Whenever I talk to people about electronic shifting, someone inevitably freaks out. “OH MY GHAWD WHAT IF YOU FORGET TO CHARGE YOUR BICYCLE AND IT STOPS SHIFTING IN THE MIDDLE OF A RIDE?!?!”

Obviously, electronic shifting isn’t for everyone. Like any system, it has advantages and disadvantages. I wouldn’t condemn anyone for their preference for mechanical shifters, just as I don’t expect to be condemned for generally preferring rim brakes over disc brakes.

However, let’s at least base our preferences on facts and reality, rather than “alternate facts” derived from wild conjecture and irrational fears.

In the case of electronic shifting, running out of battery power—whether thru actively depleting it without recharging or through letting the bike sit idle for months—will never be an issue for typical riders.

I started riding electronic in April 2013, more than four years ago, when I bought a bike featuring Shimano’s new Ultegra Di2 10-speed groupset. I’ve put 13,000 miles on that bike, or over 3,000 miles per year. And the data from my Di2 system tells me that on average I shift every 20 seconds while riding.

In all that time, I have never once depleted the battery. Was I a battery-charging maniac? Not at all. I usually charged it just three times per year: something like March, June, and September. And I virtually never had less than 50 percent charge, even if the bike sat idle for six months through the winter.

Until this year, I was getting 1,500 to 2,000 miles of riding on a charge. But in May I added another component to my system: the D-Fly wireless kit, which allows my electronic shifting system to communicate with my bike computer, to add gear shifting data to my ride logs and display what gear I’m in and how much battery I have left.

The D-Fly draws power from the battery to wirelessly transmit ANT+ data to the bike computer, so that noticeably reduced my overall battery life. But even with the D-Fly attached, I’m still getting two months and more than 1,000 miles of riding out of a single charge. Battery life simply hasn’t been an issue.

The people who cite battery life as a reason to avoid electronic shifting seem to think we’re still living in the 1980s, when NiCad batteries were state of the art. I have news for you: lithium batteries are lighter, smaller, have way higher energy density, don’t spontaneously discharge themselves over time, and don’t lose capacity by developing a “memory” after charging. Welcome to the 1990s; please update your expectations accordingly.

The only instance where battery life might be a limitation would be for ultra-endurance rides of greater than 1,200 miles where you couldn’t stop for an hour to recharge. I don’t know of anyone who rides 1,200 miles without sleep… Still, the obvious answer to that: carry a fully-charged spare.

For any normal rider, running out of juice is simply not going to be a concern.

Of course, I’m not saying electronic shifting is for everyone. I do appreciate the advantages of never breaking a shifter cable, never missing a shift, never worrying about crosschaining, and having gear and shifting data in my ride log. But I also acknowledge its drawbacks: it’s more expensive and can be really finicky to setup.

But running out of battery in the middle of a ride simply doesn’t happen, and anyone who says otherwise is either very misinformed, grossly incompetent, or intentionally lying to you.

Okay, I’ve put about 800 miles on the new bike, including two centuries and one epictacular 130-mile ride yesterday (more on that shortly); it’s time for the full-blown review.

When I set out on this (bike-buying) journey last fall, I knew it would be difficult to find a bike that would live up to my experience with my old steed, the Plastic Bullet. It served me very well, and I put 22,000 miles on it. So the bar was already set very high for the new bike.

For that reason, and because I wound up buying the exact same model, I won’t say that the R2 is a radical improvement. The geometry is almost identical, and even the curb weight is the nearly same as the old bike (the 2.5-ounce difference being about the weight of $3 in quarters).

That might sound underwhelming, but for me, finding a bike that can live up to the legacy of the Plastic Bullet (PB) is a really awesome thing. And I’m doubly appreciative of that, given the large spectrum of poorly-suited bikes that I test-rode! So despite it not being a quantum improvement, I’m absolutely and unreservedly delighted with the R2.

Although I make it sound like it’s just the same as my old bike, it’s really not. Aside from being sleek, shiny, and new, it’s no less than seven model years newer, with all the improvements and refinements that implies. I really think it rides noticeably better than the PB.

