Vivo Cycling Previews All-Aluminum 12-Speed Derailleur

Back in the mid-1990s there was an influx of small companies machining their own derailleurs. Not all of them worked well, but they sure looked nice - teenage me drooled over the purple anodized Precision Billet Proshift derailleur. Nowadays, the drivetrain landscape is dominated by the two big S brands, but that hasn't stopped other manufacturers from trying to get a piece of the pie.

Earlier this year, Vivo Cycling announced their ultra-customizable (and very expensive) shifter, which allowed buyers to select everything from the paddle shape to the cable tension adjuster's design. They're now working on a derailleur to go along with it, and the initial images certainly are eye-catching.

According to John Calendrille, the company's owner (who has a long history of drivetrain development, dating back to the anodized-everything days I mentioned earlier), the new derailleur is constructed from 7075 aluminum and is devoid of any plastic parts. It's designed to work with 12-speed cassettes with up to a 10 - 52 tooth range.

Machined from 7075 aluminum, with cartridge bearings at the pivots.

There are two cartridge bearings at each pivot, for a total of eight, plus a sealed cartridge bearing at the cable pulley. All the hardware is titanium, and the preliminary weight with nylon pulley wheels is claimed to be 315 grams. For reference, Shimano's XTR 12-speed derailleur is 240 grams.

The derailleur is designed to work with Vivo's own shifter, but it should play nicely with SRAM shifters; compatibility with Shimano shifters hasn't been confirmed yet, due to the slightly different cable pull ratio. The derailleur is designed to be fully rebuildable, including the friction clutch, which is also adjustable.

The final price is expected to be somewhere between $315 - $375 when it officially launches later this summer.

 It is gorgeous, but heavier and more expensive than XTR is a hard sell. Especially since XTR is sooooo nice.
  • 82 23
 XTR still a faster shift than the other guys electric shifting options...
  • 39 6
 @dan23dan23: From what I understand about the SRAM transmission stuff, faster shifting wasn't the goal and it was designed fully aware that the shifting was going to be slower. It is more of an "easy does it" approach.

That said, still riding a Shimano Zee mech and shifter combo here Smile .
  • 54 13
 @vinay: Oh yeah, I am fully aware of what their marketing team explains as the reason for the slow shift... It's just so slow that my ADHD doesn't like it, same reason I don't watch paint dry...

Grabbing gears after a steep climb is the worst. You can dump 4 gears with XTR by the time the transmission drops a single gear.

 @dan23dan23: I’m not a huge fan of the Axs and transmission stuff. But my gravel/road bike came with it. And in the app you can set it to shift x number of gears with a button press. I haven’t messed with it. But that’s what I gather from the apps walk through. That said it’s been pretty great on that bike. Not sure I would jump to spend that much for a mountain bike drive train when the cable stuff from everyone works so well and is light and relatively cheap.

 I have to agree. I'm in the camp of "if it serves my purposes (big emphasis on reliability) then I don't care what the level or brand it is". I have Eagle XX1, X01, and Shimano 12 speed XT, but my latest bike came with 12spd XTR on it and its just incredible.
  • 10 8
 @vinay: yep. purposefully slow, to allow full gas shifts with zero worry. its a tradeoff they clearly thought the market would appreciate.

 @vinay: I’ve spent all fall on Transmission while nice and all it definitely seems like it was intended for ebikes. Incidentally it worked best on the one ebike I demoed. It was nice and shifted really smooth most of the time, but Fast on demand shifting is why I switched to SRAM nearly 20 years ago. Transmission fails in that regard. So I sold the Transmission group and picked up a fresh cable XX1 group that shifts way faster and on demand at less than half the price. Oh it’s lighter as well. I would love to see a cable version of the transmission derailleur because there are definite benefits to its design. Maybe it’s just me but I’m still not ready for electronics or motors on my bike.

 The funny thing about that is these types of CNC Derailleurs were beginning to take off in the 1990's and Shimano introduced the XTR 950 groupset with V-Brakes. These types of derailleurs disappeared over night. The CNC V-brakes disappeared also because the XTR's were so good and Shimano used predatory pricing to kill the competition.

