Internal hub gear producer Classified has partnered with efficiency brake specialists TRP to create a 16-speed one-by groupset. The Vistar // Powershift is out there in a 1×16 configuration for highway driving or 1×15 for gravel driving, although the “1×16” notation is a little bit deceptive; there is not a 16sp cassette, simply 16 distinctive gear ratios.
The new Vistar // Powershift groupset makes use of a 12-speed cassette paired with a Powershift hub to supply sequential shifting, robotically altering the hub gear when needed to offer 16 sequential gears. For riders on the lookout for much more gearing, it’s attainable to take full management of the shifting, theoretically permitting riders to have 24 overlapping gear ratios from a one-by drivetrain.
Shifting is electronically actuated with the shifter, derailleur, and inside hub gear all working wirelessly.
For a single chainring groupset, the manufacturers are claiming that this new collaboration provides the widest ratio of gears at 530% when fitted with a 10-40 tooth cassette.
TRP shouldn’t be new to the world of groupsets with the model already producing each the EVO 12 and EVO 7 DH mountain bike groupsets, nonetheless this collaboration with Classified marks TRP’s first transfer into the highway and gravel market.
Classified CEO Mathias Plouvier stated, “We have spent two years collaborating with TRP on this groundbreaking product and are excited to showcase the VISTAR // Powershift groupset for the primary time.”

“Both Classified and TRP share the identical strategic imaginative and prescient about pushing the boundaries of drivetrain applied sciences and we now have achieved our purpose of making a pioneering product that not solely is quick, environment friendly and sturdy but additionally provides the widest gear vary in the marketplace.”

Although TRP may not be a mainstream title within the groupset market it’s actually a model related to hydraulic disc brakes with over 35 years of expertise creating efficiency brakes. This pedigree has been purchased over to the Vistar levers with TRP claiming that, “Vistar’s progressive, ergonomically designed hoods and levers allow highly effective, one-finger braking, regardless of hand measurement.”

Aerodynamic and environment friendly
One of the important thing purported advantages of the groupset is the aerodynamic good thing about eradicating the entrance derailleur. Due to its location on the facet of the seat tube, entrance derailleurs are in direct airflow and by their very nature should not notably aerodynamic in kind. Moving to an inside hub gearing system reduces the general drag a groupset causes.
Another added good thing about utilizing a single-ring setup with a two-speed inside hub gear is the flexibility to keep up an optimised chain line for extra of the time. With a standard single-ring arrange the optimum chain line is located in the course of the cassette. For a standard double-ring configuration the optimum chain line varies relying on which chainring you might be driving in.
What the Vistar // Powershift permits is for riders to have extra gear choices across the center of the cassette, retaining the chain in a extra environment friendly place for a wider efficient unfold of ratios. This has the good thing about rising drivetrain effectivity when in comparison with a standard one-by configuration.
TRP CEO Leo Chen stated, “We’re proud to have joined forces with Classified on our first digital drop bar highway and gravel groupset.”
“Both corporations are pushed to disrupt the market with progressive, new applied sciences, and with VISTAR // Powershift, we now have delivered a singular groupset that gives top-tier two-by efficiency with all the advantages of a one-by system.”
Specifics on pricing and availability are skinny on the group nonetheless we are able to anticipate to see the groupset being made out there by the top of Q3 this yr.
