The Specialized S-Works Enduro 29 was one of the most popular bikes on the enduro race circuit in 2013 thanks in part to a killer combination of fast-rolling 29-inch wheels and short,16.9-inch chainstays that made for incredibly nimble cornering performance. What's more, the S-Works Enduro 29 sports a whopping 155mm of rear suspension travel, clearance for tires up to 2.5-inches wide and a slacked out 67.5-degree head tube angle.

To get those numbers, Specialized engineers used an unprecedented, more -forward seat tube position that, in conjunction with a revised FSR suspension design, creates a 29er capable of massive rear travel while remaining an efficient pedaler.

The Enduro 29 comes equipped with the popular SRAM XX1 drivetrain and SRAM Trail XO four-piston caliper brakes. Perhaps the only downside of the Enduro 29 is that in order to run a two chainring system, you have to use a special mount Specialized calls the "Taco Blade"-a formed aluminum plate that mounts to the main pivot and chainstay. The other downside for many people is the price. At $9,250, the S-Works Enduro 29 was one of the spendiest bikes in the Enduro Compare-O.

With an eye-catching FACT 11M carbon fiber front triangle featuring Specialized's X-Wing frame design-a trademark configuration that ties top and downtube elements together-the Enduro is a looker. More than just an exercise in cosmetics, the X-Wing is functional, making the frame tighter, stiffer and stronger.

Out back, a welded M5 aluminum rear triangle links to a Cane Creek Double Barrel Air CS shock with its Climb Switch lockout for efficient uphilling. Its foreword counterpart-the much raved-about RockShox Pike RCT3 fork-provides a relatively balanced, 160mm, front end response.

The Enduro 29's cable routing is very clean and all internal, including routing for an included Specialized Command Post IR dropper post. Also integrated is Specialized's clever SWAT-Storage, Water, Air, Tools-system that utilizes the bike's nooks and crannies to carry repair essentials. Tucked underneath the water bottle cage is an integrated multi-tool, while a handy chain tool and extra master link hide underneath the stem cap.

Finally, with an asking price of nearly $10k you knew the wheels would be top shelf too. In the case of the Enduro, that's a pair of Roval Traverse SL 29 carbons that employ Specialized's hookless technology, and ride on a DT-Swiss hub internals. Wrapped in Specialized Butcher and Purgatory tires, the kit should make for a sweet, light and grippy combo.

To build a long-travel 29-inch all-mountain bike with chainstays as short as a160mm 26er is no small feat. To have it weigh in at a scant 27.31 pounds is an even more remarkable achievement. Needless to say, we couldn't wait to point this bike down Braille Trail and get radical.
