Social media is bubbling with comments about recent Instagram and Facebook images of multi-time World Champion Nino Schurter riding what looks like a prototype SRAM eTap wireless rear derailleur and shifting system. The story was picked up by
Velozine, who dug up some old patent drawings of shifters and derailleurs to that effect. That said, eTap has been around for years, so there can be no doubt that by now, SRAM has a fully armed and operational group for mountain bikes. The only question is "when?" Attempts to contact SRAM have not yet borne fruit, so (in the spirit of PB) some unfounded conjecture is in order.
The rear derailleur of Nino's Scott is definitely eTap, but it's doubtful that SRAM would model it in polished silver like its road version - it wouldn't look tough enough for dirt bikes. Two explanations: it could be a modified road changer, adapted with an XX1 pulley cage (eTap Red is 11-speed); Or it could be a production Eagle wireless rear 12-speed derailleur that has been polished as a sort of camouflage to make us think it's a MacGyvered road bike mech
| The rear derailleur is not the big question anyway. We know it's going to shift and we know it will be a 12 speed. |
The rear derailleur is not the big question anyway. We
know it's going to shift and we
know it will be a 12 speed. What we are most curious about is what the shifter will look and feel like. That, however, will remain a mystery, because the shift levers are not apparent in the images. The default would be a abbreviated version of SRAM's paddle shifters that feel more like buttons, but possess a tactile and audible click - a retro solution which would play well to the change-reluctant mountain biker crowd. The more progressive solution, however. would be a pair of rubberized buttons or a single radial paddle that could be switched intuitively without moving the thumb completely off of the grip.
DIY Wireless Shifting If you had access to a small lathe and possessed some basic metal-working skills, you could splice a long-travel pulley cage from an 11-speed XX1 group to an eTap Red rear derailleur. The cassette spacing is the same as XX1, according to road bike forums. Shifters? Well, SRAM caters to the Triathlon and time trial segment with a pair of clever plug-in remote buttons called "
eTap Blips." It wouldn't be too hard to place both on the right side of the handlebar for one-thumb shifting, or if you are already paddle-shifting your sports car, you could place one button on either side of the bars and have a similar setup.
More photographs and speculationEnough nonsense for now. If I do get any facts from SRAM, I'll post them here.
made 9-56 cassette and priced it high enough you’d find a bunch of dudes who’d find it reasonable
Sram is run by marketers and business people, all it matters is sales, even if there is no public interest or if it is worst than current systems.
They own the press thanks to $$$ spend on ads. They can make it “desirable” and “innovative” very easy. Even total garbage like the rs-1 was reviewed by the largest magazine as an outstanding innovative fork.
I enjoy building the bike and just get it right. It is something takes years to learn and goes hand in hand with the pleasure of riding it.
Sure, you save 20/30 minutes when building the bike at first. We are talking about routing 2 cables.
What about the time you spend having to charge this thing every other day. Turn off, plug in, charge, disconnect, turn on and go? Updates? Battery issues?
Wanna go for a ride but forgot to charge? Go tomorrow.
I already have enough things to turn on / off / charge / update / doesn’t work / bugs / everyday...
That's literally one housing and one cable these days.
Wireless gears is nothing more than a marketing department wet dream. Same thing with 15mm axle. They've created something that nobody was asking for because bullet proof solutions were already there.
* I have snapped two short Di2 connector cables in crashes, but that's my fault for bad routing and are a cheap swap out ($10). So yeah, wireless would be even better.
I do not like the idea of wireless shifting at all because the signal only is working perfect if you use a wire.
Another thing is how much that rear derailleur will cost after smacking some of them into a rock. My eagle derailleurs aren't that good Vs older gx 11 speed. Alot more died and even the pulleys
As for charging, most people run a Garmin or GSP device. eTap doesn't need to charger any where as much as any of those items. Derailleur fully charged last 60hours, Shifter 24 months. Thats longer than a recommended lower legs service..
If you had ever touched ETAP for road, you would know this argument about spending time with bugs, charging, etc is totally off. Most roadies are getting 800 miles on a charge for their road Etap systems. For most, that's a couple months worth of riding. MTB mileage would be shorter as we shift more frequently, but even if it's 200 miles to a charge, that's a good month of riding for most people. Of all the etap bikes I've dealt with (a lot) I have yet to come across any issues with bugs, setup, programming....nuthin.
Will this replace cables completely? Heck no. Will it replace cables on my bike? You Damn right.
On another note, Anyone looking for a kidney?
So I guess I'll just take his word for it.
On that topic, when is either Sram or Shimano going to make electric shifting with a clutch. This is long overdue for CX and gravel riding.
Also, Shimano does make Di2 with a clutch. XT and XTR both have clutches and work with drop-bar kit just fine. The only caveat with mix and match Di2 setups is that your FD and RD have to either both be road or both MTB (eg can't have Ultegra FD with XTR RD). The easy workaround is running 1x, which happens to be stellar for cross.
I’ve been running an XTR di2 rear derailleur on my CX bike for almost 2 years. It shifts terribly with anything but a wide range cassette, so no, it is not ideal for CX unless you want big jumps between gears. The slant on the parallelogram makes it horrible with even a large road cassette like an 11-32.
How does adding a battery and a heavier, more expensive derailleur etc benefit me?
All that complexity, a servo motor, battery etc for the feel of a button? That is the iPhone generations form over function thought process if ever I've heard it.
(Shimano ftw, by the way )
When road hydraulic brakes came out, they had to recall thousands of bike.
Tiso, a small size component maker from Italy, that has been around longer than sram, already had 12 speed and wireless shifting in 2014.
I run XTR brakes, but I'm so glad I didn't settle for Shimano 2x once X01 was available. Now there's not much difference again, but for a few good years, SRAM was way out in front.
Journalism seems to be taking a unique twist these days. Back in the days you had "spy shots" where the athlete poses with the bike. Nowadays research and conclusions are based on pictures on social media. I'm starting to think that there are Russian Gwin and Schurter stunt doubles, just to upset Pinkbike.
Batteries take a long time to die and it's so small, just put a reserve in your pack, or on the bike, or in your pocket
Really... so this is just a little more BS until you actually have something to report.. thanks RC for such fine journalism. Let's get some facts together
If your willing to commit to a battery it should plug into the shock and seatpost as well.
Syncro Shift for 2x is pretty cool cause it works like simple gearbox. But 1x? Who needs it?
Are you listening shimano???
My mechanical XTR is great, even though electric XTR exists. The same will apply to you as well, unless you're just interested in running a bicycle fashion show out in the woods :/
