Question about old school TT frames ...(6 posts)

Question about old school TT frames ...853
Jul 22, 2002 12:42 PM
I am planning on getting one brand new for very cheap(late 80's maybe early 90's Daccordi) I want to know why these came w/ a 650cc front wheel and now all TT bikes don't? Is it not as aero or is it illegal to race these? and why? I'm just looking for some info regarding these and why everybody has gone back to 700's.

I have a 700c tt bike. I compared, but considered this:

1. The wheels and tires are interchangeable with my other bikes. I'm using my Zipp 404 front wheel on my Colnago this weekend.

2. In larger sizes, there is little, if any, aero drag reduction, because the head tube gets taller. Take a look at the technical articles on the Cervelo web site. However, in the smaller sized bikes, the 650 wheels allow a lower handlebar height.

3. Larger wheels are more stable and roll better.

4. Gearing is easier to fit, and again interchangeable with regular road bikes.

Reason 1 mostly did it for me, though.

go for it ...its a nice frame...Spirito

daccordi have made some real nice stuff and were a well regarded maker in their day.

if its one of the one's pictured below i would go for it if it fits. that style of bike is not common and will only appreciate as its a little too soon to be valued by collectors. they look fantastic too. ive always wanted a pinarello prologo in a similar style in a grey camoflage paint - very 80's.

below is a link to one of their earlier catalogue's and has a brief on their TT frames but they are in a straight tube style.

buy it build it up and be proud - if it has chrome then even better. i know for fact that you would probably make money offering it to bike courier's as they would drool all over its lines and style.
