We had the opportunity to get our hands on the titanium version of Salsa's Fargo, and let me tell ya...Its hot to death. Titanium makes a sweet material for this kind of bike. When you are out there miles away from any remnants of civilization you have got to have faith in your equipment and Ti is among the lightest and most durable materials out there.
The parts chosen For this bike are Shimano XT all around with Avid BB7 brakes. Smart reliable parts for long expeditions.
