Scott has just unveiled the Spark RC 2027 — a ground-up redesign that builds on years of World Cup victories and Olympic hardware to deliver the lightest, most refined cross-country race bike the brand has ever made.
The Spark RC has always been in a league of its own when it comes to XCO dominance. World Championship titles, Olympic medals, and a string of World Cup victories tell a story of a platform that simply keeps winning. Now, for 2027, Scott has pushed the formula even further — a completely new frame, a rethought suspension system, smarter component integration, and a spec sheet that reads like a wish list for any serious racer.
The new HMX Carbon Gen5 frame tips the scales at just 1,427 grams in its lightest configuration — a genuine step forward that you’ll feel every time you put power down on a climb.
Cross-country has changed dramatically over the past few years. Courses are faster, more technical, and demand a bike that can climb like a hardtail and descend with real confidence. Scott’s answer is a new platform built around three clear goals: meaningful weight reduction, improved ride dynamics, and easier serviceability — in competition and in daily use.
The result is a bike that stays true to the “Spark essence” while arriving with smarter integration, a refined suspension, and a broader range — from full World Cup builds used by the SCOTT-SRAM MTB Racing Team all the way down to more accessible options.
The 2027 Spark RC retains the integrated shock concept that made the previous generation such a talking point, but the kinematics have been completely reworked. Running 120 mm of travel front and rear, the new suspension system is tuned to deliver optimal support on the way up and real descending capability when the trail turns technical.
On the World Cup EVO — the flagship build available right here at Cycle Lab — that suspension is brought to life by the RockShox SID Ultimate Flight Attendant up front and the RockShox SIDLuxe Ultimate Flight Attendant at the rear. The Flight Attendant system reads the terrain and adjusts the suspension in real time, so you’re always in the ideal setting whether you’re sprinting out of a turn, attacking a climb, or carrying speed through a rock garden.

The Scott Spark RC World Cup EVO is the build that bridges the gap between the pro peloton and the trail outside your door. Every component has been chosen to maximise speed, accuracy, and control — and it shows from the first pedal stroke.
Power moves through a SRAM XX SL Eagle AXS Transmission 12-speed drivetrain, complete with a power meter built into the crankset and wireless electronic shifting via the AXS Rocker Pod Controller. Stopping power is handled by the SRAM Motive Ultimate 4-Piston brakes with 180 mm front and 160 mm rear rotors — confidence-inspiring in both wet and dry conditions.
Rolling stock is a highlight. The Syncros Silverton CF1 wheels feature a 30 mm carbon rim, carbon spokes, and a tubeless-ready setup for reduced weight and improved puncture resistance. Both ends are wrapped in the Maxxis Aspen 29×2.4” Race Edition tyre — fast rolling and confidence-inspiring in the loose-over-hard conditions that define modern XCO courses.
The new Syncros IC-M100-SL2 HMF Carbon handlebar measures 740 mm wide with a -10° angle and 7° back sweep — a modern, race-focused position that gives you control without sacrificing comfort on longer efforts. Cable integration is handled by the Syncros Octopus Gen2 system, keeping the front end clean and aero.

What makes this generation genuinely exciting is that Scott haven’t chased a headline number and called it done. The weight reduction is meaningful, but the bigger story is that every gram removed was justified by a performance return — whether that’s improved acceleration, sharper handling, or better suspension response. The HMX Carbon Gen5 frame is stiffer where it needs to be and engineered for long-term reliability in demanding race conditions.
The Flight Attendant suspension adds a layer of intelligence that lets you focus on the race rather than fiddling with settings on the fly. The moment the system detects a change in terrain, it reacts — no manual input required. It’s the kind of technology that sounds like a feature until you’ve ridden with it, and then you can’t imagine going without it.
Serviceability has also been a focus. Greater suspension compatibility, easier maintenance access, and the Syncros Octopus Gen2 cable integration all point to a bike that’s been designed with real-world use in mind — not just the podium photo.
Whether you’re lining up for a club race, building towards a national championship, or simply want the best XC bike money can buy, the 2027 Spark RC World Cup EVO is a compelling choice. It comes race-ready, proven World Cup genetics, and it’s available right now at Cycle Lab.
