(TO ANSWER THE QUESTION OF STRENGTH OF FRAME MY FATHER PUSHED HIS ROAD RACING AND I PUSHED THEM 20 YEARS LATER) A GREAT FRAME TO EQUAL IF NOT PASS HETCHIN AND HOLDSWOTH WOULD CONDOR CYCLES BOTHER WITH THE MARK IF THIS WERE NOT THE CASE.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-18899086.post-71904604411401427162008-05-19T05:45:00.000-04:002008-05-19T05:45:00.000-04:00I have one and it's a beautiful, powerful ride, sp...I have one and it's a beautiful, powerful ride, speedy as you like despite wieghing a tonJakehttps://www.blogger.com/profile/14490548251643427200noreply@blogger.comtag:blogger.com,1999:blog-18899086.post-85732741440645135212008-05-10T03:34:00.000-04:002008-05-10T03:34:00.000-04:00Dave says:"a bicycle frame twists as it is being r...Dave says:<BR/><I>"a bicycle frame twists as it is being ridden, about a line from the head tube to the rear dropout.

Now imagine if that junction started rusting with time. Just my opinion :) but again, this material is steel so you could keep your fingers crossed.<BR/><BR/>I also wonder if there would be any added comfort vertically at the saddle because of the apparent 'disruption' in shock travel.<BR/><BR/>But its very interesting, I wish someone did an FEM analysis on this.
