NEAR NET SPV MOLDING Weve taken our revolutionary Near Net dual-molding manufacturing process, that utilizes both silicone and polystyrene internal cores to support the frame shape while it is being pressurized within the steel mold, and added a vacuum purge procedure before molding that compresses and eliminates all air between carbon plies. Compaction is absolutely optimized. Not only is weight reduced while stiffness and strength are increased, but over-reliance on fragile and harsh-riding super-high modulus fiber is minimized. The result is lighter, faster, stiffer, stronger frame that simply rides better. A dual-molding manufacturing process that yields near perfect compaction and eliminates fiber wash and wrinkles during the molding process.
TAPERED, TRI-OVIAL TUBING PROFILES The top and down tubes of the Xenith frame are tapered and tri-ovalized for optimal stiffness in the lightest possible package. This tubing design orients the axis of each of the ovals to increase lateral and torsional stiffness while optimizing vertical compliance in the precise location it is needed.
RIDE TUNED SEATSTAYS Having direct-mount/dual-pivot calipers bolted to the chainstays frees the seatstays from their traditional role of brake system reinforcement. So we can focus on designing and tuning the seatstays for their primary purpose: ride compliance and torsional stability.
SST FOR THE RIGHT RIDE Size specific tubing optimizes ride quality and assures the lightest possible weight for each frame size. SST engineering applies not only to the main frame â€“ our 56, 58 and 61cm frames are designed with top and down tubes 10% larger than on the 44 â€“ 54cm -- but to the seat stays as well. The result is a bike that handles precisely, accelerates explosively and offers compliance for EVERY rider.
DIRECT MOUNT BRAKE SYSTEM Shimanos direct mount/dual-pivot calipers are mounted on the chainstays of all Xenith models and reside symmetrically over the wheel, with arm placement closer to the rim. When coupled with equal cable pull on each side of the rim, modulation is increased significantly. We include an inline QR so wheel changes are no sweat.
WEVE ACEED IT Every 2016 Xenith is equipped with our Adaptive Cable Entry (ACE) system that allows our frames to cleanly manage the internal routing of brake and derailleur cables or electronic Di2 wiring. Xenith models specified with standard cable-actuated drivetrains will be outfitted with ACE plates with integrated cable stops. But we also include with every bike an extra set of ACE plates for Di2 wiring should you ever wish to make the jump to electronic shifting.
BB386 EVO SHELL The BB386 EVO bottom bracket design amplifies the benefits of the proven BB30 system. It takes the lighter, stiffer 30mm alloy spindle from the BB30 design, incorporates press-fit bearing cups instead of direct-fit bearings and marries both to a wider 86.5mm BB shell. All without changing Q-factor. Why a wider shell? It allows us to increase the diameter of our seat and down tubes at the BB shell a full 30%, for increased stiffness where you really need it. We can also optimize chainstay design with an increased diameter that doesnt crowd the rear tire.
ASYMMETRICAL CHAINSTAYS Chainstay design is critical for the efficient transfer of power from pedal to wheel. But simply beefing up the entire area to prevent frame flex under pedaling torque can yield unnecessary weight gain and stiffness. The Xenith chainstay design maximizes stiffness while minimizing weight through asymmetrical design - the driveside chainstay is 15% larger and 30% stiffer to offset drivetrain induced flex.
