Specialized’s much-loved Stumpjumper gets a revamp, sporting less weight, less angles and more reach in both 27.5 and 29″ versions.
Three distinct new models and two wheel sizes, the new Specialized Stumpjumper gets the longer, lower, slacker treatment whilst also shedding some serious weight in the process.
The all-new Stumpjumper falls into four different model groups, the Stumpjumper, Stumpjumper ST, Stumpjumper EVO and Stumpjumper Women’s. All come with minor tweaks designed to give a very different ride experience.
Overall, the changes to the frame are considerable compared to the outgoing offering.
Stumpjumper.
Specialized have dropped the hybrid carbon front, alloy rear options from their mid-range frames, with all-alloy or all-carbon now available. The full carbon frames feature the same 11M construction from the S-Works all the way down to the Comp Carbon.
Those hybrid frames that jump to full carbon will benefit from a 550g weight saving, while the full carbon models of old still see between 100 and 250g fat trim.
In the suspension department, the 29″ wheeled Stumpjumper gets an increase of 10mm to 140mm, while the 27.5″ retains its 150mm travel. A more progressive leverage ratio has been designed to work better with a linear shock tune for better use of travel in more trail conditions. Rear shocks are metric throughout the range, with a shift away from Ohlins on everything but the Pro EVO model that uses a TTX Coil shock.
Out front, the head angle has been slackened again, with the 29″ version adjustable between 66.5 and 67, and the 27.5″ version between 65.5 and 66 degrees, both by way of the shock-mounted flip chip.
Seat tubes have all moved to 34.9 across the board, with the seat tubes being trimmed by between 15-20mm depending on size to accommodate longer dropper posts.
While previous years may have been Ohlins and SRAM heavy in terms of dampers and drivetrain, expect to see a lot more Fox and Shimano fitted to all three variations of the new Stumpjumper.
Prices start at £2500 for the Comp Alloy and rise to £8000 for the S-Works.
Stumpjumper ST.
Designed as a bike for more lively riding, the Stumpjumper ST loses travel compared to the standard Stumpjumper, sporting a 130mm fork regardless of wheel size. Sitting back to back with the Camber though, the head angle has been raked out slightly, again adjustable via the flip chip with 29″ adjustable from 67.5 to 68. 27.5 is adjustable from 66.5 to 67.
Reach has also been stretched to between 10-20mm on the 29″ version and 25-35mm on the 27.5″.
Stumpjumper EVO.
The heavy-hitting Stumpjumper gets more travel where the ST has less. Fork travel rises to 150mm on the 29″ with rear travel at 130mm, while the 27.5″ wheeled model gets a 160mm fork and 140mm out the back.
Geometry-wise, the EVO sports the same geo in the high position as the others models but loses 0.5 degrees and 5mm BB height in its low position for more aggressive handling.
The EVO model also sports coil dampers, more powerful stoppers, bigger, more aggressive tyres, wider bars (800mm instead of 780mm) and a Wu Command Post.
