Oversized pulley wheel systems - are they worth it?

The first advantage is that you are lighter because your wallet is less heavy

I have used novaride on my Ultegra and found the shifting not as snappy as the stock pulley. Also, the drivetrain became noisier which was a put off. It did feel smoother although that may be a placebo effect. I instantly went back to the stock pulley. Sometimes the cons of fitting an aftermarket product to the drivetrain may outweigh the benefits. Sharing my two cents worth.

How odd is that I was just researching this yesterday. And then this video comes out today!

Most people won’t pony up this kind of money for ceramic components. And they don’t really need to. We know Quality is not linear with price. I paid the price and it opened my eyes up to “ceramic specialness”. For me the ride quality is absolutely sublime/perceptible when combined with bottom bracket and hub bearings. I went with CermicSpeed OS Pulleys and Bottom bracket. Chris King ceramic hubs on my Moots, Red AXS 2X, Enve 3.4. I buy the best gear for me and extrapolate and expect the best in performance. I feel without question I got it. Life’s short. That’s all that matters to me. You do what’s best for you. Ride safe and ride often. Peace.

They increase the derailleur capacity which is enough reason to use them if you need more capacity for some experiments with cranksets.

can you list the names of the 2 pullys you show here . the frence one , i can't find it online . tnx

Hi Ronald, would you recommend this to just an average rider?

Think of what matter most, it's the reduced chain articulation. Tripeak has 12t top, 14t lower pulley which cost less than $100. Those fit into original Shimano cage and don't degrade the shifting quality.

They don’t work, larger wheels means more Chain to wheel contact with increases friction and at speeds over 35kph, more drag due to aerodynamic actually makes you slower. Do don’t waste your money!!!!!!!!

interesting video. With oversized pulley wheels, do you need to use a longer chain?

Hi, what was the name of the third option, the French brand, I didn't quite catch it. P

But how do you replace the original one with the aftermarket one ?

You should actually test each one versus regular pulleys. You have them all and are a mechanic, so changing between them should be easy. Dual recordings with power pedals and a smart trainer, keeping everything else on the bike the same.

Hmm... with larger pulley wheels the chain bends less but there are more chain links to bend so I wonder if this makes a difference. Less spining resistance in bearings can result in improved drive train efficiency if this can be sustained in bad weather conditions (bearings' sealings?).

Yes any links and pricing on the two , with thanks Dan

How does it change the ride? I am a weekend rider, if I did spend the big money and buy one, how would change my overall ride?

Hi Ronald Kuba, nice video; please could you add the links for the 2nd and 3rd OSPW systems? Thanks,

what about the new absolute black ones with the futuristic hole?

all for a power saving of 0.24watts?

I changed out my 11T 105 bottom RD pulley with a cheap 13T sealed NTN bearing pulley and found the drivetrain to be slightly smoother right away. 105 pulley is spun on bushing. Maybe that is why it felt slightly better. With Ultegra and Dura-ace RD, I'm not sure if you can feel any difference whatsoever. So for a 10 dollar ( about 4 for the pulley, 6 for the bearing ) upgrade, worth every penny IMHO. But if i had to pay >100 dollars for it, definitely not worth it.
