Modern performance geometry demands more stability due to increasingly rough terrain combined with higher speeds. A 71.5-degree headtube angle ensures you have faster handling. The Astr family features a steeper seat tube (74 degrees), improving climbing performance and power transfer.
The product developers kept the chainstays as short as possible to accommodate tyres up to 52 millimetres without losing the feeling of responsiveness when accelerating. In addition, the bottom bracket is a bit lower. This ensures you have more stability at high speed. Finally, the head height is lower, so you sit more aerodynamically on the bike. In summary, this boils down to a modern competitive geometry, tailor-made for the ambitious gravel racer.
