Sortie v Mission
Looking at ordering a new diamondback, really just want an all around bike. Here in Michigan, so most of it is singletrack, with Boyne and Cannonsburg really being the only downhill. Whats the real difference between these two bikes?
Sortie xc/trail, 5" frame, 130mm travel suspension, 2.1" tires for trail riding..about 27LBS.
Mission AM (all mountain), 6" frame, 150mm travel suspension, stout-burly frame, gnarlier fatter tires for flying down hill translates into not the fastest pedaler but does pedal well. 2.5" frnt/2.3" rear tires. about 32lbs...
Both are great all round bikes but if your all round is mostly pedaling and climbing and you want a bit of speed and dont want a heavy burly 30lb bike to pedal about then the sortie is your blue pill.
If you want to be able to still pedal a lot and dont mind giving up pretense at racing but mostly you want to head down slope, and off drops, make jumps, carreen across rock gardens, then the mission is the red pill. It can even flirt rather competently with some freeride.
Understand that there is quite a bit of overlap between the two, but if your primary activity occurs at their extremes one will be more suited then the other.
Let the good times roll.
I own a Mission, and I've ridden several Sorties. The 2 have more similarities than differences, in my opinion. Both pedal efficiently, both have excellent handling in most situations, and both are capable of a wide range of riding. Like Moozh said, there's a lot of overlap. The Sortie is more on the trail riding side of AM, and the Mission is more on the freeriding side.
What kind of rider are you? If you like to launch off everything that looks like a jump and always push your limits when the trail points down, the Mission is a better choice. It's geometry and components are better suited for that. If you prefer to keep both wheels within a foot of the ground, the Sortie will be a more fun bike. It feels more responsive for trail riding and climbs better.
