32mm clearance is the number that matters here — that's aero-bike territory on a frame that keeps endurance geometry, a combination most pure aero platforms don't attempt. The tube shapes come from Cube's time trial and road race development, filtered down through five build tiers, from SRAM Rival at €2,999 up to the SLX's SRAM Force build at €3,999 — with the Dura-Ace Di2 SLT sitting above that as the range-topper. An 8.1kg Pro build with Ultegra Di2 and carbon wheels at €3,299 is the pitch: aero detailing without the race-bike aggression, priced for riders who'd never consider a dedicated aero frame.