One change is that Specialized has tuned the bike a lot by altering the tube shapes. The beefier chain stays make the drive train stiffer, the thinner seat stays are more flexible to ease road feel, and the head tube (which is disproportionately large in my 61cm size) is less ugly/noticeable than before because the tubes arc and gracefully ease together where they join.

They also flattened the top tube like a squashed cylinder. That might not sound important, but it’s an unexpected convenience when stopped, when I (like many riders) will sit on the top tube. However, the lesser top tube height makes it a more difficult place to affix a name decal!

The handlebars are likewise flattened on top, providing a more ergonomic place for one’s hands. And of course the Roubaix’s classic polymer “Zertz” vibration-dampening inserts improved over the years, as well.

One of the more noticeable differences is that the R2 uses internal cable routing. That gives the bike a cleaner, refined look, but sometimes confuses me, because when I used to work on the PB on a repair stand, I’d stop a rotating rear wheel by reaching up to the top tube and yanking on the exposed brake cable that ran alongside it; no exposed cables on the R2!

A major difference that worried me initially was the move from a triple chainring to a compact double, and the consequent loss of top- and bottom-end gears. Of course, I never think about needing either an easier or harder gear during regular daily riding, but I have noticed it on hilly rides, where my old triple gave me both easier gears for steep climbs and higher top-end gears for faster descents. So far that hasn’t been a show-stopper for me, but we’ll just have to see how it goes. I expect mountainous rides will be more challenging than they used to be.

I was also concerned about the shifting reliability of the compact double (they tend to be balky because of the large difference in size between the large and small chainrings), but that has been admirably handled by the electronic brain drivetrain.

Which brings up the biggest, most obvious difference with the new bike: the Di2 electronic shifting, which I’ve pretty thoroughly described in a previous post. I can’t say it has been 100 percent flawless, but it’s definitely close (much closer than old-school mechanical shifters), and in the long run I’ll be very happy that I spent the extra money.

I recently toggled its software flag for multi-shift, which lets me swap two or three gears with one long button click. That makes it a lot easier to navigate urban streets, with all the stopping and starting you have to do in town, and has perfectly addressed the only complaint I had about my bike’s electronic brain. I’m only 60 days in, but Di2 has been a daily delight.

And there’s always the cool factor of the sound of electric servo motors moving the derailleurs into a new position. During my first group ride on the new bike, after one front chainring shift my buddy Joe called up to me from behind, “Dude… Are you a robot???”

Damned right! I’m a macheen!

So while you might not have noticed much enthusiasm in my comments to date, I’m absolutely delighted with the new bike. I went into the process with extremely high requirements, and R2-Di2 has surpassed even those expectations. I was looking for the best bike on the planet, and I’m very happy to say that I think I found it.

Ride on! Right, R2?

(Photo essay still forthcoming…)

Last fall, when I kicked off my search for a new bike, it was clear what I wanted: something just like my old bike, but better. The “Plastic Bullet”—a 2006 Specialized Roubaix Expert—had served me very well over the years, and I had nothing to complain about, save that it was showing the signs of age. Because of that, the new version of the Roubaix was at the top of my list when I started thinking about a new bike.

However, a lot has changed since 2006. There are a lot more bikes out there, and I didn’t want to stick with the Roubaix if there was something better to be had. So I decided to shop around and ride a bunch of bikes, exploring new technologies like disc brakes, electronic shifting, SRAM shifters, and so forth.

I tried everything out and enjoyed the process. I test-rode eight bikes, with a collective price tag of $32,300. I learned that I hate disc brakes, SRAM shifters, FSA components, integrated seatposts, and pretty much all bikes manufactured by Trek. On the other hand, I really liked Shimano’s electronic shifting, the Cervelo R5, and Giant Defy Advanced.

Roubaix

But above all, I learned that the Roubaix still seems to be the best all-around bike for me. It fits me and my style of riding well, does a great job absorbing road vibration, and strikes a good balance between ride-all-day comfort and ride-all-out performance.

