BMC Timemachine Road vs others
Giant Propel Advanced
The Giant Propel Advanced is an aero road bike designed for speed.
At first glance, it’s evident that this bike is fast and stiff with its slim frontal end and deep-dish wheels. All Giant Propel models are disc-only and have hidden cables for a clean aero profile.
The Giant Propel Advanced SL is the lightest among them, with an integrated seat post, and uses Giant’s highest-grade carbon fiber, the Advanced SL. The Advanced is one step down and heavier due to the different carbon fiber used and non-integrated seat posts.
| Model | Frame material | Groupset | Wheelset | Retail price (USD) |
|---|---|---|---|---|
| Giant Propel Advanced SL | Advanced SL carbon | Shimano Dura-Ace Di2 (R9200) | CADEX 50 | $12,500 |
| Giant Propel Advanced Pro 0 | Advanced carbon | Shimano Ultegra Di2 (R8100) | Giant SLR 1 50 | $8,000 |
| Giant Propel Advanced Pro 0 AXS | Advanced carbon | SRAM Force eTap AXS | Giant SLR 1 50 | $8,000 |
| Giant Propel Advanced 1 | Advanced carbon | SRAM Rival eTap AXS | Giant SLR 2 50 | $6,000 |

BMC vs Giant carbon fiber
BMC ACE+
The BMC ACE+ (Accelerated Composites Evolution Technology +) is the latest carbon fiber layup technology used on all BMC road bikes.
ACE+ operates by determining the cross-sections of the frame, the arrangement of the carbon layers, and the geometric structure based on targeted performance values. Subsequently, it generates thousands of virtual models to pinpoint the ideal equilibrium of performance, focusing on three fundamental aspects; Stiffness, Weight, and Compliance.
BMC has two different carbon grades, 01 Premium Carbon and Premium Carbon, in their road bike frames. The choice between the two carbon grades depends on the rider’s preferences, budget, and desired level of performance.
- 01 Premium Carbon is a high-grade carbon fiber material with superior performance, stiffness, and weight savings. It provides enhanced ride quality with improved power transfer and responsiveness. Premium 01 carbon is used on all BMC models with 01, such as Teammachine SLR01 and Roadmachine 01.
- Premium Carbon is a mid-range carbon fiber material that balances performance, weight, and affordability. It is used on all BMC models without the 01.
Giant Advanced Composite Carbon
Giant’s Advanced Composite Carbon is a proprietary carbon fiber technology used in constructing bicycle frames. It’s a high-quality composite material with carbon fibers embedded in a resin matrix.
Using Advanced Composite Carbon, Giant can design frames with specific performance characteristics tailored to different riding disciplines. The material offers excellent vibration-damping properties, enhancing comfort and reducing fatigue on long rides. It also provides efficient power transfer, enabling riders to maximize their pedaling efficiency and accelerate easily.
The Giant Advanced Composite Carbon is available in standard and SL (Super Light) versions.
- Advanced SL represents the pinnacle of Giant’s carbon fiber engineering and construction. Advanced SL frames undergo additional optimization, utilizing a higher grade of carbon fiber and meticulous layup techniques. It’s found in Giant’s top-of-the-line bikes.
- Advanced is a step down from the top-tier Advanced SL carbon fiber, but it still offers an impressive balance of performance and value for money.
Frameset technologies and innovations
BMC Timemachine Road and Giant Propel Advanced framesets incorporate advanced technologies to enhance their bikes’ performance and ride characteristics.
Here’s an overview of the technologies used in each bike model.
BMC Timemachine Road 01
| Name | Description |
|---|---|
| Accelerated Composites Evolution Plus (ACE+) | ACE+ utilizes advanced computer algorithms and simulation techniques to optimize the layup and design of carbon fiber frames and components. With BMC ACE+, engineers can explore various design possibilities and fine-tune the carbon layup to achieve specific performance objectives. This technology allows precise control over stiffness, compliance, weight, and aerodynamics. ACE+ enables BMC to create frames that offer optimal balance and performance characteristics by analyzing numerous virtual prototypes and conducting virtual testing. |
| Aerocore Design System | An advanced aerodynamic design approach used by BMC to optimize the aerodynamic performance of their road bikes. It is a holistic system that integrates multiple bike elements, including frame shapes, tube profiles, component integration, and overall bike geometry, to minimize aerodynamic drag and maximize efficiency. |
| Integrated Cockpit System (ICS) | Seamlessly integrates the handlebar, stem, and fork to improve aerodynamics, enhance stiffness, and provide a clean, integrated look. The elimination of external cables reduces drag and improves handling responsiveness. |
| Tuned Compliance Concept (TCC) | TCC optimizes vertical compliance by strategically tuning the carbon layup and tube shapes. This technology improves the frame’s ability to absorb road vibrations and bumps, resulting in a smoother and more comfortable ride without sacrificing performance or power transfer. |
Giant Propel Advanced
| Name | Description |
|---|---|
| Advanced Composite Technology | Utilizes Giant’s High Performance Grade raw carbon material and Modified Monocoque Construction technique to create a custom frame material. This carbon composite offers a high stiffness-to-weight ratio, balancing lightweight performance and strength. |
| OverDrive Aero | Incorporates a D-shaped fork steerer tube and internal cable routing for an extremely aerodynamic system. The design reduces air drag and provides an efficient, sleek profile. The internal cable routing enhances the bike’s overall aesthetics and ease of maintenance. |
| Vector Integrated Seatpost | Features an integrated seatpost design that saves weight compared to standard composite posts. This aerodynamic seatpost adds compliance, improving rider comfort and reducing road vibrations for a smoother ride. |
| PowerCore | Incorporates a massively oversized bottom bracket/chainstay area with a fully integrated 86mm wide bottom bracket design (92mm wide for off-road bikes). The asymmetrical chainstays provide additional stiffness on the drive side and stability on the non-drive side, ensuring efficient power transfer and precise handling. |
| AeroSystem Shaping Technology | Utilizes Computational Fluid Dynamics (CFD) and wind-tunnel data to optimize each tube shape for superior aerodynamic performance. The precise shaping reduces air drag and increases the bike’s efficiency, allowing riders to achieve higher speeds with less effort. |
