After teasing it to the world at the recent Tour de France, Giant has today announced the launch of its new Propel aero road bike. The launch sees a marked shift in focus for the bike, as Giant claims the top-tier Propel Advanced SL 0 tips the scales bang on the UCI-appeasing 6.8kg limit. The new Propel's shallower tube profiles compared to its predecessor are a clear indication of Giant's choice to make this an all-rounder, rather than a bike reserved for the flat days. 

However, it's not all about the weight loss. Giant claims improvements across the board, including a 6.21-watt better aerodynamic performance, an overall stiffness increase of 9.2%, and a boost in compliance of a whopping 85% thanks to a new integrated seat post design. That's all accompanied by a redesigned cockpit that Giant says is now faster and easier to adjust or work on.
