Specialized unveils 650B Stumpjumper FSR EVO models

First look at two new 650B bikes from Specialized

Once we saw that Specialized would offer 650B tires earlier this year, it could only be a matter of time before complete bikes would follow. It appears the wait is over: Specialized has just added two 650B Stumpjumper FSR models to its website.

The first — but certainly not the last — Specialized mountain bikes to get mid-sized wheels will be two bikes in the Stumpjumper FSR EVO line. 'EVO' denotes bikes in the Specialized lineup that have more gravity-oriented geometry and feature more suspension travel than the standard models.

Both 650B Stumpjumper EVO models have 150mm of rear wheel travel and sport features one would expect on a modern trail bike, including 142x12 rear thru axles, ISCG-05 chainguide tabs and internal routing for dropper seatposts.

The US$6,500 Stumpjumper FSR Expert Carbon EVO has a carbon front triangle with an aluminum rear end. Its spec’d with a SRAM X01 drivetrain, Shimano XT M-785 brakes, a custom-tuned Fox CTD shock w/AutoSag, and a 150mm RockShox Pike RC fork.

The US$3,400 Comp EVO has a full aluminum frame. The Comp Evo will come equipped with a SRAM 2x10 drivetrain with a mix of X9 and X7 components, Shimano Deore M-615 brakes, a custom-tuned Fox CTD shock w/AutoSag, and a 150mm RockShox Revelation RC3 fork.

Additional details such as geometry and availability have yet to be released.
