Most Aerodynamic TT bike In Tour History?

Since 2001, over 90,000 cyclist's have joined Cycling Forums to discuss topics from general cycling to equipment, training, racing and travel or vacation destinations (especially in europe during the tour de france). We also feature an great deals in our online store, 100's of articles, classifieds and product reviews.

I was just watching a DVD of the 1998 Tour De France and Jan Ullrich's highly unusual TT bike with the back wheel being very large and the front wheel being very small. Chris Boardman also had a strange looking bike. Of course Big Mid used to ridhe the single piece frames in his Tour days. So which bikes are faster, those of the mid-late 90's are the ones of today?

to me the one indurain is using there actually looks like a POS compared to current tt bikes. it there is to much airflow to the back wheel.

i heard the design that ulle rode in the '03 tour was quite awesome. it was narrower at the BB and he obviously used it to great effect in that tour. in lance armstrong's war there's a bit about it and how trek stole the design and lance was getting great times with it, but they scrapped it because he was getting poor wattage.

Too much air hitting indurain's back wheel.

what about this? http://www.cbdcycles.com.au/images/cervelo05/cervelo05p3carbonfull.jpg

Indurain, the cervelo, the indurain bike or all 3?

I wouldn't pass up any of em:p

I'm pretty sure the models that Indurain and Boardman used are now illegal.

I'm pretty sure the models that Indurain and Boardman used are now illegal.if that's the case i would bet it has to do with geometry and not aerodynamics.

Not double triange=UCI illegal.

not anywhere near as aero as a tour TT but here is an old school big wheel/small wheel example. my friends fixed nishiki. hope the link works.
