SHIMANO 105 5703 10-Speed Chainring - 39T 130mm BCD

Breathe new life into your trusted road bike with the genuine SHIMANO 105 5703 Chainring. Specifically engineered for 10-speed triple cranksets, this replacement part restores the crisp, reliable shifting performance that the 105 series is renowned for. This high-quality chain blade for Shimano 10 speed cranksets is the perfect solution for replacing a worn or damaged middle ring, ensuring your drivetrain operates with factory precision for many more miles of enjoyable road cycling.

Restore Peak Shifting Performance

Experience the immediate benefit of renewed shifting accuracy and speed. Over time, chainring teeth wear down, leading to slower shifts, chain slippage, and decreased efficiency. Installing a new, genuine Shimano 105 5703 chainring brings back the immediate and decisive chain engagement you expect. The precisely engineered tooth profiles and shift ramps are designed to work in perfect harmony with your Shimano 10s chain, guiding it smoothly and quickly between gears, even under pedaling load. This means more confidence on climbs and faster reactions in a group ride.

Engineered for Durability and Efficiency

As a core component of the celebrated Shimano 105 groupset, this chainring is built to endure the demands of dedicated road cycling. It offers an exceptional balance of lightweight design and robust rigidity, ensuring that every watt of power you produce is transferred directly to the drivetrain without flex or energy loss. Trust in the Shimano legacy of quality to provide thousands of miles of reliable service, maintaining its performance characteristics through changing weather conditions and long training sessions. This 39-tooth ring is the workhorse of a triple setup, ideal for maintaining cadence on rolling terrain and tackling moderate climbs.

Seamless Integration with Your Drivetrain

This chainring is designed specifically for the 5-arm, 130 mm BCD (Bolt Circle Diameter) standard used on the FC-5703 triple crankset. This guarantees a perfect fit and optimal alignment, which is critical for flawless front derailleur function and minimizing chain noise. By using a genuine Shimano component, you ensure complete system compatibility within your 10-speed drivetrain, from the shifter to the chain to the cassette. Don´t compromise your bike´s performance with generic parts; choose the component engineered to work as part of a complete, integrated system.
