Building the Best Bike for Time Trials: A Deep Dive into the Factor Hanzo

The saying “records are made to be broken” fueled a five-year aspiration to challenge place-to-place cycling records. Despite years of contemplation, the push to actually attempt these records only came after an unexpected setback: a broken leg in December 2021. This injury, while unfortunate, became the catalyst. Recovery became intertwined with a new goal – not just healing, but building the ultimate machine to conquer these records. The biggest hurdle, surprisingly, wasn’t physical fitness, but the lack of a truly optimized time trial bike.

2022 transformed into a dual project: rehabilitation and the meticulous creation of the best bike possible for record attempts. This article is the latest installment in our “building the best bike for” series, detailing the components and rationale behind what we consider a near-perfect setup for tackling time trial challenges.

Ultimately, the year culminated in attempts at three records. One was broken, another narrowly missed, and the third didn’t even reach the starting line, highlighting the unpredictable nature of record attempts and the crucial role of equipment.

This particular “best bike” build differs slightly from previous iterations in this series. While earlier builds focused on specific events or demands, a time trial bike aimed at endurance records necessitates greater adaptability. Courses vary, durations stretch, and the relentless march of aerodynamic technology means today’s cutting-edge innovation might be superseded tomorrow. Therefore, consider this not the definitive “best bike” for time trialing, but rather a highly refined configuration within an ever-evolving quest for speed.

At the core of any exceptional bike build lies the frame. For record attempts spanning diverse distances and terrains, the chosen frame needed to be more than just aerodynamic; it required significant adjustability. The Factor Hanzo emerged as the ideal candidate. Its design is a masterclass in modern time trial technology: an incredibly narrow and deep head tube, truncated airfoil tubing, an external fork steerer seamlessly integrated with a mono riser front end, widely set fork legs, dropped seat stays, and the stopping power of disc brakes. The Hanzo embodies a comprehensive approach to aerodynamic efficiency and rider adaptability.

With the frame selected, the focus shifted to optimizing the front end for maximum watt savings. Time trial extensions have undergone a revolution since Greg LeMond’s iconic 1989 Tour de France victory. Modern “skis” not only facilitate a more aerodynamic rider position but also integrate with the rider’s arms, refining the overall aero profile and distributing forearm pressure. Elbow rests have evolved into supportive structures, enabling riders to contort themselves into incredibly aerodynamic shapes. The Wattshop Anemoi extensions embody these advancements, exuding speed even at a standstill.

Adaptability remained paramount for various events and distances. The Hanzo fork and Factor base plate combination create a mono-riser system. While intended for a cut-to-length steerer, removing the top cap allows for a vast range of front-end height adjustments, accommodating both aggressive and more relaxed positions. Wattshop angled risers offer precise and straightforward micro-angle adjustments for the aero extensions, ranging from 5 to 25 degrees. These anodized 7075-T6 aluminum risers not only tilt the extensions but also neatly channel Di2 wires through the risers and into the Factor base plate, maintaining a clean aesthetic and aerodynamic advantage.

Completing the Wattshop front end are the Anemoi carbon arm rests. Their high-sided design offers superior support, enhanced comfort, and improved aerodynamic integration with the rider’s arms compared to traditional open armrests. The high sides provide a bracing point, aiding in maintaining a compact and aerodynamic position for extended periods.

This data-driven approach ensures the best equipment setup for specific conditions and courses.

Deep rim or tri-spoke? Why not both? The Princeton Carbon Works Mach 7580 TS front wheel is a 75/80 mm deep sinusoidal rim tri-spoke marvel. It features a 20.5mm hook-to-hook tire bed, a 27mm external width, and a proprietary integrated one-piece aerodynamic axle. This dream time trial wheel, however, comes at a premium, with a price tag of $2,750 – and that’s just for one front wheel, as noted on Princeton’s product page.

For the rear wheel, the new Black Inc Zero disc, specifically designed to complement the Hanzo frame, was selected. This asymmetrical disc features a lenticular shape and a drive-side only “virtual 100mm” rim, claimed to provide up to 20 watts of “thrust”. Flipping to the non-drive side, the disc exhibits a bulbous lenticular shape, engineered for substantial aerodynamic gains. This asymmetrical design is dictated by the space constraints of the drivetrain on the drive side, resulting in a unique and visually striking appearance.

Fast wheels demand fast tires. Up front, the 25mm Continental GP 5000 TT TDF tire was chosen, offering enhanced aerodynamics and reduced rolling resistance. It’s further optimized with a Silca speed shield for the most marginal of gains.

Hydration is essential, but aerodynamics are paramount. A stash of Elite Chrono CX aero bottles and cages, originally acquired for an ultra-race, integrates seamlessly with the Hanzo downtube. For non-UCI events, a Camelbak under the skinsuit remains an option, but integrated bottle solutions are preferred for their aerodynamic benefits.

Wove V8 TT saddle on the Factor Hanzo, designed for comfort and aero position maintenanceWove V8 TT saddle on the Factor Hanzo, designed for comfort and aero position maintenance

Time trial bike comfort is relative; a degree of discomfort is often accepted as a consequence of aerodynamic positioning. Shifting, sliding, and numbness were once considered inevitable. The Wove V8 TT saddle aims to challenge this notion. Colorado-based Wove claims the V8 “will change how you feel about being in the aerobars.” This 140-gram carbon saddle is designed to minimize thigh rubbing and soft tissue pressure in the aero position, while a high-grip material helps riders maintain their position without resorting to extreme measures.

The nose of the V8 saddle is longer and narrower than typical TT saddles, while the rear retains sufficient width for riding in an upright position. Rear bottle cage mounts offer the option to carry additional hydration or potentially gain further aerodynamic advantages by smoothing airflow off the rider’s back.

Speaking of aerodynamic adaptations to standard components, the CeramicSpeed OSPW Aero system is arguably the most debated component on this build. Depending on rider position, this aerodynamic pulley system is either a gift from the time trialing gods, incorporating the efficiency gains of oversized pulley wheels without the associated aero drag penalty, or simply another set of derailleur pulleys. For this build, we firmly lean towards the “time trialing gods gift” perspective.
