TRP x Classified Launch Vistar Wireless 1×16 Drivetrain!

31 Comments

Last year’s premium mechanical mountain bike drivetrain was just a warmup to TRP’s big drivetrain ambitions, and now, along with Classified, they’re unveiling two wireless, electronic-shifting wide-range 1x groups for both road and gravel bikes!

Called Vistar // Powershift, the group pairs a wireles derailleur and 12-speed cassette with Classified’s two-speed internally geared hubs, they achieve a wider range of unique gears – up to 530% range with an 11-40 cassette.

That’s massive range. For perspective, Shimano’s 10-51 mountain bike cassettes have 510% range. SRAM’s 10-52 Eagle cassette has 520% range. And now you can get 530% on your gravel bike with a 10-40 cassette and simple 1x chainring. That’s really cool, but it’s the execution that makes this really something special…

Manual shifting, automatic gear selection

With just 12 cogs, Classified says you’re getting the equivalent of 15 or 16 unique gears, depending on which cassette you choose. They haven’t unveiled all of the options yet (stay tuned, they’re launching this at Eurobike and we’ll update this post with more tech details soon), but there should be gearing options that prioritize cadence and gear steps for roadies, or more range for gravel cyclists.

Because it’s all electric, and it’s all part of the same system now (as opposed to pairing a Classified hub with 3rd party derailleurs & shifters), everything can work together harmoniously, and they call this symphony of shifting QuantumShift.

With QuantumShift turned on, you can simply shift up or down and it will automatically shift the derailleur or the hub (or both) to give you the smallest gear step possible in either direction. This effectively gives you 15 to 16 individual gears.

Turn it off and you can shift through the cassette and hub manually, giving you 24 gears just like a normal 2×12 drivetrain, albeit with some duplication of gear ratios.

Eliminating the downsides

With Classified’s 2x hubs, which are widely considered a gamechanger (try one if you can), the downsides have been that you need to add a third shifter pod to your handlebar, and you need to use their proprietary modified cassettes on an otherwise SRAM, Shimano, or Campagnolo group.

Now, they have a complete system that takes advantage of TRP’s existing HyWire-style electronic shifters and proven hydraulic braking, same as what’s used with Pinion’s electronic shifting gearbox system. This gives you a familiar set of controls, with shifter paddles in all the usual places.

It also gives you the aerodynamic advantages of a 1x chainring, and lets you quickly change chainring size based on course conditions. Chainline can be better, and you can use a more efficient larger chainring up front since the hub’s easier gear acts like a small chainring.

Two cranksets are offered – the Classified aero chainset with solid chainring, or the Vistar crankset with lighter direct-mount chainrings.

You’ll still need to use their wheels, or have their hub built with your favorite rims and spokes. There are a lot of brands on board offering Classified-compatible wheelsets, though, and I imagine options will continue to expand with this announcement.

This doesn’t mention a downside for me (and I imagine others) that seems blatantly obvious: wheel interchangeability. If you switch wheels around as a lot of people do with gravel bikes, especially if you use yours on both road and gravel as certain bikes are explicitly marketed to do (e.g. Vitus Venon), you’re locked into the rear wheel that uses the classified hub.

What’s the difference between having 2x XDR wheel sets or having 2x Classified wheel sets?

Price. Much more expensive.

This true, but at least the mechanical bits of the hub are separate from the hub shell. You can buy a second wheel set with just the classified hub shell, an transfer the mechanical shifty stuff from the first hub over.

I currently have a pair of Classified Powershift wheels on my gravel bike and use it in combination with a SRAM AXS groupset. I often switch out the wheels for normal, regular 12speed wheels without a Classified Powershift hub. Why would you be “locked into the rear wheel that uses the Classified hub”?
It states that the TRP rear derailleur can be used regularly, so without QuantumShift as they call it. So I see no problems why you wouldn’t be able to use a different set of wheels, you’ll just have a regular 1x system at that point with the 12speed gearing you have on that other wheel.

