I just built a 2010 Sortie Frame (an EBAY special) using parts that I took from my 2008 Mission Custom (sold the frame)
Why did I do this? I wanted a bike that climbed a little better and felt that I really never used the full 6 inches of suspension - I felt that I was lugging it up long climbs for nothing. The Sortie presented itself and jumped. The Mission frame practically sold itself!
Build specs (same on '08 Mission and '10 Sortie):
Magura Thor AM 140mm fork, 20mm T/A
XTR Real Der
SRAM X7/xtr/sram drivetrain
Hayes HFX-9 Carbon brakes, 7" rotors
819/hope 2 20mm front
Easton Monkey Lite CNT bars
Truvativ AKA stem 90mm
Thomson Elite Post (Mission had original Easton EA50)
WTB Silverado Seat
Maxxis/Kenda 2.35 tires
The other main difference is the Sortie has the newer Fox RP23 XV/Boost shock vs the 2008 RP23 on the Mission.
The Mission was right at 31 pounds for this build and I can say that the Sortie is a few pounds lighter (will weigh later). I guess about 2 pounds
The ride ......
Most rides in the Colorado Front Range start with a climb, so my choice of trails, Hall Ranch in Lyons CO, should have been a good test ride. Right out of the car, I immediately noticed the weight difference and, probably more so these things:
-no real need to lower the travel on the fork, the steeper geometry took care of the climbing woes on the mission.
-No real need to engage Propedal. I credit the shock evolution for this, though not sure what the deal is with this yet.
The Sortie kicks the snot out of my Mission in terms of climbing - I can say this even with out finding the sweet spot for suspension settings.
On rough, rocky terrain, the lower BB height of the Sortie was obvious because I hit the pedals a bit more, but with a bigger-than-spec Fork, the BB was really only <1/2" lower than the Mission - a price I am willing to pay. Being a numbers geek, I crunched the geometry numbers vs fork travel and came up with a HTA of <69.5 on the Sortie with a 140mm fork - right where I want to be.
The Sortie steers faster, as expected, and I really enjoyed the low speed maneuvering capabilities in rough terrain. This was also one of my goals vs the Mission.
Downhill - Here's the other side of the coin.... the Mission crushed ever DH I ever threw at it and was totally unflappable. I knew I'd be giving up some of this... I learned this the hard (and painful) way today by stuffing the fork while dropping off a big rock and went OTB.
Not once, but twice in 5 minutes in a really unforgiving rock garden - oh, well, that's mountain biking I guess
This isn't a fault of the Sortie. I just forgot to realize that I was not riding a 68 degree HTA, long wheelbase bike today. I just need to re-learn a few things Like how to get my a$$ off the back of the seat and get my weight located properly. I also need to figure out the shock/fork pressures.
Unfortunately, I whacked my rear derailleur hard enough to bend the hanger (new one ordered). I fixed this on the trail and proceeded, perhaps slower and more tentatively than I would have with out scrapped and dings, back to the car.
As I type, I can feel the 3 Advil kicking in...
More to come. Over all I am please with the switch.
Now, how to get a Mission with a 160mm fork to add to the quiver......
