Had an awesome time watching Alex Dowsett's excellent showing at todays world hour record attempt.
First off some stats about the bike:
He had a total of four frames made and had them all built ready so he had threee spares on the day.
During his post effort interview he was answering a question about how far he could go he gave aways a couple of interesting snippets. He was saying that he wasn't sure of how he would do as as the developement of the bike was evolving he was getting faster.
One of the developements to his custom he didn't name but eluded to:
Some of the modifications will only last a hour
This interesting comment got me thinking, what kind of tweak would only be temporary? I immediately was thinking that it may be some kind of spray on / liquid based enhancement? I'll have to look into this one further...
