On 21 August 2016, Swiss racer Nino Schurter crossed the finish line in Rio and threw up his hands in celebration. On the last lap of the men’s Olympic cross-country race, he’d stormed away from his main rival Jaroslav Kulhavy to clinch the coveted gold medal. It must have been a sweet victory, not only for the five-time World Champion as he filled the gap in his trophy cabinet, but also for the Scott engineers, whose work on the new Spark had been focused largely on achieving success in Brazil.
The bike that crossed the finish line first was the product of three years of prototyping and testing by Nino and Scott. Despite the winning pedigree of the old Spark, the team identified various improvements that could be made. Their first job was to incorporate 29in wheels without compromising Nino’s really low cockpit set-up.
In the past, he’d found he could only achieve his optimal ride height with 650b wheels. Smaller hoops have a noticeable disadvantage when it comes to rolling speed though, and creating a bike that rolled as fast as possible was seen as critical for the hardpacked Olympic course. Nino’s existing set-up was used as the starting point for the geometry and by shortening the head tube, slackening the head angle and using drop-in bearings, almost 20mm was dropped off the stack height and the magic numbers were achieved.

Even with the changes, Nino ran a 90mm Ritchey stem flipped to give a 25-degree negative rise and a 680mm Ritchey Superlogic Carbon bar with five degrees of downsweep — an almost unridable set-up for most people.
Shock move
One of Nino’s requests for the new bike was improved pedalling stiffness. Scott’s answer was to move the shock from under the top tube to a new vertical position above the bottom bracket (BB). This allowed them to slim down the top tube and bulk up the BB area, where torsional forces are highest. The result is a frame that’s both stiffer and lighter, and with a lower centre of gravity too. Making the Spark 1x-specific and using Boost hub spacing allowed the engineers to shorten the chainstays, again increasing stiffness.
