The Shimano FC-4700 [paid link] Crankset is a popular choice among road cyclists, known for its durable construction and reliable performance. However, as with any piece of cycling equipment, cyclists often look to upgrade their components to achieve higher performance, reduce weight, or enhance their riding experience. If you’re considering upgrading your Shimano FC-4700 [paid link] Crankset, it’s essential to understand its compatibility with other components, potential performance enhancements, and best practices for a smooth and successful upgrade.
Understanding the Shimano FC-4700 Crankset
The Shimano FC-4700 [paid link] is a 10-speed crankset in the 105 series, designed for road cycling enthusiasts who prioritize both performance and affordability. It features Shimano’s Hollowtech II technology, which improves stiffness and reduces weight, and it is compatible with Shimano’s 10-speed road bike drivetrains. Before proceeding with an upgrade, it’s crucial to understand what makes this crankset tick and the options available to you.
Key Features:
- Hollowtech II Design: Lightweight, stiff, and durable.
- Double Chainring Setup: 50/34T or 52/36T options for varying gearing needs.
- 10-Speed Compatibility: Optimized for Shimano 10-speed drivetrains, with a broad range of gearing to tackle various terrains.
- Shimano 105 Level [paid link]: Mid-range performance with an excellent price-to-performance ratio.
Is Upgrading the Shimano FC-4700 Crankset Possible?
Upgrading the FC-4700 crankset is entirely feasible, but several factors must be considered to ensure compatibility and improved performance. If you want to explore a lighter, more efficient crankset or switch to an 11-speed setup, you may need to consider replacing more than just the crankset itself. Here’s what you need to know about compatibility and the upgrade process.
Compatibility Considerations
- Bottom Bracket Compatibility:
The Shimano FC-4700 uses the Hollowtech II bottom bracket system, which is a standard for Shimano road cranksets. This system provides excellent stiffness and ease of installation. If you’re upgrading to a new crankset from Shimano’s higher-end models, like the FC-R8000 [paid link] or FC-R9100 [paid link], you will most likely be able to reuse the existing bottom bracket, assuming it’s in good condition and compatible with the new crankset’s design. - Drivetrain Compatibility:
One of the most important aspects to consider when upgrading the FC-4700 crankset is your drivetrain compatibility. The FC-4700 is designed for 10-speed systems, so upgrading to an 11-speed or 12-speed drivetrain would require more than just a crankset swap. You’d need to ensure that your cassette, chain, and rear derailleur are all compatible with the new system. For instance, if you’re upgrading to a Shimano 11-speed crankset (like the FC-R8000 [paid link]), you’d need to switch to an 11-speed cassette and chain. - Chainring Options:
The FC-4700 crankset comes with a double chainring setup, offering gearing ratios such as 50/34T or 52/36T. If you’re aiming for a more aggressive or lighter setup, you may want to consider upgrading the chainrings. Shimano’s newer models, like the FC-R7000 [paid link], offer better performance in terms of weight and shifting precision. Keep in mind that chainring sizes can affect your gear ratios, so choose accordingly based on your riding style and terrain. - Pedal Compatibility:
The Shimano FC-4700 uses a standard 9/16” pedal thread, which is compatible with most road bike pedals on the market. If you are upgrading to a new crankset, you can typically reuse your existing pedals unless you’re looking for performance-specific pedals like Shimano’s SPD-SL or Look pedals.
Best Practices for Upgrading Your Shimano FC-4700 Crankset
Upgrading your Shimano FC-4700 crankset can provide significant performance gains, but to ensure a smooth and trouble-free upgrade, follow these best practices:
1. Assess the Condition of Your Current Components
Before replacing your crankset, check the condition of other drivetrain components. The chain, cassette, bottom bracket, and derailleur play an integral role in the overall performance of your bike. If these components are worn out, it may be more cost-effective to replace them alongside your crankset to avoid compatibility issues.
2. Choose a Compatible Crankset
When upgrading from the FC-4700, Shimano offers several options within its road bike crankset range, such as the FC-R7000 [paid link] or FC-R8000 [paid link]. Both are compatible with 11-speed systems, offering improved performance, lighter weight, and enhanced stiffness. However, if you prefer to stick with a 10-speed drivetrain, you could opt for a high-end Shimano 105 crankset or Ultegra crankset, which maintains compatibility with the FC-4700 bottom bracket.
3. Upgrade the Bottom Bracket (If Necessary)
While the Hollowtech II system is widely compatible with Shimano’s road cranksets, if you decide to switch to a higher-end crankset, you may need to upgrade your bottom bracket. Models like the Shimano BB-R60 or BB-R91 provide excellent stiffness and efficiency. Always ensure that the bottom bracket you choose matches the specifications of your new crankset.
4. Consider a Chainring Swap
If you opt to keep your FC-4700 crankset and simply upgrade the chainrings, you’ll have several options for more performance-focused gear ratios. Shimano’s 10-speed compatible chainrings, such as the 50/34T or 52/36T, will work well with the FC-4700. Alternatively, for lighter setups, carbon fiber chainrings are available, although these come at a premium price.
5. Recheck Your Gear Ratios
A crankset upgrade is an opportunity to optimize your gearing for specific riding conditions. If you’re targeting faster sprints or tackling steeper climbs, consider switching to a higher or lower gear ratio. Higher-end models may offer options like 53/39T or compact 34T chainrings for more aggressive gear setups.
6. Maintain Proper Torque Settings
When installing a new crankset, always adhere to Shimano’s recommended torque specifications for crank arm bolts and bottom bracket cups. Over-tightening or under-tightening these components can lead to poor performance or damage.
Final Thoughts on Upgrading the Shimano FC-4700 Crankset
Upgrading the Shimano FC-4700 crankset is a great way to enhance your bike’s performance. Whether you’re aiming for a lighter setup, improved shifting precision, or compatibility with an 11-speed drivetrain, understanding the key components and best practices is essential for a successful upgrade. By choosing a compatible crankset, ensuring drivetrain coherence, and properly installing the new components, you can significantly improve your road bike’s performance and longevity. Always ensure your upgrade aligns with your riding style and goals for the best results.
