Stay Ahead of Time

The new Timemachine Disc is the ultimate triathlon machine, the most refined expression of pure aerodynamic performance featuring cut-ting-edge disc brake technology. It is a bike designed for progressive triathletes seeking the perfect synthesis of drag-defying aerodynam-ics, sublime handling and world-traveler functionality.

Extended research enabled us to scope out and achieve extraordi-nary aerodynamics through innovative disc brake integration for im-proved handling and a confident ride on the most technically de-manding courses.

A standout feature, the integrated caliper covers optimize airflow as it hits the bike, seamlessly woven into the frame design to achieve the class-leading integration that is the foundation of the Timemachine’s aero prowess.

Along with an extensive rider positioning system and state-of-the-art component integration, the Timemachine Disc is the must-have bike for middle and long-distance triathlons or time trials.

Aerodynamic formThe newly revised SubA concept deploys all of our aerodynamic advantages: 3:1 tubes with truncated profiles, integrated caliper covers, crosswind-stable tube shapes, a hinge-fork design, super lean frontal area and ultimate integration from front to back.

Combined with a refined rider-positioning system, this machine is all about free speed. Long-course triathlons, time trials or solo efforts in wind-swept terrain, there’s no need to go slow.

Dependable handling, unmatched functionalityTimemachine Disc features complete disc brake integration to deliver supe-rior handling and control on the most technical courses without compro-mising its aerodynamic performance.

Disc brakes and thru axles improve functionality during international travel thanks to easy wheel changes and dependable brake-pad positioning.

Dual-purpose, rider-focused fitA lightning-fast frame is a good start – but adding a versatile, aerody-namic positioning system for the rider is what will break records. The Position-to-Perform (P2P) system lets triathletes find their ideal con-tact points without sacrificing aerodynamics, no matter how aggres-sive or conservative their front-end position.

Triathlon needs, prioritizedPrecision engineered for performance, this bike marries compo-sure for crosswinds with speed for the straights, gives welcome versatility and adaptability for reach and stack, plus thru-axles for functionality. In short, it’s a triathlon and time trial bike that shoots and scores for multi-sport performance. If your race includes a bike split, this is the machine for you.

Optimized Airflow

We thoroughly researched the airflows created by calipers and rotors through CFD modeling in order to No dots be-hind every sentence their impact the on aerodynamic performance. We soon re-alized that disc brakes and rotors can greatly impact aerodynamic perfor-mance when no specific solutions are adopted.

Caliper CoversWe designed aerodynamic caliper cov-ers to optimize the airflow around the disc brake calipers and minimize the im-pact on aerodynamic performance.

The result is the aerodynamic perfor-mance of our Timemachine with the ben-efits functional integration of disc brake technology.

The V-Cockpit Because free-speed is the name of the game, the new Timemachine’s frontal profile is a narrow and seamless engineering marvel.

The V-Cockpit offers optimal aerodynamic perfor-mance for taller pad stack dimensions, while the forward-offset promotes vertical compliance, a state-of-the-art blend of high-performance and com-fort.

The fully integrated 3rd generation hinge-fork en-sures a lean frontal profile.

While the cockpit mounting system promotes both form and function.



The Flat-Cockpit A rear-mount equipment storage box, top tube fuel box mounts, and down tube dual-mount bottle cage options add up to a dedicated triathlon weapon.

The Flat-Cockpit offers the maximum aerodynamic advantage, allowing riders the lowest possible pad stack configurations.

Aerodynamic Form

The newly revised SubA concept summarizes our aerodynamic advantages: 3:1 tubes with trun-cated profiles, crosswind-stable tube shapes, hinge-fork design, a super-lean frontal area and maximum integration overall.

Combined with our Position-to-Perform (P2P) rider-position system, this machine is all about free speed - for long course triathlon, time trials or solo efforts in wind-swept terrain.



Form, Function, Fit.Pre-processing / model build-up

Including both the rider and the appro-priate position are critical to real-world aerodynamic performance.

Throughout the study, standard triathlon and time-trial positions are simultane-ously evaluated.

To develop the most accurate Compu-tational Fluid Dynamics (CFD) model, highly precise mesh generation is key. Each intersection of mesh is a point that will be used for measurement.

Due to differences in average speeds in triathlon and time-trial performances, weighting of yaw angles is important to develop accurate, discipline-specific re-sults.

Mesh generation Discipline weighting Rider definition



Form, Function, Fit.Calculations

For each frame tube (eg. headtube, downtube, toptube, seatube, seatpost, seatstays and chainstays) the system generates 16 tube shape variations tested at 9 yaw angles and two rider po-sitions.

By isolating the sub-assemblies, having a refined mesh and an accurate and pre-cise CFD model in operation, the defini-tion of how all components contribute to the system is calculated for headwind (Cx) and crosswind conditions (Cy).

The CFD model is ready, the rider is es-tablished, the environment is set – the new bike begins with a tube shape eval-uation, using all known parameters.

Component contribution Tube shape analysis Tube shape analysis



Form, Function, Fit.Evaluation

Storage impacts overall aerodynamic performance - the rear-mounted stor-age box enhances Cx performance without a sacrifice in Cy, even at ex-treme yaw.

The major goal of the tube shape study was to define the overall best perform-ing combination of shape for Coefficient of Drag in headwind (Cx) and crosswind (Cy) conditions.

Understanding how hydration accesso-ries and their placement affects aerody-namic performance, leads to specific downtube and seatube profiles, with two- position mounting options for the downtube.

Form, Function, Fit.Evaluation

From the tube shape study it was learned that higher arm pad stack con-ditions of most middle and long-course triathletes presented a new chal-lenge.

With taller stack height, the torso and legs are exposed, causing a back-pres-sure and contributing to increased overall drag. Additionally it was observed that a disproportionate amount of turbulent airflow was created.

Engineers and aerodynamicists worked together to formulate a system to minimize these effects – the end result is the patented V-Cockpit. With cleaner air moving rearward and a decreased pressure differential the re-sult is more free speed.

In addition to aerodynamic performance, the forward offset promotes en-hanced vertical compliance – the optimal balance of performance and com-fort.

Rider-focused

A slippery-fast frame is a good start – but adding a versatile, aerody-namic positioning system for the rider breaks records.

The refined Position-to-Perform (P2P) system lets triathletes find their ideal contact points without sacrificing aerodynamics, no matter how aggressive or conservative their frontend position. For riders seeking straightline speed, predictable crosswind stability and industry-leading integration, look no further - this is the bike for races against the clock.
