Review FULL SPEED AHEAD Crankset 170mm 11/12-speed 46/30t Direct Mount/90mm Black

The Ahead Wide 336-0375BJ3870 Crankset is a high-performance component designed for modern road bikes, engineered to deliver efficient power transfer and a wide range of gearing options for 11-speed and 12-speed drivetrains.

This crankset comes with a length of 170mm, making it suitable for most riders, and is available in a compact double chainring configuration with a mounting type of 90mm. The compact chainrings have tooth counts of 46 and 30, providing a good balance between climbing and cruising gears.

The crankset's arms are manufactured using Hollowtech II technology, which ensures a lightweight and stiff construction. The hollow design reduces the weight while maintaining strength, and the IsoZone technology integrated into the crank arms helps to absorb vibrations for a more comfortable riding experience.

The 336-0375BJ3870 Crankset is compatible with 11-speed and 12-speed Shimano and SRAM drivetrains, making it a versatile option for riders using different groupsets. The chainrings are easily interchangeable, allowing for a customizable gearing setup to suit various riding styles and terrains.

This crankset also features a 110 BCD (Bolt Circle Diameter) chainring pattern, ensuring optimal chain engagement and efficient power transfer. The crankset is equipped with a 30mm spindle, providing enhanced stiffness and stability to the pedaling platform.

The Ahead Wide 336-0375BJ3870 Crankset is a high-quality component, designed with attention to detail and engineered to provide smooth, reliable, and efficient performance. Whether you're tackling steep climbs or cruising on the flats, this crankset is the ideal solution for riders seeking a versatile and high-performance component for their modern road bike.

The Shimano 105 R7000 5500 crankset with model number 336-0375BJ3870, featuring a 170mm length, 11/12-speed compatibility, and a 46/30T chainring setup with 90mm BCD (bolt circle diameter), is a popular choice among cyclists due to its balance of performance and affordability. Let's examine the pros and cons of purchasing this crankset.

1. Reliability and Durability: Shimano is a well-known brand in the cycling industry, and their cranksets are renowned for their durability. The 105 series components are often considered an excellent value, offering a blend of performance and affordability.

2. Compatibility: This crankset is compatible with a wide range of Shimano 11/12-speed drivetrains, making it a versatile choice for various build options.

3. Chainring Size: The 46/30T chainring setup provides a good balance between climbing and sprinting capabilities. The larger 46T chainring facilitates easier pedaling on flats and climbs, while the smaller 30T chainring aids in higher cadence efforts during sprints or on steep descents.

4. Smooth Power Transfer: The Hollowtech II design of this crankset ensures efficient power transfer from the pedals to the crankarms, resulting in a more responsive and effective riding experience.

5. Affordable: Compared to other higher-end cranksets, the Shimano 105 R7000 5500 is relatively affordable, making it an attractive option for budget-conscious cyclists.

1. Weight: The Shimano 105 R7000 5500 crankset is heavier than some of its more expensive counterparts, which may be a concern for competitive riders or those prioritizing weight reduction.

2. Limited Customization: While the 46/30T chainring setup is suitable for many riders, those with specific gearing requirements may prefer a different setup. This crankset does not offer the same level of customization found in some higher-end options.

3. Potential for Creaking: Some users have reported occasional creaking from the crankset, which can be a nuisance and affect the overall riding experience. Proper installation, maintenance, and the use of compatible bottom brackets can help mitigate this issue.

The Shimano 105 R7000 5500 crankset (336-0375BJ3870) is a reliable and durable component that offers a good balance between performance and affordability. Its compatibility with a wide range of Shimano 11/12-speed drivetrains and the 46/30T chainring setup make it a versatile choice for various build options. Although it has some drawbacks, such as weight and limited customization, the advantages of this crankset often outweigh the cons for most cyclists. If you're looking for a dependable, affordable crankset for your bike build, the Shimano 105 R7000 5500 is an excellent choice.
