I remember seeing a pic of Steve Bauer with Rockshox fitted for Paris Roubaix and the bike also had a VERY slack seat tube angle so the rider was almost sitting behind the rear hub. It looked really weird - or is my memory playing tricks on me?
I remember it also - really slack seat angles like a butchers' bike. Looked hideous!
It was something like a 60' seat and head angle and he was almost pedalling forward (if you see what I mean). The lower part of his leg was vertical when the cranks were parallel to the ground. This meant he was sitting a lot lower than most of the other riders and I can't imagine that controlling it was very easy, especially in Paris-Roubaix.
I'm sure the article about it was in Cycle Sport or Pro Cycling or one of the other 'glossies'.
Today is the yesterday of tomorrow.
