@@mrskeltal3281 you are adding additional length to the path the chain has to move to complete a revolution, so yeah, you should add a link or two more if your new cage is longer and if your chain was properly sized before
Yeah, good obervation! So the chain I'm running was sized with an 11-28 cassette and the regular medium derailleur cage. With an 11-28 cassette, the new oversize cage works great, but I recently upgraded to an 11-32 cassette which I fitted a few days ago.

Got one of those on my DI2 Ultegra for a couple of months now, absolutely flawless function I must say. However, 2 things you should do: 1. Replace the bearings once fall is getting close. As you mentioned, the stock ones are not going to survive long in wet conditions. Packing them with grease may help a while, but ultimately, a set of proper SKS bearings will cost you about 15€, so what the hell. 2. While you‘re replacing bearings, make sure you add some Locktite to the screws putting the cage back together. Otherwise, those tend to come lose und suddenly you got a little bit of a problem.

4:14 I was thinking: are you able to just take the seal off of the regular bearings and put it on the ceramic ones? That way not only do you have the benefit of low-friction ceramic bearings, but you also have protection against mud and grinds with the seals.
@Herman Copelin I have, with great results, might I add. My personal use was for a longboard I built 4 years ago. I found that ceramic bearings marketed towards skaters were overpriced and no difference other than the plastic case/seal. I took the seals off a set of cheap steel bearings, ordered a set of ceramic bearings from aliexpress, and they fit in perfectly.
@@THSimagery Just make sure the bearings you buy are rated for an application similar to your use. In other words, don't use rc car bearings on your bike lol 😉
Loving your work sir. Laughed out loud about your observation that, "If I was a professional rider, I probably wouldn't have chosen the cheapest wheels, bottom bracket and bearings that I could possibly find!".
I have to be honest. In the beginning I've founded this guy annoying. But after I subscribed and watching more and more of the videos I realized that "As Always Luke" is funny man..lol 😂 thnkx for the video 💪🏾
Thanks for the tips, from my R7000 105, I changed the plastic rollers with the ultegra rollers, they have bearings . I gain 1,5 watts 🙂🙃🙂🙃 with 10 pounds cost.
I had a kcnc oversized pulley, it was such a pain to get it set correctly and even then never shifted correctly, the shaft was not designed to spec of the Ultegra part it replaced, it either was too tight and didn't move easily, or was too loose which effeced shifting
Hey Luke, love your channel. I am running a KCNC OSPW on an R6800 and I just picked up one like this carbon one for an R8000 derailleur. My chain length is correct for the OSP but my question is can I run an 11-34 cassette now because it makes the cage much longer than the OEM SS cage? Or do I need a goat link to give the derailleur the drop? Just curious what the largest gear you can run with these OSPW. Thanks! Cheers!!
I answered my own question and just to give you a update on what I found. I put an OSPW on an R8000 Ultegra derailleur and one of those aluminum 11-34 cassettes that you have tried and had great success! The B screw is almost all in but it does shift beautifully and I get the larger gear range with the OSPW without an extended link. I hope that helps anyone out there that wants to try this combination! Cheers!
It's very likely the 2.5W gains are even less than claimed, I've not seen the test setup they use but the whole 'chain turning in tighter circles' thing is correct, but it's very dependant on the actual tension in the chain for these losses to actually be meaningful. If you press down on the pedal slightly with your rear brake on, you can still pick the chain off the underside of the cassette/chainring. The tension here is only provided by the derailleur cage torsion spring. So minimal tension in the chain, so minimal losses from the chain friction (minimal is orders of magnitude lower than 2.5W). Chain tension is a thing from 9-12 o'clock on the cassette and the opposite on the chainring. Bearing drag isn't really a thing that can be reduced that much on bikes due to the speeds involved, the difference in rotational speed between the jockey wheels is minimal and the drag is already low. Most of the test data and research for this thing is focused on gearboxes with speeds in the 1k+ rpm. And I'll leave you with some food for thought.... If chain tension losses from tight circles are a thing (which they are, elite track cyclists use 16T+ cogs for a reason), then why is there a push to use 9T and 10T cassettes on 1x systems, it doesn't make sense!