To make a final decision, I had my LBS bring in a Roubaix that was nearly identical to the one I was looking at. After test riding it, I went home pretty well convinced that I’d be buying the exact same damned bike I bought back in 2006: a Specialized Roubaix Expert. I’d still have to special-order it though, because dealers simply don’t stock bikes my size.

An hour after that test ride, I received an email from the shop, indicating that the following week Specialized would be offering a manufacturer’s discount on that bike: a 20 percent price cut, or a $1,000 savings! Needless to say, I jumped at that. A long two weeks later, I took delivery.

So how is the new bike different from the Plastic Bullet? Aside from being newer, there are really only two significant ways.

One is the Shimano Di2 electronic shifting. I’m pretty excited about that, but I don’t need to say too much about it here, having already written about it in one of my test ride roundups back in September.

The other is that while both bikes are primarily clear-coat over carbon fiber, the new bike has red and white highlights (ironically, those are my high school colors), rather than blue and silver. So the blue tires are gone, and I’ll have some extra work coordinating accessories to match the new color scheme!

Which brings me to the real question: what to name it! This is also a little two-part story.

First, it’s my second Roubaix. To honor that, let’s call it Roubaix-2, or just “R2”.

Second, its most interesting feature is the electronic shifting: Shimano’s “Digital Integrated Intelligence” or Di2.

Put those together and you get the new bike’s moniker. Allow me to introduce you to R2-Di2! The reference to the iconic Star Wars robot is intentional, and appropriate for a bike with electronic shifting. It even makes cool robot noises as the servos shift the derailleurs to change gears!

Having only received it Tuesday, I haven’t got much to say about its riding characteristics just yet. I’ve still got to get it properly fitted and add a bunch of accessories to it before I share any pictures. So it’ll be a few weeks before I have a lot to share, but be patient; those’ll all come in due time.

Of course, saying hello to R2 means saying goodbye to “R1”: the Plastic Bullet. After seven years and 22,000 miles—including seven Pan-Pass Challenges and dozens of century rides—we’ve unrolled an awful lot of road together. It’ll still see the tarmac from time to time—on rainy days or city errands where I don’t want to break out the new bike.

But as of today, she’s second saddle. It’s time to start making a new history of travel adventures with the R2. Stay tuned!

It’s been a couple weeks, but I figured I should capture some notes from my first weekend of shopping for a new bike and doing test rides. Maybe this will be useful to you, maybe not.

On the process:

As the buyer, you’re in the driver’s seat. Take your time and check out everything the marketplace has to offer. Put the new innovations to the test. Ride a lot of bikes from all over the spectrum—even stuff you have no intention of buying—and have fun doing it. There’s a lot of good bikes on the market and it can be hard to choose between them, but in the end, something will speak to you.

The one thing to be careful about on test rides: remember that you’re evaluating the bike, not the fit or the gearing or the saddle or the derailleur adjustment or the wheels, because all those things can (and will) be changed. So what’s left? A little of this and that: road feel, frame fit and finish, handlebars and stem, weight…

On the SRAM gruppo:

SRAM wasn’t a player when I bought my last bike, and everyone crows about how great their gruppo is, so one of my first goals was to put it to the test.

What I found didn’t impress me. Their stuff’s light, but I think it’s poorly designed. My main complaints revolve around how their shift levers work: push halfway and you shift into a harder gear; push further and you shift into an easier gear; push farther still and you shift into a second or even a third easier gear. Great idea, right?

Wrong. First, when I jumped multiple gears I found it hard to calibrate whether I was downshifting two or three cogs. That can be annoying when you’re searching for just the right gear ratio.

Much worse things happen if you are on a steep ascent and go to downshift but only manage half a throw, which actually causes you to upshift into a harder gear! And if you already happen to be in the largest cog (easiest gear) and try to downshiftpast that, SRAM only blocks the far throw of the lever; it’s perfectly happy to accept half a throw, which again causes you to upshift: exactly the opposite of what the user intended. And that’s my definition of “bad design”.

