i would say the bradbury manitou is right up there with the most sought after frames.
it was the first production bike doug brabury designed and is a true classic.
right up there with any frame you care to mention.
as scant says, they crack because doug was trying to push the weight limit of the frames.
i brought mine without noticing the crack.
i brought it because it was a frame i had always wanted back in the day, but could never afford.
the best reason for buying a retro frame in my opinion.
you can tell the value of these frames on the open market today because i sold mine on, as a cracked frame, at nearly 3 times what it cost me.
if i could find an undamaged frame, i would buy it tomorrow, and hang it on my wall.
and that's saying something, as i'm not into garage queens
