The Shimano FD-5700 [paid link] front derailleur, part of the 105 5700 series, was designed to deliver smooth, reliable front shifting for 10-speed road drivetrains. While it is an older generation component, it remains popular among cyclists who value its durability and precise performance. Correct installation is critical to achieving crisp and consistent shifting, and riders often debate whether to install the FD-5700 [paid link] themselves or seek professional help. This guide explains the entire process, comparing DIY installation with professional service, and helps you decide the best approach for your bike.
Tools Required
- 5 mm hex wrench
- Cable cutters
- Torque wrench [paid link] with a 5 mm bit
- Phillips screwdriver
- Bike stand [paid link] (recommended)
Understanding the FD-5700 Front Derailleur
The Shimano FD-5700 [paid link] front derailleur was designed for road bikes running double chainrings and a 10-speed cassette. It comes in both braze-on and clamp-band versions, making it adaptable to various frame types. The component relies on precise alignment, correct cable tension, and proper limit screw adjustment to deliver clean shifts across the chainrings.
The FD-5700 uses Shimano’s Wide Link design, which improves stiffness and reduces flex during shifts. However, the same design requires accurate set-up to avoid chain rub and misalignment.
DIY Installation of the Shimano FD-5700
Installing the FD-5700 at home is entirely possible if you have the correct tools, patience, and some technical knowledge. The process involves several detailed steps:
Positioning and Mounting
The derailleur cage must sit 1–3 mm above the large chainring, and its outer plate should be parallel to the chainring surface. Incorrect positioning is one of the most common DIY mistakes and leads to noisy or sluggish shifting.
Securing the Derailleur
Using a torque wrench [paid link] ensures that the derailleur clamp (or braze-on bolt) is tightened to Shimano’s recommended torque specification of 5–7 Nm. Over-tightening can damage the frame, while under-tightening can cause derailleur movement under load.
Cable Installation
When routing the front derailleur cable, ensure it passes cleanly under the pinch bolt washer. Proper pre-stretching of the cable reduces the need for frequent readjustments.
Limit Screw Adjustment
The low-limit screw sets the inward travel of the derailleur cage, preventing the chain from dropping inside the small chainring. The high-limit screw controls outward movement, stopping the chain from overshooting the large ring. Precise adjustments are vital for avoiding dropped chains or chain rub.
Fine-Tuning Cable Tension
Shifting performance depends on accurate cable tension. Too little tension leads to hesitant upshifts, while too much can cause overshifting. Fine-tuning can be achieved using the barrel adjuster on the downtube shifter or inline adjuster if installed.
Professional Installation of the Shimano FD-5700
Professional bike mechanics bring experience and precision that can be hard to match at home. In a workshop setting, mechanics rely on specialized tools, calibrated torque wrenches, and years of practice to achieve exact alignment.
A professional installation typically includes:
- Inspection of the bottom bracket and chainline for compatibility.
- Cleaning and preparing the frame contact area before mounting.
- Measuring chain length and confirming chainring compatibility.
- Checking cable housing condition and replacing if necessary.
- Applying professional-grade lubricants and ensuring smooth cable pull.
- Performing a full drivetrain check to synchronize front and rear shifting.
Professionals can also identify potential frame or component compatibility issues, such as mismatched clamp diameter or cross-compatibility with modern Shimano 11-speed systems, which may not be obvious to DIY mechanics.
Common DIY Mistakes with FD-5700 Installation
Several recurring issues arise when cyclists install the Shimano FD-5700 themselves:
- Setting the derailleur cage too high above the chainring.
- Misaligning the cage so it is not parallel with the chainring.
- Incorrect torque on the clamp bolt, leading to slipping or frame damage.
- Over-tightening or under-tightening limit screws.
- Failing to pre-stretch and correctly tension the cable.
These mistakes can cause chain rub, sluggish shifting, or even dropped chains during rides.
When DIY Installation Makes Sense
DIY installation is a good choice if:
- You already own the required tools.
- You have prior experience adjusting derailleurs.
- You enjoy the process of learning and fine-tuning.
- You want to save on workshop labor costs.
With careful attention to Shimano’s specifications and a methodical approach, most riders can achieve a good result. However, it requires patience and a willingness to test and adjust multiple times.
When to Choose Professional Installation
Professional service is recommended if:
- You are unfamiliar with derailleur adjustment principles.
- You lack access to the correct tools, especially a torque wrench [paid link].
- Your drivetrain shows signs of wear, such as stretched cables or worn chainrings, and needs expert evaluation.
- You rely on your bike for racing or long-distance events where flawless shifting is essential.
Professional mechanics can ensure the derailleur is perfectly aligned, cables are properly routed, and the entire drivetrain operates at peak efficiency.
Conclusion
The Shimano FD-5700 front derailleur can be installed successfully at home if you have the tools, patience, and knowledge to follow precise steps. However, professional installation provides accuracy, reliability, and peace of mind, especially for cyclists who prioritize performance or ride in demanding conditions. Ultimately, the decision between DIY and professional installation depends on your mechanical confidence and the level [paid link] of performance you expect from your bike.