This is definitely for people that have more than one wheel or are happy with one. They will sell you a hub without the internals to lace to a rim for 1x though.

Roadies are slowest to adopt new technology, I’ve seen the traditionalists scoff at every bit of new gear since the mid 80’s. Maybe we should make a return to toe clips and real leather chamois.

This is a stepping stone towards a similar system for MTB. That’s the really big application use case. And since MTBs need bigger gear jumps, you can reduce the number of gears on the cassette to 9 or 10, possibly even 8. That lets you push chain lines outboard to make room for wider suspension pivots or entire linkages. Plus you get a tiny bump in efficiency and chain wear that comes with not having to cross chain. Lastly you can build hubs with wider flanges for improved spoke and rim longevity and make wheelsets that use the same spoke lengths for both wheels without making compromises in flange heights.

I don’t know about “quickly changing chainring size due to course conditions”. Chainring size affects chain length which affects shifting accuracy.

Nah, you just need to add those teeth back to the derailleur pulley to even things out.

Swapping a 36 to a 30T chainring?
Change you lower pulley from an 11T to a 17T.
Swapping a 42T down to a 32T?
Change you lower pulley from an 11T to a 1T.

How is chainline improved?

1x rings sit between where 2x rings would be. Of course that will make chain lines worse in the extreme lowest and highest gears, but better or no worse in all the other gears.

it is great that packaged that hub with TRP. I’d like to see this catch on. This is ‘1-upping’ drivetrains a bit. Besides the positives in the article, if your derailleur breaks you’d still have a 2nd gear in a pinch.

I’m looking forward to someday seeing data on the marginal gain/losses of using Classified’s planetary gear hub.

Looks like SRAM has now officially moved into the defensive position at the top of the heap. The place Shimano used to occupy. TRP has now taken SRAM’s place as the innovator/disruptor poised to eventually replace SRAM at the top of the heap.

It will be interesting to see how long SRAM is able to maintain that defensive position. I don’t expect them to maintain a reign as long as Shimano has, or Campy before them, but who really knows? It will probably come down to how quickly SRAM’s leadership will want to cash out the value of their equity shares and turn over control to either private equity or public shareholders.

Maybe the first electronic component manufacturer that offers an open OS which allows third-party modifications and has parts which can be repaired instead of becoming electronic waste will emerge.

The biggest drawback to the Classified hub is the exorbitant cost. It’s far more expensive– four figures last I checked– than an electronic front derailleur and a comparable disc hub. It’s a cool concept but not accessible to most riders. They could probably make up in volume what they might lose in unit profit if they chop the proce and scale up production. OEMs would love to include it in their models.

Those shifters look like blatant clones of Di2 ones. How are they avoiding design patents?

The biggest downside (not mentioned) with the current Classified offerings is that the low end gear range does not match a 2x setup. If you are to use an Ekar crank and their largest chainring of 44t, it does not even get close to a 2x low gear of 50×11.

50Tx11T is the high gear not the low gear. Is that what you meant? Anyway, as mentioned in other publications, this Vistar system comes with chainring sizes of 46, 48, 50, and 52.

Ekar with a 42 front ring x 9-42 cassette = 1.0x ratio (42/42) to 4.67 ratio (9/42)
Shimano 50-34 front rings x 11-34 cassette = 1.0x ratio (34/34) to 4.55 ratio (11/50)
So Ekar and Shimano share the same low gear.
But Ekar high gear is larger / faster than a “standard road” Shimano setup.

Sure Shimano has 52-36 + 53-39 options and Campag has a 44 option, but I highly doubt these options to be pertinent for most (amateurs) road cyclists. And even with 53t big ring, Ekar is still larger/faster with a 44t ring (53/11=4.82x and 44/9=4.89x).

This would make more sense with a half step system.

So you combine the downsides of internal gear hubs (torque restrictions and higher friction) with chain gearing (exposed chain&derailleur and increased wear due to dirt) without getting the benefits of either system.
