It isn’t just a new Stumpjumper FSR coming for 2016 but a Camber too. With same front triangle so SWAT door and the multitool under the dampermount on the carbon models.
The big news from this years Camber are:
437mm chainstays for 29″, 420mm on 27,5″
27,5″ wheel option
No EVO, 120mm for all 29ers, 130mm for 27,5″
Yes, you read right, the new Camber is getting more travel and a new Brain, like the old regular Stumpjumper FSR.
An updated Brain called Trail Brain. The first 25%, sag, is always active so the Brain activates first when pressing hard than that.
