Evolution of a time trial position

Rob Aero Tips, Equipment

I came back to Time Trialling around 2009 using my Trek Madone road bike. I was slower than I was when I was 16. I started to look at way to get faster without spending too much money. That worked up to a point but I soon got bitten by the bug and started to “invest” …

Options for the front end
