looking at a rigid 29 SS for my next rig, once i heal up from this broken neck thing. i'm considering Niner and Vassago (who isn't). a big issue for me will be simplicity and ease of upkeep. i've never had an EBB bike before, so i'd appreciate a bit on input on how fiddly they are. i've had horizontal DO frames, and the alignment can be a bit tricky, keeping the wheel straight and the disc brake aligned, particularly changing a tube or under the occasional heavy pedal torque. is one a distinct win over the other or are both equally fiddly?
