The Sirrus brings the speed of a road bike with the comfort and confidence that comes with a flat bar. For exercise, commuting, or hitting the open road, the ideal bike is versatile, light, and fast—one that’s comfortable enough for recreational rides, but packs enough performance for the occasional event ride or triathlon.
WHAT All-new double butted A1 Premium
Aluminum Sirrus frame featuring fitness
geometry, smooth welds, full fender
and rack compatibility, internal cable
routing, and improved tire clearance.
WHY To create the best fitting, most versatile,
and smoothest riding fitness-inspired bike.
HOW Our engineers optimize the frame’s
tube shapes and diameters to maximize
compliance and minimize weight
for greater comfort and handling.
By lengthening the chainstays and
modifying the frame, we’ve built in more
tire and fender clearance this year.
FACT Carbon Fork
WHAT Fork constructed from
lightweight FACT carbon.
WHY Reduces bike weight and helps absorb
vibrations from road so cyclists can ride
longer, more comfortably.
HOW Through specifically engineered carbon
layups, we tune our Sirrus forks for the
appropriate level of compliance to soak
up vibrations from the road—vibrations
that would otherwise cause rider fatigue.
WHAT Viscoelastic dampers integrated
into the Sirrus fork.
WHY Absorbs road vibration to minimize fatigue
and create a more comfortable ride.
HOW Vibrations travel from the road through the
wheels and up through the frame. Putting
dampers at the mid-section of each fork leg
helps dissolve vibrations as they travel up
the fork, before they reach the rider’s hands
Internal Cable Routing
WHAT Cables contained internally rather
than on the outside of the frame.
WHY Maintains clean design lines and keeps
cables tucked away from the elements.
HOW Cables are routed through the top tube via
cable housing guides brazed into the frame.
