January 22, 2019 at 2:14 am #5297 tomatoadminKeymaster The non-Factory hardtails from ’96 until the 2001. The 2000-2001 base Homegrown falls in there but was a bit of an oddball.

January 24, 2019 at 1:06 pm #5313 tomatoadminKeymaster Yes, though the increased weight was also a function of the different aluminum alloy/tube butting, head tube-down tube gusset that wasn’t on the Factory frames, etc. The 2000-2001 frames with extruded bridge were advertised as sub-3 pounds.
