SRAM's electronic eTap shifting has been six years in the making, with its much anticipated reveal to the world finally arriving with the 2015 Eurobike and Interbike trade shows. We're celebrating its arrival by incorporating the eTap derailleurs and shifters into the complete Red eTap Road GXP Groupset, which includes all the bits required to outfit a dream bike. Minus the obligatory power meter, the Red eTap Groupset comprises the same electronic and standard Red 22 components that outfits like Team Ag2r-La Mondiale and Team Katusha will be riding in anger this year. As such, the Red GXP crankset, GXP Team bottom bracket, XG-1190 cassette, and Red Aero Link brakes are all SRAM's top-end models, but the real draw of this groupset is obviously the long-awaited electronic shifting.

From the earliest prototypes, eTap's wire-free system hinted at clean lines and a potential to change the way we think about electronic shifting. The final production group doesn't disappoint, setting what will likely become a new standard for the cycling industry with updated ergonomics and impeccable wireless operation. It lets you say goodbye to broken shift cables that leave you stuck in the smallest cassette cog at pivotal moments, shake off worries of errant debris buffaloing a mechanical or electronic derailleur cable from its proper placement, and welcome a bicycle free from aesthetically unpleasant shift cable housing.

We got our first look at an eTap prototype a couple of years ago out on the roads of Chicago, where it was not-so-stealthily disguised behind a clunky, fake port box amidst swirling rumors of a SRAM electronic system in development. (We've also seen what looks to be a hydraulic disc version clandestinely populating certain sponsored 'cross machines, but have no official word to relate. Yet.) As mentioned above, the final version has been tidied up quite a bit, eliminating the camouflage to reveal the drivetrain's simple, clean beauty.

SRAM's proprietary Airea communication protocol is the brain of the system. Airea creates a unique, 128-bit encryption code that securely pairs the shifters and derailleurs, resisting both hacking and jamming for worry-free shifting even in a pack of other eTap steeds. Unlike other electronic drivetrains, SRAM's system is closed and does not allow shift reprogramming, which is actually a refreshing dose of user-friendly simplicity in an industry that can occasionally get lost in minutiae. SRAM is confident that the eTap shift logic delivers an optimal shifting experience across road-related disciplines without requiring a host of minor tweaks — an ethos developed and proven by the company's mechanical road and mountain lines.

If Airea represents the system's firing synapses, the bodies they control are the derailleurs. Featuring the Exact Actuation technology found in mechanical Red derailleurs, the eTap rear derailleur manages the narrow spacing of an 11-speed cassette for reliable shifting accuracy with every click of the lever. It also allows for multi-gear shifts with an extended depression of the shift lever, so it's spry enough to help you respond to any sudden attacks. The front derailleur boasts SRAM's Yaw technology, another carry-over from the mechanical groups. Yaw rotates the cage ever so slightly as the chain runs across the cassette to maintain an optimal chain line and reduce chain rub for quiet, precise shifting and efficient operation across the entire range of gears.

The shifters' bodies look similar to the mechanical Red 22 shifters but carry less weight and a few tweaks for notably more comfortable rides. The entire hood enjoys a smaller profile without all those internal mechanical workings, allowing a more ergonomic shape that sits comfortably in your hands without compromising a secure hand/hood interface. Adjustable reach on the levers accommodates a wide variety of rider hand sizes for easy shifting and braking.

The shift paddles sit under the brake levers in a similar position to the mechanical version, but they use eTap's peculiar shifting logic — arguably the most pronounced departure from traditional shifting in decades. The right lever directs the chain down the cassette for a harder gear, the left lever guides it up the cassette for an easier gear, and simultaneously engaging both levers shifts the front derailleur between the chainrings. We suspect this system was built with one-by in mind, but we're also able to adapt to it with a double crankset after just a few minutes of throwing levers. Each shifter also features ports for compatibility with SRAM's separately sold Blip shifters, offering virtually endless potential for shifting access from the drops or the flats.

The front and rear derailleurs each carry their own a rechargeable battery pods, which click into place quickly and easily and are interchangeable between the two derailleurs. With their claimed 60-hour ride times, you shouldn't have to worry about losing power, but it's nice to know that if you do forget to charge up and you run out of rear derailleur juice out on the road, a two-second battery swap from front to rear will get you back up and running with full access to the cassette range. SRAM claims that 60-hour run time means a fully charged rear derailleur battery will last over 1000 kilometers or 620 miles, with the front derailleur lasting even longer because of its relative dearth of use compared to the rear.

Each shifter is powered by a CR2032 coin type battery with a predicted lifetime of two years when riding an average of 15 hours per week. To keep tabs on the various battery statuses, each derailleur and shifter features an LED indicator light to communicate battery life, with green, red, and flashing red stages to clearly relay power levels. Each component also incorporates an accelerometer that puts it into sleep mode when stationary to conserve battery, and wakes it up for full functionality when your bike is in motion.

