Time Alpe d'HuezvsScylon

While the Alpe d'Huez sticks to a rim-brake-era 28mm maximum tire clearance, the aero-focused Scylon Gen 2 surprisingly allows for 32mm tires despite its racing intent. These frames differ most in their front-end philosophy, with the Scylon trading the Alpe d'Huez’s traditional 73-degree head tube for a much slacker 71.5-degree angle.

Time Scylon

Overview

The Alpe d'Huez positions itself as a classic mountain tool, whereas the Scylon moves into the high-performance aero space. Both use Time's signature resin-injected carbon socks, but the Alpe d'Huez favors a traditional 27.2mm round seatpost and a leaner frameset weight of 1,260g to favor long-distance comfort and mechanical simplicity. The Scylon Gen 2 uses deeper aero profiles and a proprietary seatpost to target speed on the flats, though it manages to damp vibrations as well as many endurance bikes. Choosing between them often comes down to a price gap of nearly $2,000 for a similar groupset. The Alpe d'Huez offers a boutique, European-made experience that undercuts the price of many mass-produced flagships from larger brands. The Scylon is the flagship superbike for those who want that denser, more connected 'Time feel' without sacrificing the aerodynamic efficiency required for fast group rides and competitive racing.

Ride and handling

The Alpe d'Huez manages to filter road vibration in a way that keeps you fresh, with one long-term rider noting they felt zero hand numbness even after four hours on rough chip-seal. It isn't just about comfort; the bike maintains its composure on deteriorating surfaces where other frames might bounce and lose momentum. Out-of-the-saddle efforts on 10% gradients feel direct and efficient, with a bottom bracket that remains rock solid under heavy torque. Even high-speed descents at 40+ mph feel stable, with reviewers describing the sensation as 'gliding.' Switching to the Scylon reveals a ride that feels surprisingly quiet and nearly insulated from road buzz. A specific reviewer likened the vibration damping to a steel frame with 35mm tires, yet noted 'zero deflection' in the fork during hard braking. This front-end rigidity allows the bike to carve through technical corners with near-perfect modulation, making it feel like an extension of your intent. It doesn't get squirrely when the pace is high, maintaining a smooth, predictable line even when the rider is at their physical limit. The Alpe d'Huez uses a standard 27.2mm seatpost, a detail that adds vertical deflection compared to deeper aero posts. It remains a machine that focuses on tactile feedback and simplicity. Meanwhile, the Scylon uses its proprietary aero seatpost and integrated cockpit compatibility to shave seconds off a solo effort. While the Alpe d'Huez is a climbing specialist that 'earns its name,' the Scylon has a dual personality, surging forward like a heavy aero bike on flats while feeling agile when the road tilts upward.

Specifications

The Scylon demands a significant financial jump, with the SRAM Red E1 AXS build retailing for $11,269—over $1,800 more than the Alpe d'Huez with the same groupset. This premium covers the deeper aero tube profiles and proprietary components, but the Alpe d'Huez offers a compelling value for those who prefer standard interfaces. Across both models, Time uses the PF386 EVO bottom bracket standard, relying on their tight manufacturing tolerances to avoid the creaks common in mass-produced press-fit frames. Wheel options vary between the two models to match their design goals. While both models allow for wheelset choices, Scylon builds frequently feature deeper 60mm Vision Metron rims to complement its aero frame. The Alpe d'Huez is typically paired with 45mm rims like the Vision Metron 45 RS, keeping the rotational weight lower for mountainous terrain. Both models use high-quality finishing touches like Arundel Gecko Grip tape and Selle Italia Novus Boost saddles, though the Scylon often ships with larger 30c tires compared to the 28c spec on the Alpe d'Huez.

Geometry and fit comparison

Fit differences are stark between these two machines. A size M Alpe d'Huez provides a 562mm stack height, which is 13mm higher than the size S Scylon's 549mm. Despite the Scylon being an aero bike, its reach is nearly identical at 382mm versus 383mm on the Alpe d'Huez. This makes the Scylon a significantly lower and more aggressive fit for riders who have the flexibility to stay tucked for hours. The Alpe d'Huez uses a classic 73-degree head tube angle to deliver the sharp, immediate steering expected of a traditional climber. In contrast, the Scylon uses a much slacker 71.5-degree angle, paired with a 50mm fork offset to yield a 62mm trail figure. This combination grants the Scylon a longer 996mm wheelbase on the size Small, favoring a centered, stable feel when moving at high speeds. The Alpe d'Huez, with its shorter 985mm wheelbase and 58mm trail, feels more eager to change direction mid-climb. For riders with longer legs and shorter torsos, the taller stack of the Alpe d'Huez will be easier to live with without a massive stack of spacers. The Scylon is built for the racer who wants to minimize their frontal area. While both share a 73-degree seat tube angle, the Scylon’s proprietary post allows for a range of -20mm to +10mm of setback, giving you more freedom to dial in your position over the bottom bracket compared to the Alpe d'Huez’s standard 27.2mm post.

Who each one is for

Time Alpe d'Huez

If you spend your time hunting vertical gain on poorly maintained backroads and want a bike that won't punish you on the rough, frost-heaved descents that follow, the Alpe d'Huez is the correct choice. It suits the rider who values a 'forever bike' with standard parts and a frame that feels denser and more resonant than mass-market carbon. It’s an ideal partner for a mountainous gran fondo where mechanical reliability and all-day comfort are more important than pure aerodynamic drag.

Time Scylon

For the racer who lives for the intensity of a high-speed group ride or a local criterium, the Scylon provides the necessary edge. It excels in the micro-accelerations required to close a gap or sprint for a town line. If you want the speed of a modern aero superbike but refuse to tolerate a harsh, chattery ride quality, the Scylon’s unique ability to damp vibrations while remaining stiff at the fork makes it a rare breed in the aero category.
