Patent patrol: Campy filed a patent to enable 10t small cogs
Courtesy of Bike Rumor: Campagnolo filed a patent for a new freehub/driver design. Quoting from the article:

Also discussed in the article: Shimano filed a patent for a gearbox. SRAM filed patents for some improvements to its shift ramps. Last edited by weiwentg; 11-12-2019 at 10:10 AM. |

Can someone smarter than me explain why that's not just a SRAM XD cassette?

I think it would be similar to SRAM but campy needs to have its own patent in order to maintain its market share and drive up sales of its own campy cassettes.
This doesnt provide any real value add to the bike industry as a whole and probably is marginally better than what campy already has. This would likely necessitate the need to get a new camp freehub as well which would probably be bad news for current campy owners. |

Form the photos, it appears that existing rear hubs can be retrofitted with the new freehub body. But the drawings seem to indicate that the sprocket "dome" is attached from the back side. For standard spoked wheels, the spider attachment points might be accessed through the spokes from the non-drive side. But this wouldn't be possible if used on a disc wheel. Another concern is that permanently attaching the spider arms to the freehub body limits the range of sizes of sprocket "domes" that can be used. But this might not be of much concern to Campagnolo, as the range of gearing sizes available for each drive train is becoming more and more limited by the manufacturers. |

Fastener in a cassette?? Is that even durable? I dont know, the idea looks ok to me but the thing is... it is practical?
The other thing, to me looks a lot simpler just put that 10T cog and the 11 cog together in one block and make it work like the lock ring?? Just need a smaller lock ring tool but besides that looks a lot simpler than re invent the whole concept. A lot of patents moving around which contain stuff that cant even be used in real world situations, this one looks like one of those. |

There's really no way to fit a 10 tooth sprocket onto a Campagnolo freehub without a substantial redesign. |

Looks like a workaround to avoid stepping on SRAMs XD/XDR toes.

it sucks that at one point we could share cassettes btw all systems and now with 12 speed it is all going to crap

Maybe a reason to stock up on 11 speed stuff. |

This could be related to the Campagnolo gravel group coming out in the near future...

The Chorus 12 crankset has four extra bolts that seem to do nothing... I wonder if they're there as a placeholder for a 1x chainring.

The Gravel trend is really strong and Im guessing they dont want to miss out this time like they did at first with discs

As has been mentioned, Campagnolo has a sub compact crank, mid cage rear dear, disc brakes......etc... I don't think 1by is an essential except that marketed by one manufacturer. Cross racing, I can see it but GRoad bikes, 'gravel grinders', dirt road enthusiasts? Don't see it as essential, 1by...what about riding on dirt roads makes 1by essential vs a great working double with closer ratio rear cluster..same lower gear, higher high gear?

I believe the commuter, non informed cyclist, is the right target for all the industry. A bicycle is a transportation vehicle. The best there is. The future belongs to bicycles. I am ok w/ the mass audience... just don´t sell me mass production angles as performance enhancing technology. It´s BS. By the way... gravel bikes are the new mountain bikes: same angles and capability. A 650B wheeled, disc brake, late 80s mountain bike. Have a good day. |
