Just started looking at these as an option, and was shocked at how expensive they are. Are they worth the price? Is it a noticable upgrade? Thanks

"Worth the price" is VERY relative
But Yes; If you have look at everything else (helmet, skinsuit, tire, tire pressure, wheels, clean chain, transition time, position, etc.) and you think $500 for 1-2 min on an IM is good value.

Having owned a Ceramic Speed cage I wouldn't buy one for the price. The cage is actually made out of some kind of plastic not carbon and it shattered on me. I would source one of the other brands out there with a aluminium or carbon cage. Minimal gains so depends if you have the $$$...

I wouldn't give it even a moment's consideration personally. Immediate no.

I have an oversized pulley system with really nice bearings that I bought for less than $100. I don't know that it really makes a big difference but no way would I buy a Ceramicspeed pulley as the gains at best are minimal from what I've gathered.

I bought a Premier Bike OSPS. This post reminds me that I need to install it. I believe they are an improvement over standard pulleys, but there is probably little to no additional incremental value of a Ceramic Speed over many of the other options.

same here, Ceramic Speed coated bearing pulleys and Premier chain....need to install.

Anyone know anything about the aerodynamic drag of the oversized pulley? Even if you save 1-2w from friction, having it -1-2w as an aero penalty really defeats the purpose of it.

We have started selling the ceramic wheels that are direct fit on Shimano cages. They are super easy to install, no flexing of the long cages, no long cage hanging down in the wind and cost less.
We found that some athletes were having trouble installing the full cage.
I think the wheels are a good compromise between performance, aero drag and cost.

Very optimistic indeed. What you get in friction reduction you will lose back in aerodynamic drag from the larger pulley wheels and longer derailleur cage. The faster you travel, the more watts you will give up to aero drag since friction is linear but air resistance is quadratic. I'm very interested to find out where the cross over point is.

Hey Dan,
Would the wheels fit with Ultegra 6800?

They do not. The wheels fit DA-91xx, UL-R80xx and R70xx series.

Of course it's worth $500 to gain a fraction of a watt. I also think a stack of $100 bills creates a good spacer for my TT bars. On a serious note, I've thought about, but then I imagine the hypothetical conversation with my wife, and I think better of it.

I would do the BB first. I swapped out a steel BB for Sram Black Box, then my cycling instantly improved. For the first time, I had faster splits than guys I had no right beating, with no more training. It was a huge difference, so I'm not buying that gains are "marginal" with the BB, it's significant.

Phil Wood "carbonyte" bearings are just as fast as ceramic and they are steel.
You be the judge...

If you like spending the money then you go for it. I went back to steel based on I found no difference, they last a lot longer and they are a lot cheaper...
