Classified enters the CF G19 as a low-profile, lightweight hookless rim wheelset. At an impressive 1,160 grams for the set, it seeks comfort over rough gravel with high compliance thanks to its low-pressure tubeless design and generous internal width. Combined with the Classified Powershift system, users will have a lightweight, modernly wide gravel wheelset to choose from. \

According to the company, rider feedback informed the new design.
“We developed the G19 to meet the needs of gravel cyclists worldwide that expressed their desire to have a lower profile gravel wheel that gives them great compliance and improved comfort,” said Mathias Plouvier, CEO of Classified.
It’s also compatible with Classified’s Powershift hub, which bypasses a front derailleur but doubles any compatible bike’s gearing. First released as highly proprietary, the internally-geared hub can now give most riders a more comprehensive gear range thanks to the G19 and its three previous cousins, the G30 and (road) R35 and R50. The wireless setup helps riders shift fast when standing still or pedaling hard, up to a power output of over 1,000 watts.

The Classified CF G19 wheelset is disc brake-ready and uses 24 spokes. The optional Powershift hub works with SRAM or Classified’s own 11 or 12-speed cassettes and 11-speed Shimano rigs. While Classified has confirmed the G19 launch, it has not yet released pricing details.

“up to a power output of over 1,000 watts.” I would think torque would be a factor more than power. Does anyone know the rationale for this limit?
I’m guessing it’s because people understand what their power output is. Torque meters aren’t standard last I checked.

Maybe someone can explain these to me, but why would one of these hubs be better than just an internal hub with all the gearing inside and a 1 speed chain set up or just having a front derailleur and not the proprietary Bluetooth hub, cassette etc. I get the idea of making things simpler but these always seem to be more complicated. In a TT a single speed arraignment would be very aerodynamic in comparison with a rear derailleur and for big time off roading it seems Rohloffs are preferred by bike tourers in adverse conditions.
Internally geared hubs, are heavy, mecahically complicated, and tend to loose a lot of efficiency in their gear arrangements.
So they are selling this with the power shift hub shell but not the gearing? Will they sell you the guts at a later date of you chose?
I think these hubs/ wheels are a great idea. You can have more range than just about any 2x system without the hassle of running a front derailleur. What 2x system is compatible with a 10-52 cassette? think of the possibilities
I’ll eat my shoe if the set weighs 1,160 grams as stated in the article.
The rear wheel only incorporates rhe rear hub’s shell. No bearings, no axle, no freehub mechanism, and in this case also no internal gear box.
