No issues with the BB height and size of frame, to me it rides like how an XC bike should feel. I'm 6' riding a large, with a 120mm fork, 50mm stem and 780mm handlebar. All said, it is longer (and slacker) than my old hardtail (that had a 71degree HTA), so it is not as agile on some the twistier trail sections, but I can ride it more aggressively on the downhills. I guess that's the trade off with today's bike geometry. I purchased the RS Monarch RL shock with the frame, so I can't help with the bolts.
