    Default CeramicSpeed Pulley

    I am in no way implying that this is a scam item. I am just trying to imagine a world in which a $500 derailleur pulley would be ... real? Iíve never seen one on a bike, I canít imagine putting one on a bike, and I definitely canít imagine buying one. But chapeau to CeramicSpeed as they have done a really good job getting them out there on pro bikes and marketing them to people. Enough that when I got a blurb email from Excel Sports on them, I clicked and had a look, rather than what I usually do (look and delete.) I havenít unsubscribed from Excel because they have not infrequent tire and tube sales that I use to keep up stock at home, so this isnít a complaint, but in a way, I feel like the velvet-boxed Astro-Daimler bike with gold Campy that sat on the wall of my childhood bike shop has become a CeramicSpeed pulley and while that is far less desireable and romantic, it is just as imaginary as the AD and its purple velvet (that I couldnít reach to touch) was back then.

    The cheapest bearing Ceramic Speed sells (as of a week ago when I looked at their website) is $95.

    For a bearing.

    One bearing.

    $95.

    For one.

    Same company that sells $75 chain lube, no? Which apparently yields 10 applications. I've had these 2 tiny bottles of NFS for almost 5 years. They're about 1/3 full...maybe I just don't ride enough Į\_(ツ)_/Į

    I prefer bog-standard pulleys. As a matter of fact, I go out of my way to abuse them---no cleaning, and no lube. I find that at the end of the summer cycling season, I am in better physical condition, and perhaps in the end, I am a better human being.

    I've seen a few of them in the wild. This is the kind of product you see almsot exclusively in sportive events. The more expensive these events are, the most chance you'll get to see them.

    I will say that I'm surprised the major manufacturers haven't jumped on this with their flagship lines, like Dura Ace and Super Record and Red. Whether or not it actually improves efficiency is not known to me but it seems like it would be good marketing.

    Aftermarket pulleys have existed since I started riding. You could always tell who had the aftermarket ones because they were loud because they were metal. I'm not sure I like metal pulleys for this reason alone and I can't imagine having one of these and having it wear out. Looks kind of delicate.

    Shimano has. Not sure why the pro peloton hasn't just snapped them up.

    A friend of mine got one on his SR group. This is the item you buy when you have exhausted every other item to buy.

    And it won’t do any good if the drivetrain isn’t perfectly clean.

    Suntour pulleys from back in the day. They were plastic and contained sealed bearings.

    I seen them in the neighborhood. I also seen a Bugatti Chiron going to the grocery store. I own a CS bottom bracket. It is nicer than the rest (Kogel quite possibly being equal).

    The hot setup in the early 90's was a Shimano Light Action rear derailleur with Bullseye pulleys. I had a short cage one on my MTB for several years with XT thumb shifters.
    I heart burnt bikes.

    it improves drivetrain efficiency. it also directly hurts shifting performance and leaves you with a derailleur more likely to get snagged on something.

    the takeaways I got from the friction facts papers was that there are marginal gains to be had from running the longer cage and giant pulleys, like 2 watts. You have to be otherwise perfect to see that though.

    I've got the KCNC pulleys on my Zukas RD. They didn't cost hundreds of dollars, aren't oversized w/a special cage, and they do seem to spin better. Can't say it actually makes a difference out on the gravel road tho...

    I think I had a set of these at one point on something. They were awesome.

    Too bad Suntour (the Suntour from the 1970s and 1980s, not the reincarnated name on some low-end products) didn't survive. They made some really nice stuff and I always loved their brakes with the internal return spring. Made for a much cleaner design.

    I had them, purple bullseye pulleys, then they seized in a late season race, tore the derailleur off... ugh.. xt thumbshifters with the "ghost" 8th click, campy centaur freehub, still have it/them somwhere

    We were using the Light Action with Bullseye because the XT short cage derailleurs were snapping off. There was all kinds of road bike cross over stuff back then. I think the cassette was a 12-28 seven speed with something like a 26-36-46 front triple. Never had a Bullseye fail but they made the drivetrain sound like a sewing machine.

    Think the Ceramic Speed pulleys are bigger than his cassette.

    Speed costs money, Ceramic Speed will gladly sell you some. Or you can keep on moving, they won't loose any sleep over it.
