Last years premium mechanical mountain bike drivetrain was just a warmup to TRPs big drivetrain ambitions, and now, along with Classified, theyre 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 Classifieds two-speed internally geared hubs, they achieve a wider range of unique gears up to 530% range with an 11-40 cassette.Thats massive range. For perspective, Shimanos 10-51 mountain bike cassettes have 510% range. SRAMs 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. Thats really cool, but its the execution that makes this really something specialManual shifting, automatic gear selectionWith just 12 cogs, Classified says youre getting the equivalent of 15 or 16 unique gears, depending on which cassette you choose. They havent unveiled all of the options yet (stay tuned, theyre launching this at Eurobike and well 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 its all electric, and its 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 212 drivetrain, albeit with some duplication of gear ratios.Eliminating the downsidesWith Classifieds 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 TRPs existing HyWire-style electronic shifters and proven hydraulic braking, same as whats used with Pinions 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 hubs 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.Youll 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.Classified-Cycling.ccThe post TRP x Classified Launch Vistar Wireless 116 Drivetrain! appeared first on Bikerumor.