SRAM claims eTap has been extensively tested in a wide range of riding conditions, both in the real world and the lab to ensure reliability; as we mentioned above, we've actually seen evidence of this on the roads and 'cross courses around the country. Given the cold-weather tolerance issues of its first generation hydraulic road brakes, we're particularly pleased to note that SRAM specifies that eTap has undergone testing in its in-house climate chamber, proving the group's reliability in temperatures ranging from -20 degrees up to 120 degrees Fahrenheit.

The SRAM Red eTap Road GXP Groupset comes complete with right and left Red eTap shifters, a RED eTap front and rear derailleurs, a Red GXP Crankset, a Red Aero Link Brake Caliper Set, an XG-1190 Cassette, a SRAM GXP Team Bottom Bracket, and a Red 22 Chain. The electronic components are supplemented with an eTap Powerpack for derailleur battery charging and an eTap USB firmware Airea update stick.

The future is here, and it ROCKS

  • Familiarity: I've used it several times

For those of you who have chosen to abstain from cycling-related media for the past couple of years, eTap is SRAM's bluetooth-connected answer to Shimano's long-standing Di2 electronic shifting system, and it is INCREDIBLE. The right shifter moves up the block, and the left moved down. Tapping them together controls the front derailleur. Now, as something of a traditionalist, I resisted this notion when I heard it for the first time, but after riding it, I can't get over how brilliant it is. It took me less than a quarter mile to become completely comfortable with the new shifting pattern. The buttons are nice and large, right around the size of a quarter, only square. Each push of the shifter comes with a nice, positive click, and the derailleurs react instantly. Performance benefits aside, you'll probably shift twice as much as you need to for no reason other than the fact that you feel like RoboCop. eTap gets a 10/10 in my book.

Like having a brand new bike

  • Familiarity: I've put it through the wringer

I purchased two SRAM Etap groups to upgrade both my wife’s and my road bikes. Both bikes had relatively old drivetrains (hers 10+ year old Ultegra and me 15 year old Campy Record) so we figured it was definitely time for an upgrade and because our bikes have S&S couplers the wireless aspect of Etap made a lot of sense for breaking down the bikes for travel.

Installation: Etap was far easier to install than any other build I have done. After removing all the old parts and degreasing the frame and giving it a good scrub, I had everything installed in about an hour and a half, the most time consuming part being the brakes. SRAM has some excellent YouTube videos explaining how to install the parts and after viewing them a couple times, it was pretty straightforward. One thing to watch out for is the braze-on adapter. We have titanium bikes which require this adapter and I tried using the Shimano one that was on my wife’s bike from her previous group. With this adapter, adjusting the front derailleur was impossible, but once I switched to the SRAM adapter everything worked normally. I know, it’s probably obvious but I just figured there was some cross compatibility between SRAM and Shimano but it appears that’s not the case. Minus points for the braze-on adapter being a separate component that we needed to buy to complete the install.

Adjustment: this part was surprisingly easy, especially compared to mechanical groups I have worked with in the past. SRAM’s video instruction was clear and concise and the front derailleur has little marks on it showing where it needed to be mounted in reference to the large chainring. The rear derailleur was equally easy as well, just use the micro-adjustment buttons on the shifters to line it up with the large and small cogs of the cassette respectively. Once that was done, I fine tuned the adjustment by putting the bike on the trainer and riding it, adjusting as needed with the micro-adjustment buttons on the shifters while shifting into every gear.

Riding: The first ride felt like I had a brand new bike. The difference between this and my old group (granted it was pretty old) was a revelation. The first week or so of riding I was getting Strava PRs all over the place and at my age, I ain’t getting any faster so it definitely has to be the drivetrain. The new method of shifting (left shifter easier gear, right harder, both change front chainring) took a little getting used to but now that I have, I love it. Shifts are quick and concise with no delays, clicking or grinding, even under heavy pedaling load. The brakes are also nice, with good modulation and stopping power, even on carbon rims. One final point about this setup is it’s seriously quiet - almost zero noise out of this drivetrain which is one of my favorite features.

I was a bit nervous about dropping so much money on electric shifting but once I had it on the bike those nerves disappeared. The components are high quality (as is the packaging - it seems SRAM has taken a page out of Apple’s book), the installation is really easy and the performance of the group is outstanding. I highly recommend this setup for anyone wanting to upgrade their bike.

before SRAM Red? I'd been on the same clunky old group for about a decade - noisy cables, unreliable derailleurs that only shifted when they felt like it and would drop my chain more often than not. Even tune-ups didn't really help. Cue eTap, and I am in heaven. It took me about 2 minutes to get used to the new school of shifting, and after that, it was cake. Smooth shifting every time. And with fewer cables and a new bottom bracket, my bike is so quiet! It's like having a brand new bike that I actually want to get out and ride.
