The Scott Addict RC Ultimate Bike weighs 5.84kg as measured — no tricks, no missing components, complete with saddle and tape. By that number it's one of the lightest production road bikes ever built, and the way Scott got there is as interesting as the number itself. The frame uses a PP Mandrel construction technique — borrowed directly from Scott's mountain bike development program — where a solid polypropylene mandrel replaces the traditional inflated bladder used in carbon layup. The mandrel creates a completely smooth interior with no voids, no wrinkles, and no excess resin cured into the structure. The result is a frame that contains only what it needs, nothing more: walls as thin as 0.6mm in places, a raw frame weight of 599g in size M, and a fork at 270g.

Getting there required a different kind of engineering process, too. Scott partnered its Head of Road Bike Engineering with a simulation engineer running finite element analysis from the very start of the design — not as a validation step at the end, but as the primary design tool throughout. The FEA model breaks the frame into 26,000 elements and maps 200 layers of carbon across the structure, identifying exactly where material is needed, how much, and in which direction fibers should run. The downtube carries the majority of the frame's load and was the first section optimized; from there the team worked outward. The seatpost clamp was moved inside the frame. The chainstays run to a precise 410mm. Axles feature a self-centering design to save weight while ensuring precise placement. Every detail has a reason, and every reason starts with weight or stiffness — usually both.
The cockpit is the Syncros IC-R100-SL Carbon Combo: a one-piece integrated bar-and-stem in full carbon. Scott claims a 12-watt aerodynamic improvement from the revised design, which uses a slight flare in the drops to narrow the hand position on the hoods — an increasingly common approach across aero-optimized road bikes, but one that…
