Good morning,
It did intrigue me that Shimano, SRAM and Campy did nothing in this direction.
Ceramic Speed seem to be claiming a reduction in power needed when riding at around 250 watts of a bit less than 1%.
Given that this is best case I can see why the big three aren't rushing to join the fray.
Given their size Ceramic Speed can set up production runs of 500 or 1,000 units and pass the cost of such a small run onto the customer, hence the £300 price tag, or zero if you are a pro being given it.
For the big three if they offer something, they need to offer it in sufficient volumes that there won't be complaints based on the the lack of availability, but before that they need to have management meetings, loads of research and testing and then commission a production line. The downside of mass production.
Jockey wheels have always been small and most of us take it for granted that this is the correct size, so let's mock someone who suggests otherwise. Yet if they are truly a better idea then why not roll them out when the company is ready, but equally why rush as it is such a small gain?
I imagine that once you start looking at changing something that "has always been done this way" you start to question other things, should the teeth be deeper to help shifting, how much movement should there be in the bearings, should the cage flex or be totally rigid, would three wheels be better? At which point the team gets pulled off onto the core details for the 2025 version.
So I would be expecting large jockey wheels from the big boys sometime in the near future on top of the range groupsets once they work out what actually works and what is marketing hype. Even if they find no advantage it may still be worth it as a marketing exercise to imply that the other two makers are behind the times.
Bye
Ian
I only bought them when I'd run out of other things to upgrade though
