TRed bikes take {custom} aerodynamics to a brand new rider-individualized degree of their newest X23 Swanigami monitor bike prototype – impressed by such iconic monitor developments just like the Lotus 108, Pinarello Espada, and Graeme Obree’s controversial “Previous Trustworthy”. Combining years of biometric 3D scanning of riders with the newest additive manufacturing applied sciences, TRed’s X2_ monitor bike prototype improvement mission goals to make next-level aerodynamic efficiency tailor-made individually to every bike owner extra attainable…
TRed X23 Swanigami 3D-printed alloy monitor bike prototype
We’ve been watching TRed’s {custom} monitor bike improvement progress quickly over the previous decade. What began with premium custom-fit metal and aluminum monitor bikes that drew consideration – and accolades – at NAHBS within the US, has developed into one thing far more race-focused.
The final evolution we had caught up with was the Peregrine-inspired Falcon, which successfully was the start line for this X2_ prototype improvement mission. Now this X23 is the newest iteration, however in keeping with TRed it’s persevering with to adapt by way of racer suggestions, laptop simulation, wind tunnel improvement, and actual race testing on the monitor.
How does rider-centric aerodynamics make the bike sooner?
Leveraging their {custom} becoming course of that employs a singular 3D-scanning of the rider since 2016, TRed leaned on the truth that a well-fitting monitor bike the place the rider can preserve their optimum aerodynamic place for longer is usually instances the quickest monitor bike.
The rider makes up such a good portion of the aerodynamic drag of a monitor bike, TRed and their manufacturing unit TOOT Racing crew checked out how one can make the rider sooner first, then how one can use that slippery aero rider to make the bike sooner too.
They name the method “digital twins” as they mannequin the digital rider on the bike within the laptop, then examine the information with the precise measurements of the identical rider and actual bike mocked up within the wind tunnel.
This enables them to raised reconcile the advanced and dynamic relationship that’s usually troublesome to precisely estimate in CFD simulation.
TRed says they regarded to the historical past of improvements on the monitor for inspiration, the place after all they came across the slender, ahead positions of Graeme Obree on his distinctive hyperbikes. In addition they observe how most of the most iconic monitor bikes have completed away with the toptube in an effort to cut back drag.
The results of dynamic biometric optimization – first modeled nearly, then refined within the wind tunnel – is a extra aerodynamic rider place. With that established, TRed creates probably the most aerodynamic bike design underneath the rider – figuring on the actual airflow character coming off the rider’s forearms, pushed down off their chest, and flowing off the rising & falling movement of the racer’s legs whereas pedaling.
Whereas religiously decreasing frontal is usually the first concern in decreasing monitor bike drag, TRed’s rider-centric aerodynamic strategy, for instance necessitated transferring the body tubes away from the stress wave coming of the rider’s chest and directing airflow wider off the fork to relive air stress, and finally scale back whole aero drag.
The true bodywork of the binomial bicycle/bike owner is the athlete: he’s the engine and the “fairing” on the identical time and subsequently it have to be designed as a technical half: it should carry out at its greatest from a mechanical viewpoint and work together higher with the elements to optimize aerodynamics.

UCI approval to race, and registered for the Olympics
Now, TRed & Toot are working throughout the confines of extra restrictive present UCI technical design laws, however they’re pushing the envelope with options just like the severely sloping toptube, deep airfoil tube shapes, tubing junction webs, and built-in cockpit.
TRed assures us that the X23 Swanigami body does adjust to UCI guidelines, and will likely be UCI-approved in time for the Argentina nationwide crew and their rider Facundo Lezica to compete on the bike on the upcoming UCI World Championship in Glasgow this summer time, and registered to race the Paris 2024 Olympics subsequent summer time. Some elements just like the custom-made handlebar & aero extensions have already been Olympic-approved and raced within the 2023 Nations Cup.
A 3D-printed aluminum bike in a sea of carbon?
An enormous profit right here is that weight usually isn’t such a defining issue on the monitor, so TRed might work with numerous metals to ship the extra essential stiffness traits needed for tremendous highly effective monitor racers to get probably the most out of their bike. Steel tube shaping had been a limiting issue to optimized aerodynamics in years previous. However identical to we noticed with Pinarello’s 3D-printed Hour Document bike, fashionable additive manufacturing now usually signifies that a steel bike might be simply as fast, and even faster than a carbon bike, with out the lengthy improvement time to create and regulate costly molds.
In the end, many parts of the TRed X23 are created in an R&D partnership with the College of Pavia’s 3D PROTOLAB, then mixed with different solid or CNC-machined alloy components, and even some composite parts.
The additive-manufactured X23 body is primarily constructed of 3D-printed aerospace-grade Scalmalloy scandium aluminum alloy, because of its excessive power:weight ratio. (Nonetheless very a lot hidden right here in razzle dazzle camo.) Different components of the {custom} monitor bike are additionally 3D-printed in titanium or in metal, just like the super-narrow Asheeta 3D handlebar.
Because of using 3D-printed metals from body to cockpit elements (and polymer mockups throughout prototyping), TRed says they will flip round new prototypes in document time, at prices that deliver the fully-customized course of into attain for smaller groups and nationwide federations.
What’s subsequent for the 3D-printed X23 Swanigami & TRed’s X2_ mission?
Formally the X23 is the present iteration of the continuing TRed X2_ monitor improvement mission – TRed even calls it a “first stage”, nonetheless ‘in testing’ on the monitor. Whereas it’s prepared for the Argentinian crew to race internationally, TRed continues to be transferring ahead with optimizing their iterative aerodynamic designs.
However though it’s nonetheless a piece in progress, it’s an open mission, and meant to be each accessible and extra sustainable resulting from its use of resilient, recyclable steel supplies. TRed are at all times interested by new riders and new groups seeking to work collectively on their motorsports-inspired analysis, race, and improvement tasks.
