Product Details

Overview & Technology

SRAM 4mm Inline Adjusters (Model ID: AC-MGT-CBL-A1, MPN 00.7915.052.030) are compact barrel-style cable adjusters designed specifically to work with 4mm cable housing. Supplied as a pack of two, these inline adjusters let you fine-tune cable tension quickly and accurately without tools — ideal for field tweaks and on-the-trail tensioning. Built for everyday reliability, these adjusters feature a precision-machined metal body with a corrosion-resistant finish for long life in wet and muddy conditions. Their threaded barrel mechanism gives smooth, incremental adjustment so you can compensate for cable stretch, housing compression, or seasonal brake pad wear with micro-adjustments that keep shifting crisp and braking consistent.

Key Features

Simple, effective design: The inline barrel adjusts cable tension by altering housing length behind the adjuster — a fast way to remove play or increase cable pull without disassembling the system. The adjusters accept standard 4mm housing sleeves and slide onto the housing like other inline barrels. Real-world benefits include quick on-trail tweaks after new cable stretch, easy adjustment for riders who swap tires or rims, and improved control when small tension differences affect pad contact or derailleur indexing. Sold as a pair (Qty 2) so you can fit both front and rear or keep a spare in the toolbox.

Fit & Compatibility

These inline adjusters are engineered for use with 4mm cable housing and pair naturally with SRAM cable systems, but they also work with other brands that use 4mm housing and standard barrel stops. They’re intended for cable-actuated systems — mechanical brakes and derailleurs — where a 4mm housing core is used. Because they are a simple inline barrel, installation is universal: slide the adjuster onto the 4mm housing, seat it into the cable stop or noodle as required, and thread the barrel to achieve the desired tension. Confirm the adjuster body fits your frame’s cable routing and that there’s enough threaded engagement for secure adjustment.

Who It's For

These adjusters are perfect for mountain bikers who value easy, dependable cable control — from trail riders tuning brakes between descents to mechanics building bikes who want a compact, durable adjuster option. They’re also great for commuters and home mechanics who need a reliable spare part to keep bikes shifting and braking well. If you ride frequently in mixed conditions, swap components often, or prefer mechanical systems that require occasional tension tweaks, the SRAM 4mm Inline Adjusters are a low-cost upgrade that improves day-to-day adjustability and long-term cable performance.

Frequently Asked Questions

Will these inline adjusters fit 5mm housing?

No. These adjusters are sized for 4mm cable housing and will not properly accept 5mm housing. For 5mm systems look for adjusters specifically designed for that larger diameter to ensure secure fit and reliable adjustment.

Can I use these on both brakes and derailleurs?

Yes — they work with any cable-actuated system that uses 4mm housing. That includes many mechanical rim brakes, V-brakes, and some shift setups. Always verify your bike's housing diameter before fitting.

How do I install and adjust an inline barrel?

Slide the adjuster onto the 4mm housing, insert the housing into the cable stop or noodle, and thread the barrel to increase or decrease tension. Lock the cable in place and make small turns while testing function until indexing or pad contact is correct.

Are these compatible with non-SRAM frames and components?

Yes. The adjusters use a standard inline barrel form factor for 4mm housing, so they are generally compatible with components and frames from other manufacturers that take 4mm housings and standard barrel stops.

How long do inline adjusters last?

With quality construction and normal use they last for years, but service life depends on exposure to elements and frequency of use. Replace if the threads feel rough, the barrel binds, or corrosion prevents smooth adjustment.

Buying Guide

When buying inline adjusters, match the adjuster diameter to your cable housing size — these are specifically for 4mm systems. Consider buying a pack of two so you can fit both front and rear circuits or keep a spare in your tool roll. Look for durable metal construction and corrosion-resistant finishes if you ride in wet or muddy conditions. For frequent on-trail adjustments, choose an adjuster with smooth threads that won’t bind after repeated use.
