Whats up with this new Giant Propel?
The Nerds are back with another group episode, this time with Ronan doing his best Aussie impersonation since Dave is away on holiday.\nOn tap this week is a detailed introduction of Giant\u2019s new Propel aero road bike \u2014 and its wild Cadex 50 Ultra Disc carbon fiber wheels \u2014 along with a frank discussion of what\u2019s going on with Wahoo\u2019s revamped Speedplay pedals. And as always, we wrap up with a round of Ask a Mechanic, including a little incident Caley himself had with a little hydraulic fluid.
