Like Giant’s other high-end race frames, the new Propel Disc uses an integrated seat post (ISP). Giant’s product information claims than an ISP saves weight, improves compliance, and is more aerodynamic than a traditional post.

Another significant change is found in at the bar and stem. In the style of many aerodynamic road bikes–Specialized’s Venge ViAS and Trek’s Madone for example – the Popel’s brake and derailleur-control lines are almost completely internally routed. They run into the handlebar and, likely, though the stem before entering into the frame.
