An STI shifter designed for road bikes

The ST-4700 is based on the STI ( Shimano) system, with braking and gear-changing functions integrated into the right-hand lever.

This design allows the cyclist to change gears without having to move their hands down to the bottom of the handlebars. The operation is particularly well-suited to road cycling, where changes in pace and gradient require frequent adjustments to the gear ratio.

The right-hand shifter is linked to the rear derailleur, whilst the left-hand shifter normally controls the front derailleur.

Compatible with the Tiagra 4700 10-speed drivetrain

The Tiagra 4700 series is a 10-speed Shimano, with shifter ergonomics inspired by the higher-end Shimano groupsets.

The ST-4700 right-hand shifter is therefore designed for a drivetrain using the rear derailleur and cassette corresponding to this generation.

When replacing a component, it is recommended that you check the part number on your current shifter or groupset to avoid any incompatibility with a different Tiagra generation.

Be aware of the different generations Shimano

Not all 10-speed Shimano shifters are necessarily interchangeable.

The Tiagra 4700 uses a specific cable pull system. It is therefore preferable to replace an ST-4700 shifter with one compatible with the 4700 series, rather than simply choosing a Shimano shifter labelled ‘10-speed’.

A solution for repairing a shift lever

The right-hand shifter can be replaced if it:

• a lever damaged following a fall;
• a worn gear-change mechanism;
• a control that no longer locks gears correctly;
• difficulty selecting certain gears;
• significant cosmetic damage;
• a mechanical fault with the STI mechanism.

Replacing just the shifter allows the other components of the Tiagra groupset to be retained provided they are still in good condition.

Right-hand shifter: rear derailleur

On a traditional road bike Shimano, the right-hand shifter is linked to the rear derailleur.

It therefore allows you to select the different gears on the rear cassette. The number of available positions corresponds to a 10-speed drivetrain.

To ensure optimal performance after replacement, it is advisable to also check:

• the condition of the derailleur cable;
• the cable housing;
• the alignment of the derailleur hanger;
• the adjustment of the limit stops;
• the indexing of the rear derailleur.

A new control cable will not be able to compensate for a heavily worn cable housing or a bent derailleur hanger.

In summary

Shimano ’s Tiagra ST-4700 10-speed right-hand lever (IST4700RI2 ) is a mechanical STI shifter designed for road bikes fitted with the Tiagra 4700 groupset. It controls both braking and rear gear changes, with an ergonomic design suited to road handlebars.

It is a particularly useful part for replacing a damaged or worn Tiagra 4700 right-hand shifter, whilst retaining the rest of the groupset.
