CyclingCeramic adds a Shimano 12 speed Di2-ready option to their carbon ODC oversized derailleur cage upgrade kits, on top of SRAM 12sp compatibility. Now you can get their latest 14/19T pulley wheel combination to reduce drivetrain drag on pretty much all of the last two generations of Shimano & SRAM road groupsets.

The made-in-France CyclingCeramic ODC oversized derailleur cages promise to upgrade your drivetrain by decreasing friction by up to 98% (an obviously semi-dubious claim that appears to be benchmarked against a Shimano Acera pulley wheel setup). Taking that claim with a grain of salt, larger pulley wheels, less chain tension, and ceramic bearings have been demonstrated to lower drivetrain friction.

CyclingCeramic’s latest oversized derailleur cage upgrade kits now feature a larger 14T/19T pulley wheel combination (vs. the original 16/16T combo) that is said to further reduce friction by decreasing the angle of the bend your chain makes snaking through the rear derailleur while improving shift quality.

Like many other companies peddling oversized derailleur pulley upgrades and ceramic bearings, CyclingCeramic calls their ODC a #FreeSpeed upgrade, albeit an expensive one. With Grade 3 ceramic ball bearings inside steel races and machined carbon side plates, CyclingCeramic says their oversized pulley upgrades have been independently verified by Friction Facts to have the “lowest level of friction with only 0.03 watt”.

The latest ODC kit for Shimano 12 Speed Road setup sells for 350€ and features titanium bolts and machined alloy pulley wheels available in black, gold, green, red, or blue ano. The CyclingCeramic ODC 14/19T upgrade kit is now available for Shimano 8000, 8050, 8150, 9100, 9150 & 9200 derailleurs and SRAM Red AXS, Force AXS & Red eTap derailleurs.

UPDATE: CyclingCeramic now adds an OCS 14/19T upgrade for SRAM Rival AXS, although curiously it appears to now be the same part as the previous Red AXS/Force AXS ODC.

A recent CyclingCeramic ODC compatibility chart also references ODC 14/19T Gravel models for both Shimano GRX and SRAM mechanical 1×11 groups, so perhaps those are coming soon, too!

You can tell someone is moronic buffoon on when you see oversized pulley wheels on their bike. Shimano’s budget for toilet paper is many times what Ceramic Speed spends on R&D, if oversized pulley wheels made any difference, they would come stock on Dura Ace. No matter what stupid lies the bike industry spews, there are consumers that will buy both the lies and the products.

You seem to have forgotten Shimano engineers also need to hit a price point when dealing with OE and the consumer. They also need to produce 10s of thousands consistently, and believe it or not something as simple as two different pulleys not only ads sku’s but possibility or being put together wrong.

Ceramic Speed does not have such worries due to targeted clientele and small batch production

Shimano’s two pulley wheels are already different from each other.

They’re different from one another but they don’t wanna make 2 more different pulleys and potentially a new cage. You can go slightly bigger with the stock cage but not these cages

If someone can afford it why not. My bike stock with Dura-ace and all the latest in tech but don’t give a shit about whether it helps me with my cycling. I’m not an Athlete, probably a Moronic buffoon like you said, but what I do with my money, is my business. Maybe at the same time, inevitably make a few people mald over the assumption that people want it for the gains. That shit is pointless and most of us know it, but we still want to splurge our money. Its boys with their toys, deal with it.

larger pulley size reduces friction just like larger wheel size, and ceramics increase the effect, not 9th are u wrong, but your attitude is not very constructive

Dura Ace doesn’t have them because Shimano isn’t interested in the biggest gains. They want reliability with the best profit margins. The bulk of why high end ceramic bearings are faster is that they normally also come with low contact seals that need more maintenance. The issue with oversized derailleurs pulleys is that you lose about half of the drivetrain gains through aerodynamic losses unless you’re talking a mountain bike or a bike mostly ridden in a peloton

Wouldn’t the weight of the extra links in the chain required to cater for the extra chain length required cancel out any friction gains?

It is also less aero

Weight affects riding speed surprisingly little. The weight of a few links is insignificant.

True, true. And so is the pulley

Nope, but the aerodynamic drag of the bigger cage cancels most of the gains. The aero cage from ceramic speed cut a friend’s drag by 2w in the wind tunnel over his non-aero oversized caged though. That’s pretty sizeable

Will i be the coolest guy on the group ride with these? Will overall performance, shifting, and reliability be worse than stock??

Performance is better in terms of friction. It definitely needs more servicing though

I bought a similar device for my Ultegra mech, it was a made in China generic gadget and at $70Au it did make a discernible deference and looked fabulous. I bought it because it turned my short cage into a medium cage at 1/4 the price of changing the mech. Bargain.

Hopefully your bearings are sealed. Some of them aren’t sealed at all. That said, the difference can’t be felt but can be measured

I don’t see any comments on shifting yet, so here’s one to ponder: shifting precision is highly dependent on alignment. This means the two important characteristics for a jockey cage and wheels are the size (radius) of the wheels and the quality of the bearing. Assuming the bearings are of equal quality, then the bigger radius will allow more ‘slop’ in aligning the upper jockey wheel to the cassette cogs. So, what is the basis for the claim of better shifting as a result of a bigger jockey wheel? I see no problem for the larger lower wheel..
