Are Shimano and SRAM finally facing serious competition? With the Vistar Powershift, TRP are launching an electronic groupset for both road and gravel that aims to ruffle a few feathers. Thanks to the 2-speed Classified hub and impressively crisp shifting, its taking the fight straight to the established heavyweights. Weve put the newcomer through a proper trial by fire. The real question is: does it have the legs to earn its place in the peloton?TRP Vistar Powershift | 1,525 | Manufacturers websiteIs the groupset market already saturated? Ask Shimano and SRAM and they would probably say yes. At Tektro Racing Products, or TRP for short, the fun is only just beginning. The Taiwanese manufacturer has built its reputation on braking performance, primarily in the MTB world. Now TRP are entering new territory. The Vistar is offered in combination with Classifieds two-speed Powershift hub and arrives as a bold newcomer, ready to shake up the established road and gravel drivetrains. The promise is ambitious. Combine the simplicity of a 1x setup with the range and tight gear steps of a 2x system, and make the whole thing electronic.Up close: ergonomic brilliance with a few minor misstepsFirst impressions? Premium. The glossy black finish paired with the dark anthracite rear derailleur looks superb and wouldnt be out of place alongside a Shimano Ultegra groupset. Then your eyes move to the hoods, and things get interesting. Here TRP break with convention, opting for a distinctive industrial aesthetic. The mix of matte contact surfaces, gloss levers and textured details gives the control unit the feel of a finely engineered motorsport tool. Its bold, purposeful and refreshingly different. Glance down at the chainring, however, and that polished picture loses a touch of its shine. Compared to the rest of the groupset, it looks almost like an afterthought, more aftermarket add-on than integral design element. It doesnt quite harmonise with the otherwise cohesive look. Still, as we all know, its whats going on beneath the surface that counts when youre battling along a gravel track or pushing hard on tarmac.Now to the business end: the levers. TRP have clearly done their homework when it comes to materials and build quality. Nothing rattles, nothing creaks. The shifters and brake levers feel rock solid and inspire confidence from the first squeeze. Hood ergonomics are well judged. At the rear they are broad, offering a generous platform for the heel of your hand. Towards the front they taper noticeably, echoing the shape of Shimanos hoods. That slimmer profile makes them easy to wrap your thumb and fingers around, a real advantage when the terrain turns rough and unpredictable. Combined with the grippy rubber surface, you get excellent control whether you are cruising along or launching a perfectly timed attack.With TRPs Vistar Powershift, your attack hits with impeccable timing.The shifting logic closely mirrors Shimanos Di2 system. If youre already familiar with Di2, you can jump straight on and feel at home. TRP go one better with the actual buttons. Theyre clearly separated and feature distinct textures, so you can tell them apart by feel alone, even with chunky winter gloves. The bite point is satisfyingly crisp, delivering a clear mechanical click as feedback. That said, you do have to press the buttons fairly deep to trigger the shift.A well-judged mix of materials, convincing ergonomics and clearly defined shift buttons. We are genuinely impressed with the Vistar hoods.Out on the road, the Vistar rear derailleur impresses with its precision. Shifts are quick and remain almost silent, even under full load. On rough surfaces such as cobbles, the chain stays composed at speed and refuses to bounce around.TRP call the pairing of the Vistar with the Classified Powershift hub QuantumShift. The two-speed hub is seamlessly integrated into the Vistar ecosystem, creating a cleverly coordinated system rather than a bolt-on solution. In the road setup, this configuration effectively simulates 16 distinct gears by intelligently factoring the hub ratio into the shift sequence. When shifting up the cassette into smaller sprockets, the chain jumps from the eighth back to the fifth sprocket while the hub simultaneously shifts from its lower to its higher ratio. Because the hub changes gear without interrupting drive, unlike a traditional front derailleur, the whole process happens subtly in the background. You barely notice it. In the gravel setup, you get 15 gears due to the larger jumps between sprockets. Automatic front shifting is nothing new and other electronic groupsets offer similar functionality. However, the integration of the Powershift hub is particularly well executed. The fact that theres no interruption in power transfer makes it a genuine comfort feature. As a welcome bonus, running a 1x setup virtually eliminates the risk of dropping the chain at the