We love dropper posts. The trail riders in the bunch love 'em for their practical use, the mechanics in the bunch love exploring the way the different models work. Our engineer guy Aaron (AKA Dutch-E) is both. The remotes for dropper posts, however, leave much to be desired in most cases: awkward placement, funky actuation--not terribly human in design. For that reason, we really like the Specialized SLR Lever for their Command Post as it mates to our favorite SRAM brakes via the MatchMaker OR to Shimano brakes via our own MisMatch Adapter. That doesn't help us with other dropper post models, so Dutch-E made his own. This is some next-level hacking, so if you care deeply about the condition of your front shifter, look no further.
Gotta pop the screws out of the bottom of your second-favorite SRAM left-hand shifter.
Take a picture will you? It's impossible to remember how this stuff all fits back together. This took something like eight attempts to reassemble. The spring comes out so you can access the rest of the internals.
The arrows here are identifying the "indexing finger." Theres one of these on 2x shifters, two on 3x systems. They all gotta go. This is because you need the cable to pull and release on each lever push.
Now we've got to get the indexing plate out of there so we can grind off that finger. 5mm hex wrench and S2 square drive bit.
Now we've got that little sonofagun out of there, we file off the finger. Use a bench grinder if you're feeling lucky.
There's a bunch more steps if you click here.
