The Shimano FC-6700 [paid link] chainring, part of the 105 series, is a highly regarded component known for its reliability, smooth shifting, and performance. However, as with many cyclists looking to enhance their rides, upgrading parts like the chainring is a common pursuit. In this guide, we’ll explore whether upgrading the Shimano FC-6700 [paid link] chainring is possible, how to do it properly, and the best practices to ensure compatibility with your existing drivetrain setup.
Understanding the Shimano FC-6700 Chainring
Before considering any upgrades, it’s important to understand the key features of the Shimano FC-6700 [paid link] chainring. This component is designed for road bikes, with a focus on durability and high performance. It’s part of Shimano’s 105 series, a mid-range offering that balances quality with cost. The FC-6700 is available in various tooth counts to match different riding styles, whether you’re climbing steep hills or cruising on flat terrain.
The FC-6700 chainring is made of aluminum alloy and features a 4-bolt attachment system, making it relatively easy to swap out or replace. It’s designed to work with Shimano’s 10-speed road drivetrains, providing smooth and precise shifting, which is crucial for consistent performance.
Can You Upgrade the Shimano FC-6700 Chainring?
Upgrading your Shimano FC-6700 chainring is possible, but there are a few things to consider before making any changes. The first thing to determine is whether your current drivetrain is compatible with the new chainring you want to install. Shimano’s 105 series components are compatible with various other Shimano groupsets, but certain upgrades, such as swapping to a different series or a 11-speed drivetrain, may require additional parts.
Key Compatibility Considerations:
- Drivetrain Compatibility: The FC-6700 chainring is designed for a 10-speed drivetrain. If you’re looking to upgrade to an 11-speed setup, you’ll need to ensure that the chainring is compatible with the 11-speed chain and shifting system. Shimano 11-speed drivetrains typically require a different chainring design, and while some FC-6700 chainrings are interchangeable with 11-speed setups, it’s crucial to check the specifications before purchasing.
- Crankset Compatibility: The FC-6700 chainring uses Shimano’s 4-bolt crankset attachment system. If you’re planning on upgrading to a different crankset (for example, a Dura-Ace or Ultegra model), ensure that the new chainring is compatible with your existing crankset. Shimano’s 4-bolt pattern is fairly standard, but not all models share the same bolt circle diameter (BCD). It’s essential to verify that the new chainring will fit the BCD of your crankset.
- Tooth Count and Chainring Size: Shimano FC-6700 chainrings come in different sizes, typically ranging from 34T to 53T for the outer ring and 30T to 39T for the inner ring. If you’re considering a performance upgrade, you might opt for a larger or smaller chainring based on your riding style. A larger chainring might be better for fast, flat rides, while a smaller one may benefit climbers. However, when changing the size, you must ensure your front derailleur can accommodate the new range of motion.
Best Practices for Upgrading Your FC-6700 Chainring
When upgrading the Shimano FC-6700 chainring, follow these best practices to ensure compatibility and maintain optimal performance:
1. Verify Compatibility with Your Existing Components
Ensure that the chainring you’re upgrading to is compatible with the rest of your drivetrain. This includes checking the BCD (bolt circle diameter), chain compatibility, and whether your front derailleur can accommodate the size of the new chainring.
2. Choose a Chainring from a Compatible Series
When upgrading, consider sticking with a Shimano chainring from the same or a similar series, such as the Shimano 105, Ultegra, or Dura-Ace. Using a different brand or series may cause shifting issues and decrease performance due to differences in chainring tooth profiles and designs.
3. Double-Check Crankset and Chainring Sizes
Ensure the new chainring size matches your needs and is compatible with your crankset. Also, make sure that the chainring teeth count suits your riding style. Switching from a compact to a standard chainring, or vice versa, can change your gear ratios and affect how your bike performs on different terrains.
4. Replace the Chain and Cassette if Necessary
If you’re upgrading the chainring to one designed for a different drivetrain (such as moving from 10-speed to 11-speed), you will likely need to replace your chain and possibly your cassette as well. A mismatched chain and cassette can cause poor shifting performance and premature wear.
5. Install with Precision
When installing the new chainring, ensure the bolts are tightened to the manufacturer’s recommended torque settings. This helps prevent issues like slipping or uneven wear. It’s also a good idea to use a torque wrench [paid link] to ensure accuracy. Clean the crankset and chainring interface thoroughly before installation to avoid grit and dirt that could damage the components.
6. Fine-Tune Your Front Derailleur
After installing the new chainring, fine-tune the front derailleur to ensure it shifts smoothly between the chainrings. The height, limit screws, and indexing may need adjustment to accommodate the new size of the chainring, especially if you’ve chosen a larger or smaller one.
7. Test and Break-in Your New Chainring
After installation, it’s important to test your new chainring by riding in different gears and conditions. The break-in period allows the chainring to settle, and you can make any necessary adjustments to your front derailleur or shifting system to ensure everything runs smoothly.
Conclusion
Upgrading your Shimano FC-6700 chainring can enhance your bike’s performance, but careful consideration is necessary to ensure compatibility with your existing components. By following the steps outlined in this guide and choosing the right parts, you can upgrade your chainring to maximize your bike’s efficiency and overall riding experience. Always remember to install and adjust your new chainring with precision to achieve the best results.
