frame would fit but what about a large? Would it be oversized? Also I am going to be doing mostly urban riding (stairs, curbs and some dh) and am looking to get a full susp bike. Would like a stiff ride. Any suggestions on shock/spings/fork setup? Since I am new any info would be great. In the mean time I'll keep reading through the forums. Thanks
