Forward Exit Barrel Adjuster

The Ratio Forward Exit Barrel Adjuster is a direct replacement for the adjuster found in our 1×12 Wide Upgrade Kit – Forward Exit.

Designed to be used with SRAM*’s 1×11 or 1×12 MTB derailleurs. This lets you adjust indexing at the derailleur so it can be combined with a road shifter.

SKU: 0043 Category:

The Ratio Forward Exit Barrel Adjuster is a direct replacement for the adjuster found in our 1×12 Wide Upgrade Kit – Forward Exit.

Now featuring an M6x0.75mm thread with 8 indexing steps per rotation, giving you fine adjustment of ~0.1mm per click. Thanks to the increased diameter, our new adjuster is significantly more sturdy than the Jagwire adjuster originally included in our Forward Exit kit.

The adjuster is designed to be a tight sliding fit into SRAM*’s 1×11 or 1×12 Eagle MTB derailleurs, allowing you to perform indexing adjustment at the derailleur. This is necessary when combining these derailleurs with road shifters which do not have built in indexing adjustment.


This adjuster consists of:

CNC machined aluminium base and screw, manufactured by Ratio #madeinthelakes

MJF 3D printed nylon grip



In your kit you will find:

  1. Ratio Forward Exit Barrel Adjuster

To use the barrel adjuster you will need:

  1. SRAM* 1×11 or 1×12 MTB derailleur


All Forward Exit Upgrade Kits shipped since January 2023 include this new #madeinthelakes adjuster.