front.The Classified Powershift hub is both visually and technically well integrated.For the gravel setup, you can choose between 44, 46 and 48-tooth chainrings, each of which can be paired with two cassette options. The 12-speed cassettes come in 1134 or 1140 configurations. The road setup offers a choice of 50 or 52 teeth at the front, combined with three cassette options. Here too, the 12-speed cassettes start with an 11-tooth sprocket and run to 30, 32 or 34 teeth.Add the Powershift hub into the equation, with its 1:1 and 0.7 ratios, and the gravel setup delivers a massive gear range of almost 520%, precisely 519.48%. Following TRPs gravel and road classification, the road setup offers 442%. That said, theres nothing to stop you mixing and matching chainrings and cassettes, so you can unlock the wider range even with the larger road chainrings. The package is rounded off with crank lengths of 165 mm, 170 mm, 172.5 mm and 175 mm.Braking performance is beyond reproach. Admittedly, we would expect nothing less from TRP, given their expertise in braking systems. The bite point and modulation are so refined that you would never guess this is their first dedicated drop-bar groupset. However, where there is light, there is a little shade. If you prefer braking from the hoods, you will notice that the Vistar requires slightly more hand force than Shimanos GRX.The powerful brake calipers keep a low profile and let their performance do the talking.In our test, the app connectivity proved slightly temperamental. While the connection to the hub was established quickly and remained stable, the rear derailleur was a little more reluctant to play along. One real highlight, however, is the battery management on the rear derailleur. The battery is neatly tucked away beneath a sturdy cover, yet can be removed in seconds without any fiddling. Thats a genuinely smart solution and one that other brands could learn from. The Classified hub takes a different approach. Its battery and control electronics are housed inside the lever of the thru-axle. It is a tidy bit of integration, but it does raise one question: how robust is the system if the bike takes a hit on that lever in a crash?Open the cover, pop the battery in, close it up. That is how battery management should be done.Serious competition from the second rowAt no point does the TRP Vistar with Classified integration feel like a first attempt at a drop-bar groupset. Instead, it arrives fully formed as a genuine rival to the established heavyweights. On our ride, it impressed with superb tactility, intuitive operation thanks to QuantumShift and shift speeds that have nothing to fear from the big names. Paired with the seamlessly integrated Classified hub, the Vistar stands out as a striking new contender in the fiercely competitive groupset market.Pricing also shakes things up. The groupset without the Classified Powershift hub retails at 1,525. At first glance, that looks like an attractive price. However, the cassettes require the dedicated Powershift freehub body, which does take the edge off the apparent saving. For the complete Classified system of axle, hub and internal unit, the recommended retail price is 1,400.The TRP Vistar Powershift marks a successful debut in the world of electronic drop-bar groupsets.Who is the TRP Vistar Powershift for?The TRP Vistar is a distinctive, high-performance electronic groupset and a clear statement of intent aimed at the established market leaders. If you appreciate Shimanos shift logic and are looking for a system that feels premium in your hands while making a bold visual statement, this could be right up your street. The Vistar stands out with outstanding button feedback and a level of build quality that easily holds its own against the big players. It is ideal if you love the clean look of a 1x setup but do not want to sacrifice the gear range of a 2x drivetrain. The trade-off is that your choice of wheels becomes significantly more limited due to the Classified system.Conclusions about the TRP Vistar Powershift groupsetThe Vistar injects fresh energy into the groupset market, impressing with crisp shifting, seamless integration of the Classified hub and superb braking performance, clearly benefiting from TRPs long-standing MTB expertise. That said, the tie-in with Classified does push up the overall cost and inevitably limits your wheel options. Even so, if you are after the clean look of a 1x setup combined with genuine 2x range, this is a technically innovative package that can go toe to toe with Shimano and SRAM without blinking.TopsConvincing shifting and braking performanceClear tactile feedback and a well-defined bite point from the shift buttonsFlopsCassettes require the dedicated Powershift freehub bodyTo find out more, visit trpcycling.comDer Beitrag TRP Vistar Powershift On Review: Attack From The Slipstream? erschien zuerst auf GRAN FONDO Cycling Magazine.
