I'm looking to replace my BMX with a 26" DJ/Street bike. I want to buy a frame only and build it up. I want sliding vert. or horizontal dropouts, disc mounts, 4" fork compatability, 1 1/8", and a MTB BB. I've been looking at both the Evil DOC and Specialized P. 3 frames. I'm leaning towards the DOC because of the sliding drop outs and the fact it's steel. Plus Evil has good customer service and I can pick one up for around 450 at Beyond Bikes. What do you guys think I should get? I'm open to suggestions. Also, I'm 5' 9", so I think I'll go for a small sized bike. Is that a good choice? Thanks for your help!
