The UCI Approved Astra maintains its vocation of road cycling but increases stability and comfort. It's light, but without pushing the carbon to its limits, preserving Basso's racing DNA but makes it transversal, for those who are not professional athletes, but who want to ride their bikes every day. The new frame features dropped seatstays, a 12mm higher stack height and 3mm shorter reach, creating a slightly more relaxed riding experience. The 35mm tyre clearance allows you to mount wider tyres and venture beyond the tarmac on to light dirt roads.
