SRAM Red eTap Electronic Upgrade Road Bike Kit
The next evolution in shifting is here. Did we say evolution? Sorry, we meant revolution.
SRAM's new Red eTap is shifting like you've never seen it before. Free from wires, cables, and clutter, eTap is the bike in its most distilled, simplified form. Easy and intuitive to use, beautiful to behold, and simple to set up, SRAM have defined what a road bike can and should be.
Let's start up front with the shifters. The first thing you'll notice is that there are no wires, and the only cables go to the brakes. That's because eTap shifts wirelessly, using SRAM's ultrasecure Airea wireless protocol. Airea is a 128-bit encrypted signal that was developed in conjunction with engineers, computer security experts, and even hackers. It's designed to be unbreakable, and interference-free, so you never have to worry about losing a shift to interference from other radio operated devices (like garage door openers, phones, etc...) or worry about someone hijacking your system. Since the signal moves at the speed of light, you also get ultrafast shifting with the reliability and speed you've always expected from SRAM.
You'll also notice that there's only one paddle shifter on each shifter. So how does that work with electronic shifting you may ask? Simple. SRAM has reimagined how a bike shifts, drawing inspiration from F1 paddle-style shifters. To shift to a harder gear, click the right lever. To shift to an easier gear, click the left lever. To shift the front, click both levers at (about) the same time. Admittedly, it does take a few minutes to get used to...but only a few minutes. It's simple, intuitive, and easy. The lever also has a really nice, firm, tactile feedback 'click' sensation, so you'll get positive feedback that you've shifted in the heat of battle or while wearing gloves. The shifters feature full reach adjust, and run on CR2032 coin batteries with a 6-24 month life, depending on use.
Looking back towards the derailleurs, things retain the shifting ability SRAM is known for. The short cage rear derailleur can accommodate up to a 28T cog, and delivers up snappy, responsive shifting across all 11-cogs. The front derailleur benefits from SRAM's already impressive YAW technology, but gets the roughly 40-60nM oomph of shifting force that only electronic can deliver. That means you can shift the front under power or at high speeds without worrying about the chain hanging up, or waiting for a deadspot in the pedal stroke. Both the front and rear derailleurs use external batteries with fully sealed, waterproof components. This stuff is pro-tested, so it's been through the worst the elements have to offer and has stood up to the ultimate tests. The batteries are also fully interchangeable, so if the rear derailleur dies on your ride, you can simply stop and switch it with the front to get more juice. Each battery is good for about 100 hours of riding, depending on use, and they charge pretty quickly. Pairing the derailleurs to the shifters is a simple procedure that takes less than 5 minutes. We tried it, and were amazed at how easy set up was.
Also included is the Airea firmware USB updater. Simply plug into your computer, and pair it with your eTap system to take advantage of the latest software diagnostics and firmware updates that SRAM offers.
So if you're ready to take your road bike to the next level, leave the wires and cables behind and choose eTap. It works with any bike, and couldn't be easier to set up. If eTap is for you, hurry, initial stocks are limited.
