My dad has just discovered strava and is looking for a way to get faster. He's thinking about dropping around £650, possibly more, on a carbon road bike which must be "light and fast".
He's 5 10 so I guess he'll need a medium and has size 11 feet (He's also after some road shoes and pedals).
It doesn't really matter too much how it looks cosmetically as he'll treat it like shit anyway. Mechanically it would need to be half decent but I could probably be able to fix minor problems.
28s would probably be best as he's a bit of a unit.
