Classified - the innovative Belgium drivetrain brand renowned for its two-speed integrated rear hub - is finally ready to release it's own groupset.
The 'Vistar Powershift' groupset is a collaboration between the hub gear box company and Taiwanese component manufacturer TRP (Tektro Racing Products). The one-by groupset was first spotted in testing at Unbound last year and promised better chainlines and sequential shifting across a 12 or 13 speed cassette.
