Chiru Alpin - Alpine Gravel
Frame Features & Specifications
Designed as the Mountain-bikers gravel bike. Choose the Chiru Alpin when the going gets steep, big mountains, big descents. The Alpin can tackle fast dirt roads as well as technical terrain thanks to the massive tyre clearance that lets you run between 43c and 55c tyres.
The modern frame geometry fits 4 bottles, bosses for bolt-on top tube bag, Full Frame Bag or Racks and fenders.
The frame geometry is designed around a 430mm rigid fork, or Fox 32AX suspension fork
