Inner hub gear producer Categorised has partnered with efficiency brake specialists TRP to create a 16-speed one-by groupset. The Vistar // Powershift is offered 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 brand new Vistar // Powershift groupset makes use of a 12-speed cassette paired with a Powershift hub to supply sequential shifting, mechanically altering the hub gear when mandatory 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 inner hub gear all working wirelessly.
For a single chainring groupset, the manufacturers are claiming that this new collaboration gives the widest ratio of gears at 530% when fitted with a 10-40 tooth cassette.
TRP isn’t new to the world of groupsets with the model already producing each the EVO 12 and EVO 7 DH mountain bike groupsets, nevertheless this collaboration with Categorised marks TRP’s first transfer into the highway and gravel market.
Categorised CEO Mathias Plouvier mentioned, “We’ve got spent two years collaborating with TRP on this groundbreaking product and are excited to showcase the VISTAR // Powershift groupset for the primary time.”

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

Though TRP may not be a mainstream title within the groupset market it’s definitely 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, no matter hand dimension.”

Aerodynamic and environment friendly
One of many key purported advantages of the groupset is the aerodynamic good thing about eradicating the entrance derailleur. Resulting from its location on the aspect of the seat tube, entrance derailleurs are in direct airflow and by their very nature will not be notably aerodynamic in type. Shifting to an inner hub gearing system reduces the general drag a groupset causes.
One other added good thing about utilizing a single-ring setup with a two-speed inner hub gear is the flexibility to keep up an optimised chain line for extra of the time. With a conventional single-ring arrange the optimum chain line is located in the course of the cassette. For a conventional 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, protecting the chain in a extra environment friendly place for a wider efficient unfold of ratios. This has the good thing about growing drivetrain effectivity when in comparison with a conventional one-by configuration.
TRP CEO Leo Chen mentioned, “We’re proud to have joined forces with Categorised on our first digital drop bar highway and gravel groupset.”
“Each 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 nevertheless we are able to count on to see the groupset being made obtainable by the tip of Q3 this yr.
