I am looking at building up a street specific frame or getting a street complete (riot, mob, night train, atomlab, top, etc) and want to know if it will just feel way too unstable due to the short rear end and small feeling frame for occaisional trail riding? I would be standing up and pedaling with the bike as a SS, (which I already do with my Chameleon, which is SS) so seat post extenstion will not be an issue. This is not going to be a primary trail bike, but sometimes I won't feel like dragging my 39lb bottlerocket around. I will likely be running a Pike as well and will be replacing the Chameleon.