 @dan23dan23: exactly my thoughts, can't shift faster up or down a cassette than xtr in any situation
  • 3 5
 @Bikethrasher: I don't think there can be a cable version of transmission since it has no limit screws or b tension. Every dimension of how it interacts with the frame and cassette is fixed and having cables would make that impossible since they require adjustment wouldn't it?
  • 35 0
 @warmerdamj, there could definitely be a cable version - you can even see a drawing of one in this patent drawing from SRAM: www.pinkbike.com/news/sram-granted-patent-for-drivetrain-with-a-direct-mount-derailleur.html.

Not having limit screws or b-tension adjustment isn't related to the electronic shifter - that's part of the derailleur design. The cable running from the shifter would just be there to move the derailleur up or down the cassette, the same as the current shifter does wirelessly. I'm hoping SRAM releases one eventually - a battery-free version would be great.

 @Bikethrasher: You're definitely correct, Transmission is an ebike drivetrain and nothing more IMO. It is great on an ebike because the slow shifting is basically a non-issue and it shifts so well under load. Whenever I ride an ebike I notice that I never need to dump gears and it's actually better to shift one by one while keeping the power on and the cadence up.

Whenever I'm back on my real bike I need to dump gears often and transmission just can't do that... Mechanical drivetrain with a Shimano cassette please.

 @warmerdamj: On the contrary the only adjustment needed would be the barrel adjuster at the shifter to dial in cable tension. It would be as easy to get perfect shifting as it is to get your dropper post dialed. Talk about the realizing the dream.

 The fact that this article immediately spurns the Shimano v SRAM debate is a clear indication of where the market lies. Just like their shifter, I fail to see the demand for this derailleur. Where in the over saturated bike parts world is anyone saying- I need more options for mechanical derailleurs??

 @dmnelso: For one I'm actually quite interested. Also keen to try the TRP.
Cannot be bothered with electronic shifting. The mechanical Sram has garbage in place of a clutch and I wouldn't put it anywhere near my bike. Current 12s Shimano shifts amazingly well for about a year, until I bend it enough that I have to run my hanger misaligned to keep it shifting.
The transmission was promising, but seeing it fail on 3/3 of my friends' bikes within a few rides AND still using a garbage clutch that cannot be adjusted(and costs as much as a complete XT RD to replace) is another product I'm not even remotely interested in.
So I actually hope this catches on and we get some competition, or I'll finally get to try an actual transmission near the BB. Because the current mainstram derailleur market is just pathetic.

 @sophisticatedhonky: Nah, I wouldn't call it dumb. It may just not suit you but that's a different story. It would only be dumb to splash out on one of these systems expecting quick shifts whereas they were pretty clear up front that it would be slower than anything else on the market.

A whole new redesign makes your shift slower, allowing for a smoother shift (that aligns with the "Shift Mapping". I hope that helps.

 @bmied31: I literally finish a 40k descent and absolutely exhausted looking 2m ahead of my bike I spot an abrupt transition to a steep uphill. In one full power pedal stroke shift from 12 to 1 and while it did make a noise, it was an absolutely smooth stroke. And the noise is no worse than a regular shift on eagle to be honest.
The experience has been consistent having ridden HG+ since release. It does get worse after some wear, but I'm talking hundreds of rides. The xt derailleur dies quicker than I'd like. But as long as it's adjusted properly the HG+ shift is brilliant.

 @mikekazimer: I hope they do; there’s plenty of folks (like me) who’d prefer cables on their otherwise top tier groups.

In an industry were I can buy about a million different-but-no-so-different 50mm stems, or sub $100 pedals, it would be nice to have a reasonable selection of choices of high-end mechanical groupset (well, not even ‘groupset’ - shifter & mech, since the rest can be the same as it’s electrical counterpart)

 @RonSauce: having ridden both, I've found for me that not to be true. If I literally push all my effort into a 12 speed Shimano I still get some ugly change (Far better then any other traditional drivetrain to be fair). Transmission. I have never been able to get an ugly change even under 1000+wats.

But yes, as someone who remembers well the beautiful failures of the Precision Billet and Paul's CNCed derailleurs, I can only say, can it possibly be as good as something as perfect as XTR?