Please Luke may try using the metallic bearing's seals and put them on the ceramic ones to see if they make the job of sealing completely the bearings!?
Hey @trace velo love the channel. Just wondering, as the ceramic and aluminium bearings are the same size, could you harvest the seals from the aluminium and put them on the ceramic?
Yeah its probably going to be a while until I do a dedicated update on the EliteWheels, but so far so good. Admittedly ive only done a few hundrerd miles on them, but still perfoming great!
An informative and entertaining video again. When you were demonstrating the gear shifting on the trainer, it looks as though you need to do a few extra links in your chain. Did you put any more links in to compensate for the larger jockey wheels?
Yeah great question. So I actually tried this, and it totally doesn't work. I think the diameter of the ceramic bearings are slightly larger that the regular steel ones, so adding the seals completely jams up the ceramic bearings unfortunately.
If someone is curious why they dont add bearing covers -> the covers are the main reason for friction/power loss. I would say you lose more with bad fitted covers instead of that what you get from the ceramic bearings. Also the ceramic bearings doesnt make that much sense if the surface on which they roll are not also ceramic... There is a hambini video about this topic I think ^^
6:56 i took me an hour to do that then i realized what i did wrong... apply force on the derailleur spring and hanger portion to bring the cage out on your bike shift it to the largest cog... will make it a whole lot easier!
I just ran across this vid and had the exact same thought...."dimension-ally identical". Eerr....just pull the seals off and presto. Oh...and put some ceramic bearing grease in there.
Is it possible to use the rubber seal from another bearing and put it over the ceramic bearing? As they are the same size (outer diameter), I was wondering if the inner dimensions are the same enabling the ceramic bearing to be closed with a rubber seal?
Anything with bearings will be better than bushings for derailleurs. The same goes for rear shocks on mountain bikes. I switched to needle bearings years ago for my rear shock. But I agree that the bearings need seals.
Thank you so much, your videos are always informative and clean cut to the point. Been researching for months if the R7000 RD is compatible with the R4700 RD of shimano. Thank you.
Hey Luke @Trace Velo, I've tried everything remove the endcap of the original pulley wheels in order to put the sealed bearings, but they wont come out. They seem to be pressfited really tight in there. Do you have any recomandation on how to get them out?
Yeah i struggled with my set actually. What worked for me, was getting a sharp kitchen knife, and carefully working it around the end cap to slowly get a gap between the pulley wheel and the cap. Once you have a little gap to work with, its relatively easy to get one side off. Obviously be EXTREMELY careful, but a thin sharp knife is best.
The CARBON LUBE you have shown us...will this sort of thing be useful for CARBON SEAT POSTS fitted into Ally Frame...?? Mine kept slowly dropping over the course of a ride..back home and raising it again was dissapointing to see carbon seat post all scratched and dulled permanently....as soon as i went back to metal seat post same dimensions...no slip at all...
Hello , thanx for the videos , they are quite interesting and funny . I saw you using Giyo gloves , could make a review for those someday? Thank you!!!
I was eyeing this on aliexpress but I remembered the unsealed bearing....so I opted for a delrin hsc ceramic jockey wheels instead which is direct replacement of stock ultegra jockey wheels.
Have considered putting high quality complete ceramic bearings in the jockey wheels? Also, could a rubber gasket ring be put between that cover plate and the bearing to seal it against wet getting into the bearing?
Rubber gasket would cause enough drag to defeat the purpose of using ceramic bearings. He could buy normal sealed ceramic bearings, as you say, and install those. But a bicycle in wet muddy environment is really not the place to use ceramic bearings. A good name brand set of 689-2RS ceramics is in the $50+ range anyway.
