Today, U.S.-based high-end brand ENVE announced that it will not only offer rear gear hubs on the wheelsets it primarily specializes in, but also new bike models with a "rolling chassis" option.
The Powershift hub is essentially a two-speed gearbox in the rear hub that functions similarly to a conventional derailleur-and-cassette drivetrain. The first gear operates at a 1:1 ratio, while the second reduces the ratio to 1:0.686. This ratio is similar to the difference between a 50t and a 34t chainring, mimicking the action of shifting into the "little ring," but without the risk of chain drop and with the promise of weight savings and improved aerodynamics.
While the competitive use of powershift hubs is extremely limited, primarily limited to Victor Campanato and his phenomenally large chainrings, the system has gained popularity among consumers looking to add more range to their 1x setups.
At least for now, the Powershift hub is more of an aftermarket upgrade than a factory item; it is available for all wheel series except the MTB series (Foundation, G-series, and SES series).
While ENVE is not necessarily a "mainstream" bicycle brand yet, it is more noteworthy that it is now possible to purchase Classified-equipped bicycles (rolling chassis, unless you go through a dealer) that are running on the edge of the boutique. Until now, Ridley has been the only mainstream brand to ship classified-equipped bikes, so this system represents a clear move toward becoming a genuine 2x option for consumers, rather than just an aftermarket upgrade.
Prices are as follows for the Powershift hub shell wheels:
Rolling chassis are available for Melee, MOG, and the new Fray with or without hub internals and shifters, starting at €7.699/$8,000, complete at dealerships Car sales start at €10,899/$10,899.
Pricing in the UK has not yet been determined.