It doesn't have to be better. If it's as good, the beauty can be the trump card worth the extra hundo.

 I’d argue that the “vanity” end of the bike industry is doing just fine. Plenty of people spend silly money on bikes and most of those same people aren’t impacted by a little inflation pressure.

 I really want TRP, Box, Ingrid, Garbaruk, etc. to suceed and grow. They just arent offering anything acutally better yet, and havent cracked the code on chain manufacture. The bigger pieces like cassettes and derailleurs actually maybe seem easier?
  • 3 0
 Agreed. Garbaruk seems to be doing great with cassettes. But I looked into the TRP 12s group set. It looks nice but is quite a bit more expensive and shifts worse than Shimano. So makes it a hard sell. If it shifted as good it could be justified to spend more to be unique. But not worse performance AND more expensive.

 I don't think making a chain is necessary - KMC for example already make excellent chains - their 11spd was top rated by zero friction cycling. Don't know how good their new 12 speed is yet

 Can someone explain this; "it should play nicely with SRAM shifters; compatibility with Shimano derailleurs hasn't been confirmed yet, due to the slightly different cable pull ratio." Surely the derailleur is dumb and the cassette/shifter is the issue?
  • 3 3
 Shifters and dérailleurs both have specific cable pull ratios, and need to be paired accordingly. For instance, if you take an old 9 speed Shimano MTB derailed and slap it on a new 9 speed Shimano Cues MTB shifter and cassette, it will be all wrong because the intended cable ratio of the old RD doesn’t like up with the new shifter.
  • 3 5
 @TEAM-ROBOT: yeah but.... let's say its new Sram Eagle and Shimano XT. the pull ratio is dictated by the shifter fir the specific cassette. As long as the derailleur has the range and b gap its pretty much interchangable no?
  • 6 0
 @WillW123: the Shimano and SRAM 12 speed MTB stuff is very close, but not identical. I think it's a 1.1 cable pull ratio for Shimano rear derailleurs and 1.12 for SRAM, but other places it says 1.01 for SRAM. You'll hear mixed results from people who've mixed and matched Shimano and SRAM shifters and derailleurs. Some people say it works great, some people says it doesn't. YMMV One thing I do know for sure is that SRAM 11 and 12 speed RD's use the same cable pull ratio, and it's the same for Shimano 11 and 12 speed RD's, so you can mix and match those. It's complicated out there.
  • 4 0
 @WillW123: no, I’m pretty sure the shifter pull ratio is specific to derailleur not cassette. The cassettes are cross compatible, the shifter/derailleur is not.
  • 2 0
 @kc358: could be I suppose if the derailleur has a different size swing arm parallelogram. Currently using xt shifter, xo1 derailleur, e13 cassette no issues.
  • 3 0
 @WillW123: that’s pretty much the answer. It’s a rope pulling a lever. Since all 12 speed cassettes are interchangeable, everyone is moving the end of the lever the same distance. Sram designed theirs to move that distance with 1.1 of cable pull and Shimano designed theirs to move it that distance with 1.12 meaning the levers are different lengths. They can do this by changing where the rope pulls the lever from or changing the length of the lever arm itself. There’s a trick over in the road world where you can use Campy shifters with Shimano derailleurs by mounting the cable on the wrong side of the bolt to change the pull ratio and Jtek built a business on making little pulleys to adjust pull ratios for all the wacky parts bin things you wanna try.

  • 3 4
 The reality regarding AXS being slow shifting is that current wireless tech does not allow it to happen any faster. SO, any pitch from Sram that "they wanted it that way" is spin. They built a good system for current tech capabilities and that means slower than mech systems. I love the look of this derailleur and would def try it... unless Shimano releases a new wireless derailleur that's peppy firstSmile
  • 6 3
 Huh? Have you used the first gen AXS? That thing SLAMS through gears as fast as any cable system I've had. Click 4 times back to back as fast as your thumb goes and it's done. Speed is not an issue with electronics. The slower speed was engineered in to the new AXS, simply to allow the chain to engage the cogs at precisely the right location as to shift smoothly no matter the pressure applied.

But I see zero evidence wireless tech has anything at all to do with speed. Zero.

The old axs flies in time with the click, the new lags by a full few seconds.
