Interbike 2009 – Specialized’s 2010 S-Works Stumpjumper, 29er Hardtail and Enduro

INTERBIKE 2009 – Specialized was showing off their new S-Works mountain bike models for 2010, including the lighter, stronger (and longer travel) Stumpjumper, the race-ready 19lb 29er Carbon Hardtail and the new full-carbon S-Works Enduro all mountain rig.

First up is the $7,700 S-Works Stumpjumper.  Completely reworked from the ground up, it went from 120mm to 140mm in travel, dropped weight (it comes in around 22lbs for a long travel trail bike!) and gets some serious go fast components.  Perhaps coolest is their carbon FACT crankarm with triple rings mated to a SRAM XX rear gearing and derailleur.  Specialized offers these cranks with spiders capable of running XX rings, too, if you wanted to convert the Stumpjumper to a 2×10, but as it is you have 30 speeds to choose from.

Hit ‘more’ for lots of pics of the Stumpjumper and Enduro.  It’s in the video above, but photos and ride review of the S-Works 29er Carbon Hardtail are on this post, and you can check out their 2010 road bikes on this post.  Read on and you will want a new mountain bike…

The 2010 Specialized S-Works Stumpjumper FSR comes either as a complete bike or frameset ($2,800).  It has a FACT 10m carbon main triangle and seat stays with M5 alloy chainstays. There’s also a $5,500 Pro model (and $2,000 frame) that has a FACT 9m carbon front triangle with all alloy stays.  The frames include the internal headset, seatpost and clamp, front derailleur and rear shock.

The carbon S-Works cranks trickle down the Stumpjumper for 2010.  It has standard 22/32/44 rings, but you can swap it out for a double if you’re a superstar.

Count ‘em…10 speeds in the rear, and the SRAM XX rear derailleur to move the chain up and down.

Full cartridge bearings  connect the links and shock.  The Fox/Specialized rear shock has the Brain Fade w/ remote inertia valve that acts as the platform control.  You can set how sensitive you want it to be, which controls how firm the ride is by requiring more or less of a bump to initiate the shock’s movement.  The rebound adjustment is found on the shock.

Above and below, note the cable runs beneath the bottom bracket.  This is perhaps the only questionable design aspect.  I don’t think the rear suspension travels enough to warrant that much cable slack, so if this were my bike, I’d probably pull some of that out…seems like it’s just begging to get snagged.

The matte carbon finish is highlighted with a few glossy sections (look inside the triangle seat tube reinforcement), creating a stealthy looking frame that could still go out on the town.

The front suspension is Specialized’s Future Shock S140TA (travel adjust), which goes from 115mm to 140mm of travel, and uses an internal Brain Fade adjustment to control bump sensitivity.  It has a 1-1/8″ to 1.5″ tapered carbon fiber steerer tube.

The bike comes with Specialized’s Roval XC SL wheelset.  The radial spokes on the non-disc side save a little weight, helping the wheels achieve their 1385g weight (per pair).  Spokes are DT Swiss AeroLite, skewers are Titanium and they have an oversized axle to increase stiffness.

The brakes are custom Avid XX R with magnesium caliper and lever body, carbon blade, Ti hardware package.  Small and Medium bikes get 185mm / 160mm (front / rear) rotors, and Large and XL frames get 203mm / 185mm rotors.

2010 SPECIALIZED S-WORKS ENDURO

The S-Works Enduro comes in at $7,200 as shown, and a $2,800 frameset is also available that includes a Fox RP23BV, headset, Specialized Command Post 100mm adjustable height seatpost and seat binder.

The frame is FACT 10m front triangle with M5 alloy stays that gets 160mm of travel (up from 150mm on prior model).  It has a built-in ISCG mount and replaceable derailleur hanger.  Total bike weight is just over 26lbs…which is ridiculous for a 160mm travel bike.

You’ll get the same custom Avid XX levers and brakes with Ti hardware as on the Stumpy and SRAM X.0 shifters.

The S-Works Enduro comes with the Specialized Future Shock E160TA that can adjust from 135mm to 160mm of travel.  It has external Rebound and Compression damping and uses a Rockshox Maxle Lite 20mm thru axle and tapered headtube for maximum stiffness.  Brake rotors are 203mm / 185mm on all sizes.  Wheels are Roval Traverse EL (1550g / pair) that can be changed to run 15mm thru axles if you felt like changing the fork.

Again with the drooping cables…you could probably just pull them up through the guides and have a slight bit more cable floating in front of your handlebar, especially since you can’t (shouldn’t) really trim the hydraulic line for the rear brake.

The chainring is Shimano XT with a 22/36 double between the Gamut shift guide and bash guard.  Small frames get a 170mm crank arm length, all other models use a 175mm.  A Shimano SLX derailleur shifts up front.

Cassette is Shimano XTR Ti 11-34 with an XTR chain.  Rear derailleur is SRAM X.0.

Big, thick bottom bracket area.

The X shaped frame increases stiffness.  The Fox RP23BV shock with Boost Valve and ProPedal adjustments help the bike perform nearly as well going up as it’s designed to go down.

Enduro models also come in Alloy frames with prices ranging from $2,800 for the Enduro SL Comp all the way up to the $7,200 S-Works model shown here.

I have a 2006 Stumpjumper FSR, my cables run tight under the bottom bracket, which has caused them to wear 50% through the aluminum frame. The cables rub against it frequently enough to wear it down significantly over time. They need a cable guide or this will happen here too.
