Hygge S-Aura 2026 UCI Approved Frameset (UD Laser)
FrameThe Hygge S-Aura is a new 2026 frameset from the Chinese brand Hygge, positioned as an upgrade to the Model S. It features UCI approval, T47 bottom bracket, UDH, and a max tire clearance of 32c (though some users suggest it may fit up to 34-36c). The frame is EPS-molded and available with 0 or 15mm offset seatpost. Pricing is around $1400-1500 USD, which many forum users consider too high compared to the Model S (~€650). The design draws comparisons to Ostro and Venge, and the paint options include a unique hand-painted landscape. However, the branding (S-AURA) and logo placement have been criticized. There are very few user reviews, and the frame has not gained significant traction on the forum.
AI Summary
Pros
- Good communication and service from Hygge (e.g., quick response, sent upgraded part for $1)
- Frame quality: no creaks, no seatpost slip, silent after 15k km on rough roads
- Option for 0 or 15mm offset seatpost, allowing better fit adjustment
