Wilier Jena (carbon gravel; Jaroon is the aluminium sibling)

The Jena is Wilier's carbon gravel platform, named in keeping with the brand's tradition of naming bikes after lakes, mountains and Italian places (Jena is a stylised reference matching the Jaroon — the aluminium sibling — which itself takes inspiration from off-road exploration). Designed in Rossano Veneto in the Veneto region, the Jena was launched around 2020 as Wilier's answer to the rapidly growing gravel market and was further refined by the time the GRX Di2 12-speed groupset arrived. Its signature kinked sloping top tube and Kamm-tail down tube were drawn up by Wilier's in-house design team to give standover clearance for technical riding while keeping a fast, race-oriented aero silhouette. Although frame manufacturing is Asia-based, the geometry, ride-tuning and finishing are Italian — Wilier sells it as a 'fast gravel' bike rather than an adventure tourer, reflecting the southern-European racing-gravel scene around Strade Bianche and the Italian gravel calendar.
