A Robo-Neutrino with SRAM Force eTap

by Igor

When Brook from SRAM emailed us asking about getting a Neutrino, I was incredibly intrigued. Is this a personal commuter? Traveler? Are they coming out with mini-velo components? Turns out, they wanted a fun and approachable bike to showcase their new eTap AXS Wireless Force components both at their booth and seminar for Philly Bike Expo. Enter Robo-Neutrino...


The idea is that while SRAM often shows these items on high-zoot mountain and road bikes, they haven't really told folks about the benefits and flexibility of the wireless platform on a bike that will see more practical urban use. While I cannot speak to the long term reliability (I'm sure it's good), the performance and ergonomics of the system is really fantastic.


The rocker button is in a perfect place for your thumb, leaving plenty of room for your hand on the grip. Additionally, the shifter can tell the derailleur to dump gears up and down simply by holding the respective button. It's pretty neat.


On the left side side sits the remote dropper lever. It's just a button. Press it once while sitting on the saddle and the post goes down. Press it again and the post goes up. It's a nice speed too. Putting a dropper on the Neutrino makes the bike that much smaller when space is at a premium. 



It also had a Force crankset and SRAM Hubs.


Stopping is handled by their Level Hydraulic Brakeset. It stopped those tiny wheels with ease and comfort.


The part that brings the whole kit together is Sram's controller app for your phone. You can program all the buttons, monitor component readiness, update firmware, and personalize component behavior. It's all pretty trick.


What do you think of this Robo-Neutrino? Whether it's Mavic Zap, SRAM eTap, Campy EPS, Shimano Di2, or otherwise, have you tried electronic shifting?

The only real benefit I can see is that the 10T cogs allow a more normal sized chainwheel to get a reasonable high gear. However, the road AXS chains have a different sized roller so apparently only the matching rings will work, and these top out at 50T...

I'll bet you would sell a bunch of these as completes. Any idea what the price would be?

Does anyone else feel all the electronic hype is getting out of hand considering the ethical issues surrounding the labor in mining and manufacturing, let alone electronics waste? I appreciate that e-bikes and electronic shifting platforms help those with certain physical conditions start and/or continue riding, but am concerned that to some extent these things are mostly just another wave of marketing-induced consumption exacerbating some of humanity's global problems.

No, nobody else thinks that. We're not going to stop building things with electronics.

I volunteer for an organization that provides bikes for people with disabilities. Some of this technology would be quite helpful to people who have little to no use of their fingers. Motor assist tech is also helpful. But for those of us who are lucky enough to have no disability; it seems like the answer to a question which no-one asked. How much delay do you experience when shifting with conventional equipment? And, by the way, what happens if you forget to charge the system or a wire breaks? This electronic technology is simply "the next big thing" which probably will be "yesterday's news" in another couple of years. By then, the manufacturers will have moved on to implanted devices which allow you to think a shift. Good for the manufacturers; just a money pit for the rest of us.

While electronic shifting may be over-hyped, e-bikes are not. Last summer, Madison, Wisconsin, converted its entire bike share fleet to electric bikes. Ridership more than doubled. Getting people off the couch and out of their cars is a step toward addressing, not exacerbating, some of humanity's global problems.

That little electronic shifter on the Neutrino may eventually help me keep riding. I have basal joint arthritis predominantly in my right hand and have moved my rear shifters to the left side. Realistically this disease isn't going to stay only in the right, which means shifting with manual pressure may become impossible for me. I'm glad we have electronics available to solve this.

This will evolve and find a good use. But, it is an example of technology overwhelming simplicity. The simple bicycle with simple moving parts and simple to service is not so much any more.

Mixed feelings. My Prius makes a good comparison. Many benefits from reduced carbon footprint, but the increased electronics in cars can be a money pit. The motherboard in my car has gone out, so the dash and camera displays don't work now - that's a thousand dollar fix. A more analog car has dials for the dash information, not a motherboard, and those dials are just super reliable. This little electronic shifter is a great idea (especially for the physically challenged) but it's a lot more expensive than a mechanical shifter to repair, may require more specialized servicing as opposed to owner repair (cars all get hooked up to computers now at major cost). Is that the direction we are going with bikes, which are currently affordable means of transportation? Are these devices just for the elites who can afford them? I think e-bikes are great for lots of people, I even have a small drive for my bike but it's the only part of my bike I cannot service myself. I used to be able to work on and fix my car myself, too. And then there's all the batteries and the pollution from producing this stuff, sigh.

After a few years of modernity:
- I returned to the BB square pin: low costs and zero maintenance;
- I'm back at 2x9 speed: the chain consumes less and costs little;
- I returned to the friction bar-end: excellent and reliable.

Joseph, nobody else thinks what, exactly? I didn't propose, and would not propose, the complete end of manufacturing or developing new electronics. Come at me when you care about nuance.

Mad Mike, likewise, I didn't propose an end to electronic bikes. You and I may perhaps be thinking about different global problems, though. I come from the most privileged land in the world, so also would prefer people off their office chairs, automobile seats, etc for the sake of their own health (I worry about my mother's bank-job weight, for instance), but that's not the type of global problem I was talking about. Instead, I was referring to the global problems experienced by those outside of my fellow citizens' sedentary, lazy, complacent lifestyles, specifically those of laborers which allow we citizens as much - those upheld not only by electronic bicycle systems of today, but also by bicycle manufacturing of yesterday.

I still support people getting out of their cars, out of their work chairs, etc. I just prefer to do it by mechanical, more affordable bicycles, something many of my e-bike interested customers haven't even considered (maybe because money/advertisement dictates inordinate amounts of social thought).

So I'll end by encouraging people to think about political turmoil around the world, such as the recent military coup in Bolivia, a country that has suffered under corporate subjugation over water in decades past, but most recently over lithium. Your rechargeable batteries (something I begrudgingly sell in bicycle lights) generally come from someone else's loss. If you care about your rights, please make sure the products you order come from systems securing the rights of those who make those products.

Thanks for reading, folks.
