Tiagra is a series of road bike components from Shimano, a leading manufacturer of bicycle parts.
Tiagra 4600 and 4700 are two generations of Tiagra groupsets, which include the shifters, brakes, derailleurs, crankset, cassette, and chain.
As Shimano’s entry-level offering for road cycling, it provides a cost-effective solution without compromising on performance.
However, before making your decision, it’s essential to be aware of certain compatibility issues that could impact your choice.
Shimano Tiagra
Shimano Tiagra has been available since 1999 and has undergone several revisions over the years. The current version is the 4700 series, launched in 2015.
It remains a 10-speed groupset, while Shimano’s higher-end groupsets have moved on to 11-speed or even 12-speed configurations.
Comparison: Tiagra 4600 Vs 4700
Tiagra 4600 was introduced in 2011 as the first 10-speed version of Shimano’s entry-level road groupset.
It was compatible with other 10-speed Shimano groupsets, such as Ultegra 6700 and 105 5700, allowing riders to mix and match parts from different series.
Tiagra 4700, launched in 2015, was an update to Tiagra 4600. It features a new four-arm design for the chainset, offering a lighter and stiffer alternative to the previous five-arm design.
The 4700 series also improved shifting performance and ergonomics, making them more similar to Shimano’s higher-end groupsets.

Compatibility Issues
A crucial aspect to note is that the Tiagra 4700 series is not compatible with the previous 4600 series or any other 10-speed Shimano groupsets like Ultegra 6700 or 105 5700. This is due to the different cable pull ratio used in the 4700 series, which requires matching shifters and derailleurs for smooth and accurate shifting.
Performance and Features
Shimano Tiagra 4700 offers several advantages in terms of performance and features over the 4600 series:
Tiagra 4700 Performance
The 4700 series provides smoother and more precise shifting, particularly beneficial for demanding conditions like gravel roads.
The electronic shifting option (Di2) and the clutch rear derailleur reduce chain slap and drop, enhancing the overall experience.
Tiagra 4700 Features
With a focus on gravel riding, adventure cycling, bikepacking, and cyclocross, Tiagra 4700 boasts a wider gear range, ergonomic brake levers, and gravel-specific derailleurs to minimize chain drop and noise.
Hydraulic disc brakes deliver superior braking power and modulation, and the anti-slip levers offer better grip and comfort.
Tiagra 4600 Performance
Tiagra 4600 offers smooth and precise shifting, well-suited for casual and recreational riders. Its durable components can withstand everyday use, providing reliable performance at an affordable price.
Tiagra 4600 Features
The 4600 series is available in 10-speed versions, with either rim or disc brakes, and can be configured as a 2x or 3x setup. It comes with ergonomic brake levers and provides versatile gearing options for different riding styles.
Price and Value
While Tiagra 4700 offers enhanced features and performance, it does come at a higher price compared to Tiagra 4600.
As an entry-level groupset, Tiagra 4600 remains a more budget-friendly option for those seeking reliable road cycling performance without breaking the bank.

Factors to Consider
When choosing between Tiagra 4600 and Tiagra 4700, consider the following factors:
Budget
If you are on a tight budget, Tiagra 4600 might be the better option as it is more affordable.

Personal Preference
The decision depends on your personal preference and riding goals.
Some cyclists might prefer the simplicity and lightness of a 1x setup, while others may lean towards the versatility and gear range of a 2x or 3x setup.
Hydraulic disc brakes may appeal to those who value excellent braking performance, while others might prioritize the ease of maintenance provided by rim brakes.
