​@SRAM's electronic Eagle AXS derailleur and RockShox Reverb AXS dropper post are as fancy as can be. Do they work better though? What's rad and what could be improved? Join Vital MTB Product Editor, Brandon Turman, for a deep dive into the world of wireless shifting, dropper posts, and his long-term impressions.

There is no denying that these are luxury components and completely unnecessary to have fun on your bike, but man are they cool.

Overall, SRAM AXS works well as a system, combining wireless technology that is both reliable and nearly instantaneous to make things easier, faster, and a more natural extension of your body in many ways. You barely tap the controllers and the result is a more accurate shift or dropper adjustment. There are also fewer cables, which is sweet, and the potential for trickle-down is exciting.

For those who love data and devices, AXS is a dream thanks to AXS Web and various integration abilities. For those who don't, it's possible to use the system without thinking twice about it. While there are many conveniences when it comes to AXS, there are tradeoffs when it comes to dealing with batteries and apps.

After this test, the full AXS setup is going onto a new trail bike. I find that rides on the Transition Patrol are most often straight up, straight down, and after a year of riding it, I think the precision the AXS system offers – whether it's shifting under load or finding that perfect seat height – is much more fitting for a trail or cross-country bike where you see a lot of rolling terrain.

As for the Reverb AXS, is this the dropper perfected? It definitely seems like it.
