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 – our 56, 58 and 61cm frames are designed with top and down tubes 10% larger than on the 44 – 54cm -- but to the seat stays as well. The result is a bike that handles precisely, accelerates explosively and offers compliance for EVERY rider.
WE ACE'D IT

Every 2017 Xenith is equipped with our new 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.
THE DISC REVOLUTION IS HERE

We are all-in. Disc brake technology provides superior stopping and safer braking no matter the conditions. They offer increased control and better modulation as you vary from being at-speed to slowing down or stopping. They are significantly less affected by rain and wet conditions, and eliminate any rim heat build-up that can come with caliper brakes. Gone is the need to be concerned with carbon rim deformation. Whether the streets of NYC or LA, or long and winding open roads, the control and safety that comes with disc brakes will only heighten the experience that comes with a riding a Jamis.
NEAR NET SPV MOLDING

We’ve 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.
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 and disc brake forces 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.
TAPERED, TRI-OVAL TUPING 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 chainstay-mounted disc brakes frees the seatstays from their traditional role of brakes reinforcement. So we can focus on designing and tuning the seatstays for their primary purpose: ride compliance and torsional stability.
BB386 EVO BB 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 does not crowd the rear tire and allows extra room for a 28C.
MODULAR THRU-AXLE SYSTEM (MTS)

Jamis’ MTS system increases the12mm thru-axle fit-range by offering multiple aluminum inserts designed to accommodate the various threaded thru-axles produced by any number of hub and fork makers.

XENITH SERIES

JAMIS 最高峰のレースモデル、XENITH(ゼニス)は2017年、ディスクブレーキを装備し新たな走りを創造した。これまでいくつもの賞を獲得し、レースでも実証されてきたXENITHの性能ではあったが、JAMISエンジニアは、さらなる高みを求めた。それはただディスクブレーキを搭載するだけではなく、XENI TH全体の再デザイン、全く新しい製法の採用にまで行き着く。そして新デザインのフレームとフォークは、軽さ、剛性、そしてエアロ効果をこれまでにないレベルに高めた最速ロードバイクを創りだした。チーム Jamis-Sutter Homeの勝利を担うマシンである。
