The Stumpjumper line for Specialized this 2011 underwent some changes. The Stumpjumper FSR 26” will no longer have the Brain feature and the S-Works models will have Roval Control SL wheels with carbon rims like the Epic line. It will also feature 2×10 drivetrains. The Specialized Stumpjumper S-Works 29er carbon frame weighs 1,055 grams while the 26” model weighs 920 grams.
For middle and high-end models, Specialized incorporates 90mm travel Future Shock with dropouts that are good to go with the OS28 end caps. This results to stiffer wheels and sturdy rides. These wheels can fit RockShox and Specialized forks. 15QR caps are offered for the front wheel while the rear will get standard 135mm choices.
The Stumpjumper S-Works has shaped seatstays with a 27.2mm seatpost. It will also have Press Fit 30 BB’s and dropouts that are hollow. The Stumpjumper hardtails can be a choice of carbon or alloy. It also has a singlespeed hardtail which becomes 100 grams lighter than its 2010 version. The update singlespeed Stumpjumper has slider dropouts and a Fox fork.
Specialized also releases the Evo variants for Stumpjumper. It comes in two models, the Stumpjumper FSR Evo and the Stumpjumper Evo Trail 29. The FSR Evo has an aluminum frame with no Brain. The fork is a 150mm Fox Float and highlights to have bigger tires and Traverse EL wheels. With handlebars measuring to 720mm, the Stumpjumper FSR Evo also carries a Gamut shift guide on ISCG tabs.
The Stumpjumper Evo Trail has a 100mm travel fork with a 1×10 drivetrain and chainkeeper. It also has thicker wheels and larger tires.
