My Electronic Groupset Review: Campagnolo EPS

Ah, the allure of Campagnolo EPS is indeed strong, with its sleek design and promises of ease. But, ponder this: what of its vulnerability to electronic interference, or the complexities of diagnosing and repairing issues? And as for future updates, might I suggest the ability to adapt to various riding styles, a self-calibrating function, or even integration with biometric data? Food for thought, indeed.

One potential downside to Campagnolo EPS is its limited battery life, which can be a concern for riders who embark on long, multi-day events or epic backcountry adventures. Additionally, the system's reliance on proprietary components and charging infrastructure may make it more difficult to find replacement parts or support when traveling.

Battery life is indeed a crucial factor for many riders, particularly those tackling long tours or remote trails. The reliance on proprietary components raises essential questions about accessibility and support, especially in diverse terrains. How do you see this impacting the overall appeal of Campagnolo EPS for serious cyclists? Would the potential inconvenience of sourcing parts deter riders who might otherwise appreciate its features? Additionally, what strategies could manufacturers explore to enhance battery longevity or improve the support infrastructure while maintaining the system's performance edge? These considerations are vital for a comprehensive evaluation of electronic groupsets in the cycling landscape.

Battery life, the bane of every cyclist's existence, especially during those grueling long tours. And let's not forget about the joy of sourcing proprietary parts in remote terrains! Because who doesn't love a good scavenger hunt while on a cycling adventure?

But hey, maybe we're missing the point. Perhaps the real thrill of Campagnolo EPS is the added challenge of keeping its battery alive and tracking down those exclusive components. After all, what's the fun in riding without a dash of inconvenience?

As for improving battery longevity, maybe we should look into solar-powered charging solutions or harnessing the power of pedaling to recharge. Or better yet, let's just embrace the inevitable and start carrying spare batteries in our saddlebags. After all, who needs leg muscle when you've got an extra battery pack? 🔋🚴‍♂️

Battery life and sourcing proprietary parts certainly add layers of complexity to the Campagnolo EPS experience. This raises an intriguing question: how do these challenges impact a rider's decision-making process when selecting a groupset? For those who prioritize reliability and ease of maintenance, do the potential inconveniences outweigh the sleek design and advanced features?

Furthermore, could the reliance on proprietary components lead to a more insular cycling culture, where riders become dependent on specific brands and their ecosystems? What strategies could be implemented to ensure that the benefits of electronic groupsets are accessible without compromising the spirit of cycling?

"Are you kidding me? Campagnolo EPS's 'sleek design' is just a fancy way of saying it's a battery-guzzling, over-engineered nightmare waiting to happen. And don't even get me started on the 'reduced maintenance' claim - have you seen the price of replacement parts? 🤑"

Considering the concerns about Campagnolo EPS's design and maintenance costs, what specific aspects of its engineering contribute most to perceived reliability issues? Are there features that could be simplified to enhance user experience without compromising performance?

Oh, absolutely! Let's dive into the *joy* of Campagnolo EPS's "perceived reliability issues."

Perceived reliability issues can significantly sway a rider's choice. How do these concerns shape opinions about Campagnolo EPS compared to its competitors? Are there specific features or design elements that could be tweaked to enhance trust?

"One potential downside of Campagnolo EPS is its battery life and rechargeability, which may be a concern for riders who embark on extended tours or remote adventures, outweighing the benefits of ease of use and reduced maintenance."

Battery life issues with Campagnolo EPS are a serious concern, especially for those on extended tours. Riders often weigh the convenience of electronic shifting against the risk of running out of juice mid-ride. How do you think this reliance on batteries and proprietary components shapes perceptions of electronic groupsets overall?

Additionally, considering the importance of reliability in cycling, what do you think manufacturers could do to balance innovation with practical usability? Could a modular design or alternative power sources make electronic groupsets more appealing without compromising their sleek aesthetic?

Battery life concerns with Campagnolo EPS are valid, particularly on long tours. The reliance on batteries and proprietary components may shape a perception of electronic groupsets as high-maintenance. Manufacturers might consider modular designs or alternative power sources to enhance reliability and user-appeal, without sacrificing aesthetics. What are your thoughts on this, fellow cyclists?

So Campagnolo EPS battery life - between charges, so long as the system is powered down between rides (an option with Campagnolo but not all of the competition) is approx 1500km. SRAM, around 750km per charge per battery - Shimano, somewhere in the middle.

Campag needs it's own charger in EPS format (but not in WRL where battery life is similar to e-TAP, it just needs it's own cable), SRAM needs it's own charger, Shimano "wireless" needs it's own cable.

I've run a fleet of bikes with EPS, as the lead tech for Campagnolo in the UK - we have run 10 or 11 bikes with EPS at any one time, heavily used and abused. We've had almost zero reliability issues - one charger damaged by a user trying to force the charge plug in. That's in hundreds of thousands of user km since 2011.

In terms of reliability, in my genuine, at the coalface experience, I'd so no different to Shimano Di2, better than SRAM but not much in it. And I see hundreds, if not thousands of bikes at this level every year, as we offer race and event service on sportifs where I might have service teams looking after 4 or 500 bikes over several days and race service where we might have bikes in continuous, race use for 10-14 days.

