Specialized Stumpjumper FSR Review

The full suspension versions of the Specialized Stumpjumper mountain bikes bring heavy-hit taking rear shocks to the table while retaining the same quality of performance and components elsewhere. The range is intended to give great all-round performance which will put you in a good position whether you need to roll quickly up the climbs or descend confidently. More than three decades of development have brought us to the 2012 editions, but what kit can you expect to find onboard?

The basic Specialized Stumpjumper FSR Comp has an M5 hydroformed alloy frame, a Fox Evolution fork with 140mm of travel and the pièce de résistance in the form of a Custom Fox Triad II rear shock with Autosag. This has a three position compression switch for changing between full lockout, open and ProPedal modes.

SRAM X7 and X9 components give you 20 quick-shifting gears and there are Custom Avid Elixir 7 SL hydraulic disc brakes with 200mm rotors at the front and 180mm at the rear. Rims come courtesy of Roval and are paired with Specialized Purgatory Control (front) and Ground Control (rear) tyres.

Specialized Stumpjumper FSR Comp

The Specialized Stumpjumper FSR Comp EVO sticks with the M5 alloy frame but adds a RockShox Revelation RL 150mm travel fork and a Custom Fox RP2 rear shock with AutoSag technology. You get the same SRAM components and Avid Elixir brakes, while a Specialized Butcher Control tyre sits at the front, with a Purgatory Control tyre giving you the grip you need at the rear end, both on Roval rims.

The Specialized Stumpjumper FSR Comp Carbon is a natural evolution of this range, introducing the light and rock solid FACT IS 9m carbon front triangle to the M5 alloy rear triangle to give you a good balance of weight reduction and affordability. This model, being carbon, sees the weight drop to just over 12kg. The Fox Triad II rear shock returns, again with Autosag, while a Fox Evolution F140 RL fork makes an appearance, the 140 part referring to the 140mm travel. The drivetrain and brakes remain the same, with the Specialized Ground Control replacing the Purgatory Control tyre at the rear.

Specialized Stumpjumper FSR Expert

The Specialized FSR Expert Carbon EVO gets its own frame geometry using the same combination of FACT carbon and M5 alloy. The customised Fox RP32 Adaptive Logic shock comes with a boost valve and the 3 compression settings of its stable mates. The Fox Factory Float fork delivers 150mm of travel and some SRAM components get upgraded to the carbon equivalents for further weight loss, with the SRAM X0 making an appearance.

The Specialized Expert Carbon still features the carbon/alloy mash-up on the frame. Fox and Specialized have worked together to produce the rear shock with its remote Brain technology and trail-tuned inertia valve. SRAM X7, X9 and X0 groupsets are mixed into this tasty recipe while the Custom Formula The One R hydraulic brakes allow for tool-free adjustments at the front and rear for easy maintenance.

Specialized Stumpjumber FSR S-Works Carbon

The Specialized Stumpjumber FSR S-Works Carbon perches precariously at the top of the range, bringing a full FACT 11m carbon frame to the table, with no alloy to be found. The Fox / Specialized rear shock is back while the Future Shock S140TA fork lets you pick between 140mm and 115mm of travel.

The SRAM XX groupset shows that this bike means business, as do the Custom Avid XX World Cup R brakes. Roval Control Trail SL rims once again sit on S-Works Purgatory (front) and Specialized Ground Control (rear) tyres. At £7,000 this bike is only for the serious minded.
