This frame is for a 5'3" rider who is very light. I didn't weigh the frame but it is well under 4 lbs. and should be a nice ride for someone at that weight.
The tubing is a mixture of True Temper OX, S-3 and Columbus 'Life'. There are a couple of Dedaccai tubes as well......pretty much the kitchen sink. I like blending tubing based on wall thickness and profile rather than brand name.
