Upgrading your crankset can significantly enhance your bike’s performance, but it’s essential to understand the compatibility factors that affect the Shimano FC-5700 [paid link] crankset. In this guide, we will dive into the various considerations for upgrading your FC-5700 [paid link], including compatibility with other components, best practices for installation, and how to optimize its performance to get the most out of your ride.
Understanding the Shimano FC-5700 Crankset
The Shimano FC-5700 [paid link] crankset is part of Shimano’s 105 series, which is designed for road cyclists who seek a high-performance component at an affordable price. It is made of aluminum alloy, featuring Shimano’s HollowTech II design, which combines lightweight construction with durability. The FC-5700 crankset is designed for 10-speed drivetrains, with an emphasis on smooth shifting and power transfer.
Before you consider upgrading, it’s crucial to understand the specific features of the FC-5700 and what parts may need to be replaced to achieve optimal performance. Let’s explore the different compatibility factors you should consider before upgrading.
Crankset Compatibility with Other Drivetrain Components
One of the most significant factors when upgrading a crankset is ensuring compatibility with your current drivetrain. Here are the key components you need to assess:
Bottom Bracket Compatibility
The Shimano FC-5700 crankset uses the HollowTech II technology, meaning it requires a HollowTech II bottom bracket. This bottom bracket design features an integrated spindle and uses external bearings to ensure smooth rotation.
When upgrading, you must ensure that the bottom bracket matches your bike’s frame. If you’re switching from a different crankset type, you may need to replace your bottom bracket to accommodate the new one. Shimano offers several versions of the HollowTech II bottom bracket, so be sure to select the one that fits your frame type (e.g., BSA, PressFit).
Chainring Compatibility
The Shimano FC-5700 crankset is typically equipped with 50/34T compact chainrings, but there are other chainring options available for this model. If you’re upgrading, you may want to switch to different gearing, such as a 53/39T or other combinations depending on your riding style and terrain.
However, upgrading the chainrings requires careful attention to the crankset’s bolt pattern. The Shimano FC-5700 uses a 110mm BCD (Bolt Circle Diameter) for its chainrings, so make sure any replacement rings have the same BCD and are designed for 10-speed drivetrains.
Derailleur Compatibility
The Shimano FC-5700 crankset is designed for use with Shimano’s 10-speed road derailleurs. If you’re planning to upgrade to a newer 11-speed or 12-speed drivetrain, you’ll need to check whether your current derailleur will still function smoothly with the upgraded crankset.
Generally, when upgrading to a higher-speed drivetrain, you must replace the front derailleur to ensure proper shifting performance. For example, a Shimano 105 11-speed front derailleur may work well with a new 11-speed crankset, but you will need to ensure that the front derailleur’s pull type (top or bottom) and cage length are compatible.
Chain Compatibility
For an upgrade, you should also check if your current chain is compatible with your new crankset. The Shimano FC-5700 is designed for a 10-speed chain, and upgrading to a 11-speed or 12-speed drivetrain may require a new chain, as these newer models have narrower widths.
Make sure that the chainring and chain are designed for the same number of speeds to ensure smooth and precise shifting. It’s important to replace the chain as part of the upgrade process to maintain optimal performance.
Best Practices for Upgrading Your Shimano FC-5700 Crankset
When upgrading your Shimano FC-5700 crankset, follow these best practices to ensure the installation is done correctly and that the performance of your bike is optimized:
1. Choose Compatible Parts
Before purchasing replacement parts, ensure they are fully compatible with the Shimano FC-5700 crankset and other components of your drivetrain. Always check the bottom bracket type, chainring BCD, and the number of speeds (10-speed, 11-speed, etc.) to ensure proper compatibility.
2. Use Professional Tools
While some riders may attempt to perform a crankset upgrade on their own, using the correct tools is crucial to avoid damaging the components. A crankset installation tool, bottom bracket tool [paid link], torque wrench [paid link], and a chain tool are essential for ensuring proper installation and adjustment. These tools will also help you achieve the proper torque settings for each component.
3. Properly Torque Crankset Bolts
It is important to apply the correct torque when tightening the crankset bolts. Over-tightening can cause damage to the crank arms, while under-tightening can lead to crank arm slippage or instability. Refer to Shimano’s recommended torque settings, which typically range from 30 to 40Nm for the crank arm bolts, and use a torque wrench [paid link] for accuracy.
4. Check for Chainring Wear
Before upgrading, inspect your chainrings for any signs of wear, such as worn teeth or excessive play. If the chainrings are worn out, replacing them with a new set will ensure smoother shifting and better power transfer. If you’re upgrading your chainrings, ensure that they are designed for the same number of speeds as your drivetrain.
5. Install the New Bottom Bracket
When replacing the crankset, it’s often best to replace the bottom bracket at the same time. This ensures that your crankset will rotate smoothly and that the bearings in the bottom bracket are not worn out. Make sure the bottom bracket is installed with the correct orientation and that the threads are properly greased to prevent creaking or water ingress.
6. Test the Setup Before Riding
After installing your upgraded crankset, take the time to test your setup before going for a ride. Shift through all the gears and check for any issues with the front derailleur, chainring alignment, or bottom bracket. Pay attention to any noises or resistance that might indicate an issue, such as a loose crankset, improper chainring alignment, or an incompatible bottom bracket.
Conclusion: Is Upgrading Your Shimano FC-5700 Crankset Worth It?
Upgrading your Shimano FC-5700 crankset can improve your bike’s performance, but it’s essential to understand the compatibility and installation requirements before making any changes. By selecting compatible parts, ensuring proper installation, and paying attention to the details, you can maximize your upgrade and enhance your riding experience.
If you’re considering an upgrade, assess your current drivetrain, choose the right components, and follow best practices for installation to ensure a seamless transition to your new setup. With the right upgrades, your Shimano FC-5700 crankset can offer years of smooth, efficient performance.
