Ridley ASTR Gravel Bike

• Aero-To-Weight
  The Astr is also built according to the 'aero-to-weight' principle. The aero-to-weight principle is the trend in the cycling peloton. Ridley no longer makes riders choose between aerodynamics and weight but combines the best of both worlds.
• Diffuser Fork Crown
  The fork crown has an integrated diffuser to reduce drag. The airflow passes more easily through fork crown while extra energy is added to it. The result is that the airflow passes the downtube more easily without pushing the bike back. At the same time there is less drag in the area behind the fork and headtube.
• Tyre Clearance up to 52mm
  The Astr family features groundbreaking tyre clearance: 52 millimetres with a 1x setup and 47 millimetres with a 2x setup. This is no coincidence, but the result of a carefully considered vision from their product developers. They anticipated the increasing technical demands of gravel racing and the growing desire among riders for more grip,
  stability, and versatility.
• Performance Geometry
  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. 
• Removable Front Derailleur Clamp
  A removable front derailleur clamp ensures a sleek, streamlined appearance when using a 1x setup. In collaboration with Wolf Tooth, Ridley developed a custom chainguide and chain catcher perfectly tailored to fit their frames. To maintain a clean and polished look, they’ve also designed a specialised cover to seamlessly replace the clamp when it’s
  not in use.
• Universal Derailleur Hanger
  The universal derailleur hanger (UDH) is the new standard in the cyclingworld. Not only is this derailleur hanger compatible with all modern
  shifting groups, it also protects against derailleur breakage and chain drops.