Another thing I’m used to doing with my Shimano setup is shifting both front and rear simultaneously. By upshifting one while downshifting the other, I am able to make a smaller jump between gear ratios than if I just shifted the front chainring. On Shimano it’s easy, because you can throw matching levers; but on SRAM, it’s confusing, because you have to remember throw one lever halfway and the other one all the way.

So even though a lot of people juice over SRAM’s gruppo, I found a lot to dislike about it. Combine that with SRAM brakes’ weaker stopping power, and I’ve pretty much ruled them out right from the start.

On Shimano’s Ultegra electronic gruppo:

Another thing I wanted to try out was Shimano’s brand-new enthusiast-level electronic shifting. I’m not a huge fan of technology for its own sake, especially when you have to pay a big premium for it. On the other hand, a lot of people have been pleasantly surprised by the electronic Dura-Ace components, so I figured I’d ride these for myself, even if I was unlikely to spend money to have battery-powered servos to do my shifting for me.

The bottom line is that it’s just as slick as promised. The shifting was quick, smooth, effortless, and intuitive. It was nice… but I had expected it to be nice.

What I hadn’t expected were some of the implications. Because the electronic shifter cable isn’t under tension like mechanical cables, there’s no risk of a shifter cable ever snapping, which has happened to me two or three times on long rides. And since it’s not under tension, a new shifter cable doesn’t stretch, so there’s no need to go back to the bike shop to have derailleur adjustments done after a tune-up.

Not that you’d ever have to anyways, because the electronic shifters automatically adjust to keep the chain centered on the cogs. That means you’ll never have chainskip or balky shifts or need any adjustment of your drivetrain. Even if you do the most ridiculous crosschaining, the system adjusts the derailleurs and chainline to avoid the loud complaints that a mechanical setup would experience.

In other words, you wind up with a completely reliable, nearly foolproof, and maintenance-free drivetrain that you don’t have to think about at all. That has nearly sold me on Shimano’s Ui-2 gruppo.

The only things holding me back? It’s heavier than a mechanical gruppo. It’s a hell of a lot more expensive. And I have questions about its vulnerability in a crash scenario.

Definitely worth looking into if you’re in the market.

On Trek’s Domaine:

Another thing I wanted to try was the Trek Domaine. Trek is known for making Lance Armstrong’s bikes, but this brand new model is their first foray into the endurance bike market, which expects a fast bike with a longer wheelbase and more upright riding position.

Now, I’m biased against Trek. I’m usually not a fan of the favorite, whether it’s Lance Armstrong or Trek as the 300-pound gorilla in the mass-production bike market. But I wanted to give them the benefit of the doubt and ride this bike, since it ought to be a worthy entry into a fairly specific market.

It was also hard to get over Trek’s strident enforcement of how the name should be pronounced: doh-MAH-knee. As a designer, if you have to browbeat the user on something as basic as what your product is called, you’re probably doing it wrong.

I actually rode two Trek bikes—the other a Madone—and on both of them the chainstays flared out so wide that I found my heel kicking them on every pedal revolution. Both bikes were surprisingly heavy, too. The Doh-MAH-knee, despite being a comfort bike, did nothing to smooth the ride over rough pavement; it transmitted every shock, bump, and vibration from the road straight into the rider’s body.

I rode the Doh-mah-knee in the hopes that this new model would show me something that would overcome my natural aversion to Trek as a household name. While their bikes were okay, there was nothing outstanding about them that would lead me to choose them over more established and better performing endurance bikes.

The only thing that almost impressed me was Trek’s “Project One”, which basically allows you to choose what components your bike comes with. That’s a huge benefit over most bike companies, whose models only come in one or two configurations. But even Project One only lets you select from a very tiny spectrum of approved alternatives, so their vaunted configurability is actually not much more than a nominal advantage.

So don’t expect to see me riding up on a Doh-MAH-knee any time soon.
