Scott Addict RC Ultimate.
The 2026 Addict RC Ultimate frame is 599 g (HMX-SL carbon) and the complete bike with SRAM Red AXS hits 5.84 kg — the lightest production race bike documented in Escape Collective's scale-out tests this year.
The Verdict.
Gavler Meta-Score
“The lightweight king at the 2026 production scale-out: 599 g frame, 5.84 kg complete with SRAM Red AXS. Buy this if your weekly riding includes major climbs and you weigh the bike before you weigh yourself. Skip it if you ride mixed terrain — the Tarmac SL8 and the Madone SLR 9 are better all-around picks at this price.”
The Gavler Verdict
Precision Engineering
599 g HMX-SL Frame (Escape Collective Scaled)
Independent weigh-in by Escape Collective documented the HMX-SL frame at 599 g with the matching fork at 270 g — the lightest production frame at this price tier.
5.84 kg Complete Ride-Ready Weight
Complete bike with SRAM Red AXS, saddle, and bar tape but without pedals or cages, per Escape Collective independent scale-out. Under the UCI minimum without ballast.
HMX-SL Nanotechnology Carbon Layup
Scott's highest-density carbon process uses a nanotechnology resin-reduction step that increases fiber density per square centimeter of frame surface. Disc-brake-specific layup.

The Scoreboard
Score 8.9 reflects the genuinely class-leading climbing performance offset by the aero-tier trade-off versus the all-arounders ranked above. Expert consensus 90 reflects Escape Collective / Velo / Cyclist / Cyclonline / Gran Fondo convergent positive reviews; community rating 87 reflects the bike's specialist positioning — climbers love it, all-arounders pick the Tarmac SL8 or Madone SLR 9 instead.

Global Critique
“The Ultimate's HMX-SL frame tipped the scales at 599 grams, with the fork weighing 270 grams. A complete ready-to-ride Ultimate level bike including saddle and tape but missing out front mount, pedals, and cages weighs in at 5.84 kg.”
“Scott Addict RC is brilliant, plus it's the new lightweight king.”
“The 2026 Addict RC stands out for its surgical agility. The front end is extremely precise, allowing for rapid corner entry and millimetric corrections.”
“The build quality of the Addict RC Ultimate is defined by the use of HMX-SL carbon fiber, the Swiss manufacturer's most advanced material. The layering process utilizes nanotechnology that reduces the amount of resin required.”
