The cable-killer: SRAM AXS wireless shifting

By Spencer Powlison

I made a big step this week: I went down to the local bike non-profit, Community Cycles, and donated my stash of shifter cables and housing that I’d been jealously hoarding for decades.

I have fully committed to the cable-free lifestyle.

Why, you might ask, did I do away with all of these useful spare parts? These consumables could come in handy, right? That used to be true, but now my mountain bike has a SRAM Eagle AXS drivetrain, my gravel bike has SRAM Force AXS, and my road bike has SRAM eTap — all electronic, wireless ways to shift a bike drivetrain.

By now, the traditionalists in the crowd might be dismayed. How could he? And only a few weeks after Eddy Merckx’s birthday! For shame.

I’m not here to convince you to give up cable-actuated shifting. The majority of the time, it works great. It needs occasional maintenance. Nothing’s perfect; such is life. Instead, I’m going to run you through the most notable ways this cable-free fleet has changed my day-to-day life as a bike rider.

Maybe it’ll sound amazing to you, and you’ll consider buying a SRAM AXS group of your own — that’s up to you (and your budget).

Five things I do with SRAM AXS

Shifting a SRAM Force AXS lever
1. Shift more often

My coworker Bruce asked me if I shift more often now that I use electronic drivetrains. It took me a minute to reflect on my habits. That’s a good thing. It meant to me that I’d gotten so used to the ease of shifting action that I didn’t spare much time thinking about it. And upon reflection, I think I do change gears more often. I am quick to pop back and forth between cogs when I’m not totally happy with my cadence. I love using the multi-shift function which lets me simply hold down the button and jump several cogs at once. Apart from Campagnolo road parts, no cable-actuated shifting system lets you dump multiple gears in both directions (usually it’s just downshifting). That feature is huge for abrupt changes in terrain, especially on trails.

2. Check my batteries

This habit is not necessarily a “pro” that counts in favor of AXS or any electronic shifting. I am careful to check my bike’s batteries, especially before long rides. The good news is that it’s as simple as pressing the AXS button on my derailleurs. If the light is green, I’m good to go. If it’s red or blinking red, I just click in a fresh battery that I keep on a charging station. For peace of mind, I bring a spare battery on epic days (like my trip to Kansas). I’ve never needed to do a mid-ride change on my gravel bike. On my mountain bike, I occasionally swap my dropper post battery with my derailleur battery if I see my shifting charge is getting low. Now that I have a Force AXS drivetrain on my gravel bike, I have noticed that the front derailleur battery runs out quicker than the rear. I’ve been told that front derailleurs require more power to shift the chain, which makes sense to me.

3. Connect with the AXS app

I wouldn’t say that I wanted my bike to have a smartphone app, but I’ve gotten used to it, and SRAM’s AXS app is really user-friendly. When I was setting up my mountain bike’s AXS, I couldn’t decide on how to configure the shifter buttons. No worries, I pulled out my phone on the trail and switched things around until I got it where I liked it. Also, if you want to go full-on techy, you can use the app to set up TireWiz pressure sensors on your valves, which I did with Zipp’s 3ZeroMoto wheels on my mountain bike. Finally, SRAM’s been developing its AXS web platform to collect ride data based on your drivetrain’s activity on any given ride. Unfortunately, it only works with Garmin so far, and I’m a Wahoo man. Hopefully, soon I’ll be able to view some of those insights about shifting patterns and more.

4. Display gearing on my head unit

It’s not necessarily hard to look down to see what gear you’re in, but it is objectively easier to see a visual display on your head unit. This feature isn’t limited to AXS components — any electronic groupset will let you see your gearing on most GPS devices. But it’s just one of those little features that I can’t live without.

5. Easily swap drivetrains

OK, this is not a typical thing that most riders will have the luxury of considering. However, if you’re running a “mullet” drivetrain (single-chainring Eagle AXS shifting) on your gravel bike, and you feel like swapping to Force AXS with a double, it’s pretty painless. I know because I did this on my Lauf True Grit gravel bike. Internal cable routing? Forget about it. Shifter compatibility? Easy, just pair the clickers to your new derailleurs. No need to re-wrap bar tape or route brake lines.

Three things I don’t do with SRAM AXS

1. Worry about mud, dirt, dust, or water

Now, growing up as a mountain biker in New England, I wouldn’t say I ever truly “worried” about bad conditions. But, now I don’t have to worry about the consequences. There are no cables or housing to get fouled up (remember my parts stash I just gave away?). The shifting won’t degrade during a muddy race. And I know that firsthand, having suffered through a wet 50-mile day at the True Grit mountain bike race. My Eagle AXS was trouble-free and shifting fine.

2. Finesse front shifting

Even though front derailleur and chainring designs have come a long way, a well-executed front shift always requires a little finesse on a bike with cables. Once I got accustomed to tapping both shift buttons simultaneously to move the front derailleur, I could jam my chain into the big ring with little concern.

3. Readjust my shifting

While you have to set up AXS components precisely, once they’re adjusted, they’re adjusted for life. Cable stretch won’t impact shifting performance. Grubby housing won’t lead to finicky upshifts. Also, if you swap wheels, you can easily fine-tune the rear derailleur's indexing with the shifter buttons. They're like wireless, electronic barrel adjusters!

  • I run the Eagle AXS on my Hightower and would say that the one downside is the nagging fear of ripping off the rear derailleur (and the concomitant cost of replacement).

  • Funny you say that, Todd! I was actually fibbing a little in this story… I do still have my vintage ‘86 Centurion which has cable-actuated downtube shifting. Indeed, I almost ride that bike like a singlespeed, whereas I’m always shifting my AXS bike. That said, you could do a pretty rad retro-mod with rim-brake AXS parts and an old-school steel frame…

  • Your point about shifting more often, effortlessly, unconsciously is a great one. There has to be a calculation on how much more efficient one rides because of e-shifting. I’ve been racing since 1981 so I went from downtube to shift lever (which felt like the greatest invention in the world) to Di2 and I’m amazed how great it’s all gotten.