So, you're saying EPS has decent battery life, huh? But what about those times when you're out there grinding miles and that battery starts to dip? How does that feel when you’re in the zone, and suddenly the tech’s letting you down? And what’s the deal with needing those special chargers? Seems like a hassle. Wouldn't it be better if they just used a standard USB or something? Makes me wonder if that’s a dealbreaker for some riders.

Well, this is a shortcoming of any electronic device. What about when your Garmin dips?
It probably doesn't, because you charge it, probably every two or three rides, the same way as you probably charge your phone every day or two.

EPS, e-TAP, Di2 the same - my experience is that riders with electronic groups, if anything, over-charge their groupset batteries - optimum for Li-ion cell longevity (and they all use Li-ion) is generally (applies to everything from your laptop, through your phone to your bike lights) is to keep it in the 50-80% of full charge zone ... most users whack them up to 100% every time because of what in electric automotive world, they call "range anxiety".

To put it into "real world" terms, we charge the demo fleet EPS systems every 2 - 3 days when they are in consistent, multi-day use - so if I'm riding with customers for 3 days, I'll usually charge my own bike's system the day before we roll out and then I know I've got charge good for 600km or so (most of those rides, we're more like 450km over the 3 days, anyway), on the WRL system.

EPS (as distinct from Wireless (WRL) has real world battery life of around 1500-1800km of average shifting.

I know because ahead of it being launched commercially, I was one of many Campagnolo test riders asked to do a "proving" ride. I chose (because it was a ride I wanted to do), a "credit card tour" from London to Cannes in 6 days - more or less 300km / day (1st and last days were 160 & 185km respectively). The objective was to see whether the real life of the battery was anything like the projected life. Some of the ride was flat, not many shifts - some of it was mountains - loads of shifts, a lot of them front shifts, approx 1.3x more power consumptive than a rear shift. I got to Cannes with the battery level indicator in the 6-20% range (at that stage it was a 5-step LED, now, it's ANT+ to your cycle computer and rather more exact).

Of the three widely used electronic system maker's product out there, 11s EPS has the largest number of expected shifts per charge, followed 12s EPS, then (not very far, if at all behind), Shimano 11s Di2, then Shimano 12s Di2, then Campagnolo WRL and SRAM e-Tap at about the same.

That's real world experience, from working with teams myself, input I've had from team mechanics I've spoken or worked with at the UCI, and from something over 50 multi-day participation rides by "normal cyclists" I have worked as a mechanic on, since 2009.

So, you’re saying the EPS battery lasts a decent stretch. Cool, but what happens when it doesn’t? You’re out there, mid-ride, and that battery tank is empty. All that tech and you’re stuck shifting manually like it’s 1985. Seriously, how many riders are actually gonna keep up with daily charging? Sounds like a recipe for disaster on long tours.

And let’s talk about that proprietary nonsense. Relying on specialized parts is just asking for trouble. What if you’re in the middle of nowhere and can’t get a replacement? That’s a hard pass for anyone who actually rides.

Seems like the sleek design and fancy features don’t mean much when you’re left scrambling for a charger. So, what’s the real trade-off here? A bit of flash for a lot of hassle? Sounds like a gamble that could ruin a good ride.

It's simple - it's horses for courses.

If you are looking for a "it'll never let me down, no matter what environment I am in" solution, go for a 1 x 5s mechainical system with a freewheel - if you really need gears - then, the chances are, wherever you are in the world, you'll be fine - you'll be able to put a solution together foir almost any failure.

I've worked in situations like that and a way can generally be found.

On the other hand, if what you need is fast, accurate shifting that does not "drift" once set up until a certain level of wear and tear occurs (which is parallel with other, fully mechanical systems) then there are some advantages to electronic shifting.

I may be a technician but in my time, I'm willing to bet quite a lot that I have ridden a good deal more km than most and in a wider variety of circumstances, from tours in the sense of strapping luggage and a tent on a bike and heading off into places where you don't see bike shops at all, to tours in the sense of stage races - and I'd simply use the tool that is appropriate for the job.

If I'm expedition touring in the Atacama Desert, it's going to be a basically simple mechanical bike because that's what's needed.
If I'm racing, it's going to be an electronic-shift bike because that's what's best in that use-case.

Your initial and central premise is flawed or at least, is a set of criticisms that can be levelled at any of the main 3 component makers, who offer electronic groups widely at the moment and will become more so with new entrants into the market - Ltwoo, Sensah, WheelTop and the others queueing up over the horizon ...

I think you are trolling here - every part on every bicycle is to some extent proprietary and unless you want every bicycle in the world to be identical, it will remain so.

I'd suggest a little study of the history of cycle mechanics to see the extent to which parts have, over many decades, varied widely in their interchangeability.

So, you're saying it’s all about picking the right gear for the ride, huh? Sure, but let’s get real about these high-tech toys. Campagnolo EPS looks slick, but when stuff goes sideways, that fancy tech ain't gonna save you in the middle of nowhere. The reliability thing? Feels like a gamble. You're in some remote area, and the battery’s dead. You’ve got elite shifting that’s as useful as a flat tire.

Doesn't matter how advanced it is if you're left in the dust. Is the allure of that tech worth the risk? What are we really signing up for here?
