So this is the bike that I will be riding. It is a 2013 Giant Defy Composite 2 which I bought from Hollingsworths.
This is what Giant say about it: 2013 Giant Defy Composite carbon road bike is versatile with a longer wheelbase and slightly taller headtube for endurance positioning for a ightweight, smooth riding feel that makes the road disappear beneath you. Crafted from Giant’s Composite material, the all new Defy Composite features innovative technologies including PowerCore bottom bracket and OverDrive headtube for stiff pedalling efficiency and razor-sharp handling. RideSense-ready, for use with Giant’s wireless ANT+ data device.Featuring the same endurance geometry as Cycling Plus Bike of The Year Giant Defy Advanced.
