First Look: Scott Spark 700 Plus Tuned

Few companies have pushed the boundaries of lightweight bike design over the past two decades like Scott—its sub-900-gram CR1 road bike launched the weight wars in 2003—so it came as no surprise that the new Sparkdebunks the view that plus-size bikes have to be ponderous and sluggish.

At a hair over 26 pounds for a size medium, this 120mm full-suspension carbon trail bike feels unrealistically light with those big 27.5+ tires. In fact, the Spark Plus was lighter than every other mountain bike in the Outside bike test, except for the Norco Optic 7.1, which has standard-size 27.5-inch tires. Scott didn’t fake the weight by spec’ing flimsy parts, either. The 130mm Fox 34 fork is plenty stiff for the task. And unlike the throwaway rubber that many brands resort to for curb appeal, the Spark Plus comes with a pair of meaty Maxxis Rekon+, my favorite tires in this class for their aggressive, confidence-inspiring tread and supportive but supple-feeling sidewalls and casing. (If anything, Scott could have gone a bit lighter with a faster-rolling Maxxis Ikon+ out back, but I’m not complaining.)



The other big news on this bike is the revised suspension, which spans the Spark line. Though Scott kept the single-pivot of previous generations, the old top tube–mounted design is replaced with a rocker link and pivotless swingarm. The setup retains top-end sensitivity but feels much more progressive, even through the length of the travel. Paired with a reasonably slack 66.9-degree head angle and moderate-length chainstays (438mm), the frame is surprisingly plush and capable. (The 29-inch Spark and Spark RC, which also use this new rear suspension, must surely be some of the best-feeling and lightest XC bikes going.)
