Changing a Stumpjumper into a Camber

[Grease_Monkey]

So I bought a 2016 Specialized Stumpjumper (Boost) because it suited the riding I was doing very well. From when I purchased it I have changed pretty much every component on it to suit me - so just up front selling the bike or frame is just not a desirable option...

 

The stage racing/marathon bug has bit me hard, and I would like to change my current 135/150mm set up to that of a Camber - 120/120mm. As far as I know the Camber and Stumpy share a frame and I would like to take advantage of this and change my Stumpy into a Camber.

 

Dropping the forks travel to 120mm is easy. But, concerning the rear end I have no clue as to what I need to do. Does anyone here know what parts I would need or what needs to be changed to achieve the above?

 

Of course if it ends up being crazy expensive or just not possible I will probably sell the bike and just buy a Camber, but I really don't want to go that route if at all possible.

 

Edit: Reason for the change is that on long climbs I just can't get my weight over the front of the bike enough, and I also feel like I am too far behind the bb for pedaling efficiency - so just lowering the bars won't solve the problem. Weight not too much of an issue atm...

Bump.

Dropping the fork alone will change effective seat tube angle bu roughly 0.5 degrees for every 10mm drop.

Either by lowering the travel, removing spacers, or (heaven forbid) a negative drop stem.

That'll mos bring you into a better climbing position. All this you probably know.

But then dropping the rear in addition will surely negate this effect.

If I'm not mistaken you will need a new yoke for the rear to attach the shock. So you'll need to contact Spez or a concept store for this gai.
