This upgrade kit is called the Sustain, and it consists of Wolf Tooth’s proven ReMote lever, a length of housing, a shift cable and a plunger assembly, which threads into the base of the Reverb to actuate the post.
So why would you want to replace the Reverb’s hydraulic line with a shift cable? Many mountain bikers have a love/hate relationship with the RockShox Reverb. They love it when it’s working, and hate it when it needs service, which seems to happen more often than it should.
Many of these issues boil down to user error or a bad bleed from the factory. If you’d rather not mess with bleeding the hydraulic hose, or if you want to make your bike easier to travel with, the Sustain might be right for you.

In addition to making the Reverb more user- and travel-friendly, Wolf Tooth claims the Sustain kit decreases the in-frame length of the Reverb by 40mm when compared to Reverbs that use the RockShox quick-release Connectamajig coupling. This decreased length could be a boon for riders who want to use longer-travel droppers but need a bit more clearance inside their frames.
The Sustain kit uses a version of Wolf Tooth’s ReMote lever designed specifically for the Reverb. Like Wolf Tooth’s other dropper levers, it’s available with a 22.2mm handlebar mount, SRAM’s Matchmaker and Shimano I-Spec direct-mount variants.

The Sustain comes in versions to work with the latest generation of the Reverb as well as the older, but not original, Reverb. The official designations are ‘Reverb B’ and ‘Reverb A2’, respectively.
This kit will not work with externally-routed (non-Stealth) Reverbs or the original A1 version, which is identified by a silver return speed adjuster.
The current, Reverb B dropper post can be identified by the RockShox logo at the top of the slider. The A2 Reverb can be identified by a black return speed adjuster.
Here’s the complete rundown of the installation.
The Wolf Tooth Sustain kit is available now. Pricing is set at $90-100/£70-77/AU$112-125, depending on the version.
