Ready to roll and dressed to kill, the SIRRUS thrives on getting you there fast, and in comfortable style. Its GO! GO! GO! attitude comes courtesy of the road-inspired, lightweight alloy and carbon frames, making it a prime candidate for beat-the-traffic commutes and heart-starting, weekend rides. This fit is dialed and ready, right out of the box, so there’s really only one way to ride this versatile beast—flat out.
WHAT High-performing, experience-specific drivetrains that evolve through the line.
WHY To create high-quality, durable drivetrains that provide the most efficient, intuitive, and smoothest experience for the rider at each level–with an emphasis on wide gear ranges.
HOW BASE New 8-speed Altus triple drivetrain for maximum efficiency for varied terrain and usage, with a 28x32 climbing configuration to make even the steepest hills rideable. SPORT/ELITE Shimano 9-speed triple drivetrains offer renowned performance and loads of gears, plus upgraded cranksets with replaceable chainrings makes maintenance easier. COMP/EXP/PRO/LTD For the ultimate in light weight and fast, accurate shifting we’ve upgrade our higher-end Sirrus models with 2x10 drivetrains. For ins-tance, working with SRAM we developed configurations for the Comp (34/48 x 11-36) equal to triples without sacrificing precision, stiffness, or weight. And Expert, Pro, and LTD models have road bike gearing (34/50 x 11-32), plus high-end 2-piece cranks with integrated BB and external bearings—further increasing torsional stiffness for improved acceler-ation and climbing efficiency.
all-new E5 alloy Frame
WHAT Completely redesigned E5 alloy frames and carbon forks with Zertz featuring smooth welds, tapered/integrated headset, internal cable routing, wide tire clearance, and double eyelet rack/fender mounts.
WHY To improve speed and handling while also boosting style and utility to align better with the riders’ needs—from the Elite level through Pro.
HOW Ultralight E5 alloy frame includes features borrowed from our high-end Specialized models: Precision internal cable routing is quicker to install, eliminates cable rattle, and offers superior shifting and braking performance by keeping grit and grime away from the cables in any weather. The tapered head tube plus a carbon fork with Zertz (also in seatstays on Pro) improve frontend stiffness for better handling and minimize road vibrations. Smooth welds give
the E5 frame a sleek, pro look, while
features like double eyelet dropouts make installing fenders and racks fast and easy without modifications, and extra-wide wheel clearance fits up to
35c tires (32c with fenders).
BG TARGA GRIPS & SADDLES
WHAT New Body Geometry ergonomic
grips (with built-in bar ends) and saddles designed to work perfectly with Sirrus.
WHY To optimize comfort at these key
contact points, while increasing efficiency in the fitness riding experience.
HOW Ample padding and patented BG design assure maximum blood flow to sensitive areas, plus hollow Cr-Mo rails for lightweight support and durability. Targa grips use triple-density rubber
to maximize grip in key areas, and give
a secure connection with the bar, and a contoured profile offers additional wrist support for better blood flow. Plus, they integrate seamlessly with the Targa bar ends which offer riders a more forward position when needed for power or comfort.
FITNESS GEOMETRY W/ DIALED
WHAT Newly designed, flat bar-specific
geos with lower standover, slacker seat
tube angle, and longer reach.
WHY To create the most efficient and comfortable fitness-riding position right out of the box, for a wider range of riders, without major adjustments or swapping components.
HOW Working directly with our BG Fit professors, we straightened the top-tube and made the reach longer. This provides the confidence and stability
of a lower standover while allowing the arms and shoulders to loosen in a more ergonomic position on the bars. At the same time we slackened the seat tube to better align the knee over the pedal, increasing efficiency and comfort while pedaling. The geos are now more aligned with our mountain geos.
