2026 Scott Addict RC Ultimate - HMX-SL Carbon & SRAM RED AXS
The 2026 Scott Addict RC Ultimate represents the pinnacle of road-racing technology. While other brands have moved toward heavier "all-rounder" aero bikes, Scott has doubled down on its climbing heritage, stripping away every non-essential gram while refining the aerodynamics to match those of the previous-generation Foil RC.
The 2026 Scott Addict RC Ultimate is the absolute pinnacle of Scott’s "Racing Concept" range. Following a significant redesign for the 2026 season, this bike has been engineered to be one of the lightest production disc-brake road bikes in the world, tipping the scales at a staggering 5.9kg (size M).
It is the choice of professionals and weight-weenies alike, utilising the exclusive HMX-SL carbon fibre layup to achieve a frame weight of under 600g.
Full specifications can be found on Scott's website here.
HMX-SL Carbon Layup: This is Scott’s most advanced carbon fibre technology. By using Nanotube-reinforced epoxy resin, the RC Ultimate achieves a frame weight of just 599g (unpainted), making it roughly 150g lighter than the standard HMX frame.
SRAM RED AXS (New E1 Generation): The bike is equipped with the latest SRAM RED AXS 2x12-speed wireless groupset. It features significantly lighter hoods, more powerful braking, and an integrated Quarq Power Meter as standard.
Syncros Capital SL Wheels: These are one-piece carbon wheels where the spokes, rim, and hub are cured together. This eliminates spoke nipples and traditional hubs, creating a wheelset that is incredibly stiff and weighs only 1170g.
Aerodynamic Integration: Despite its focus on weight, the RC Ultimate features a redesigned head tube and the Syncros IC-R100-SL integrated cockpit, ensuring total cable integration and reduced drag.
