SHIMANO SM-CA70 Inline Cable Tensors / Adjusters (2 Units)

Achieve flawless, on-demand gear shifting and restore precision to your road bike´s drivetrain with the genuine SHIMANO SM-CA70 Inline Cable Adjusters. Sold as a convenient set of two units, these essential spare parts are the perfect solution for cyclists seeking to fine-tune their derailleur performance with ease and accuracy. If you´ve ever been frustrated by hesitant gear changes, chain noise, or the inability to make micro-adjustments during a ride, the SM-CA70 tensors are the definitive upgrade for your bicycle.

Designed for seamless integration, these adjusters mount directly onto the down tube braze-on bosses of compatible road bike frames, providing a clean, professional, and aerodynamic profile. They serve as both a cable stop and a tension adjuster, allowing you to make immediate, precise modifications to your derailleur cable tension without stopping your ride or reaching for tools.

Key Benefits:

* On-the-Fly Shifting Precision: The primary benefit of the SM-CA70 is the ability to make instant, minute adjustments to your gear cable tension while you ride. A simple twist of the ergonomic barrel adjuster can eliminate chain rattle, sharpen gear indexing, and ensure every shift is crisp, quiet, and immediate. This is crucial for competitive riders and enthusiasts who demand peak performance at all times.
* Enhanced Drivetrain Performance: Over time, gear cables can stretch, leading to sloppy and unreliable shifting. Installing these SHIMANO cable adjusters allows you to easily compensate for this stretch, restoring the factory-fresh precision of your front and rear derailleurs. Enjoy a smoother, more responsive, and ultimately more enjoyable cycling experience.
* Clean and Integrated Aesthetics: Specifically engineered for frames with down tube shifter bosses, these adjusters offer a sleek and integrated look that complements the lines of any modern or classic road bike. They replace standard cable stops with a far more functional and elegant component, showcasing a commitment to performance and detail.
* Legendary SHIMANO Durability: As an authentic SHIMANO component, the SM-CA70 is built to last. Manufactured from high-quality aluminium, it offers an excellent balance of low weight and robust strength, ensuring reliable performance and resistance to corrosion through countless miles and varying weather conditions.

Main Features:

* Inline Barrel Adjuster Design: Allows for easy, tool-free rotation to increase or decrease cable tension.
* Down Tube Mounting: Designed to fit standard down tube braze-on bosses for a secure and stable fit.
* Road Derailleur Specific: Optimised for use with the thinner inner cables found on road bike front and rear derailleur systems.
* Complete Set: The package includes two complete adjuster units, one for the front derailleur and one for the rear, providing a total system overhaul.

What our customers are saying about Shimano SM-CA70 cable tensor 2 units

This inline barrel adjuster allows for easy, on-the-fly gear adjustments right from your handlebars. A robust, lightweight, and effective shifter cable tuner, it´s praised for its quality build and reliable performance. Compatible with 4mm derailleur cable housing, its user-friendly design makes fine-tuning gear cable tension simple while pedaling. A good-looking and practical upgrade for precise shifting, especially for Shimano drivetrains. While not the most compact design available, its functionality is excellent

Álvaro

It solved my problem by being able to replace the old original one on my bike that had worn out and was causing the front derailleur to rub because I couldn't tighten the cable.

Quality article at a reasonable price

a basic internally wired bicycle to adjust the bike's shifting from the handlebar.

Handy adjusters

Gert Jan

Work fine. Handy to mount it close to the handlebars, so that you can adjust during the derailleur.

Great product

Jose Figueiredo

Diverter cable tuners, very light, effective, good looking, at a fair price. I strongly recommend it.

Shimano quality, but a little big

2020/06/28

Paulo Alexandre

This product does what is required of it - allows you to adjust the tension of the shifting cable. However, there are more compact solutions on the market, for example from Jagwire. I acquired it once that the transmission is also Shimano and so everything stays the same brand. Easy to use product, the gray color allows to distinguish from the color used by the handlebar, which is normally black, facilitating the discovery for adjustments while driving.
