For the Amira rider, the road is her racecourse. Whether edging out the field for the sprinter’s jersey or vying for Queen of the Mountain, these speed-hungry riders and racers want to push their limits and the limits of their bikes. Since these women are focused on performance, they demand an ultralight, stiff, and efficient bike for all-out speed.
WHAT FACT IS 11r SL4 carbon frame with women’s performance geometry and carbon layup/tubesets, plus shaped seatstays, oversized down tube, and one-piece OSBB/chainstay.
WHY To achieve the lightest weight, stiffest, and most performance-focused bike for female road racers and enthusiasts.
HOW Our Women’s Performance geometry features shorter chainstays and a shorter head tube, which optimizes positioning for maximum power and efficiency. By engineering a wide, triangulated stance between the brake bridge and seatstays, and using a large diameter down tube and oversized BB, we build more lateral and torsional rigidity into the frame for faster acceleration.
TAPERED HEAD TUBE/STEERER TUBE
WHAT Strategically designed head tube/steerer assembly that tapers from 1-1/8” at the top to 1-3/8” at the crown.
WHY Increases strength and stiffness for greater steering precision, without making the ride too harsh.
HOW Tapering the head tube to be wider at the base—where it integrates with a 1-3/8” recessed lower bearing—creates a naturally stiffer junction. The gradual transition of carbon fiber from top to bottom eliminates any sharp angles that could cause a weakening of the fiber.
WHAT Body Geometry Women’s Oura, Jett Gel and Riva saddle, plus size-specific components including an S-Works crankset/chainring option (52/36) and women’s carbon handlebar with improved position and shallow drop.
WHY Optimizes fit and performance for the female anatomy.
HOW We spec each bike individually based on frame size, geometry, and fit research. Through pressure mapping testing with Dr. Roger Minkow, we optimize the foam densities and cutaways in our saddles to relieve soft tissue discomfort.
