For the non-pro Denali (the cheap yellow one with the Shimano Revoshift):
The rear spacing is 135mm, but fork and stays are drilled for nutted / non-recessed calipers. For a bike that weighs close to 30 pounds (maybe a bit more) those single pivot calipers are somewhat weak, Not to mention the calipers are non-quick release and even if they were there's NO WAY you're going to get the (default) 700x32c tires off if fully inflated.
Fork weights 1022 grams.
Bottom bracket spindle is a bit wider than necessary. Had a hell of a time swapping in ST-2303 brifters.
Bottom bracket cable guide screw is too long to slide in a cartridge BB.
The stock headset could not be kept tight.
7 speed freewheel, not cassette.