@@jaro6985 I was not suggesting adding the gasket over the ball bearings but along the perimeter of the cap that covers them. Regardless, higher quality and sealed bearings would be better.
@@AirwolfCrazy perimeter cap is what I assumed and would result in a similar level of loss. You can get low friction rubber seal (2RU), but, the seal is not as good, its all compromise.
@@febryanvaldo that’s true when compared to mega low-end callipers like Sora or the cheaper Tektro brakes, but compared to Dura-ace and SRAM red callipers, Fouriers and KCNC CB9 come out lighter and around half the price
Yeah I have been on the lookout for some decent lightweight rim bake calipers. But like some of the comments have said, Fouriers and KCNC stuff is still pretty premium for what you get in terms of weight savings over regular calipers. I'll def keep an eye out tho!
Those bearing rubber seal caps are usually removable, by using a small flathead or a thin metal tip to pry it out. Will you be able to remove the rubber seals and fit them onto the ceramic bearings? or are the ceramic bearings that come on those jockey wheels simply incompatible with those rubber seal caps?
I was trying to find just the inner and outer plates for my derailleur because mine have started to rust. Couldn't find them anywhere ended up buying something similar to yours. Question: Did you have to put on a longer chain? 🤔
Yeah you basically do. I think in this video I mentioned that you don't have to, and that is sometimes true, but in the vast majority of cases, you will need a few extra links in the chain.

Just wondering, as the ceramic and aluminium bearings are the same size, could you harvest the seals from the aluminium and put them on the ceramic?
Looking forward to an update on the Elite wheels
Yeah its probably going to be a while until I do a dedicated update on the EliteWheels, but so far so good. Admittedly ive only done a few hundrerd miles on them, but still perfoming great!
Just came across this video. Would you know what the size reference code is for the bearings? Looking to replace as well. Thanks!
689RS.
An informative and entertaining video again. When you were demonstrating the gear shifting on the trainer, it looks as though you need to do a few extra links in your chain. Did you put any more links in to compensate for the larger jockey wheels?
I mentioned it before, but is it not possible to pop the seals out of the other bearings and put them in the ceramic bearings?
Yeah great question. So I actually tried this, and it totally doesn't work. I think the diameter of the ceramic bearings are slightly larger that the regular steel ones, so adding the seals completely jams up the ceramic bearings unfortunately.
@@TraceVelo Doh! You need a friend with a 3d printer..... Maybe they could print some baring covers.
If someone is curious why they dont add bearing covers -> the covers are the main reason for friction/power loss. I would say you lose more with bad fitted covers instead of that what you get from the ceramic bearings. Also the ceramic bearings doesnt make that much sense if the surface on which they roll are not also ceramic...
There is a hambini video about this topic I think ^^
Trace Velo can you replace those lixada jockey wheels bearing with 689 2rs?
6:56 i took me an hour to do that then i realized what i did wrong... apply force on the derailleur spring and hanger portion to bring the cage out on your bike shift it to the largest cog... will make it a whole lot easier!
Love your presentation style. Quite wonderful!
Could you just put seals on the ceramic bearings?
I just ran across this vid and had the exact same thought...."dimension-ally identical". Eerr....just pull the seals off and presto. Oh...and put some ceramic bearing grease in there.
@@thefrontrangermtb5308 just what i thought
You should review Chinese speed play pedals with the TI axils suspensiosly cheap
Is it possible to use the rubber seal from another bearing and put it over the ceramic bearing? As they are the same size (outer diameter), I was wondering if the inner dimensions are the same enabling the ceramic bearing to be closed with a rubber seal?
So does the inside of the chain rubbing on the jockey wheels cause friction? Wouldn't a larger jockey wheel cause more friction?
Anything with bearings will be better than bushings for derailleurs. The same goes for rear shocks on mountain bikes. I switched to needle bearings years ago for my rear shock. But I agree that the bearings need seals.
Thank you so much, your videos are always informative and clean cut to the point. Been researching for months if the R7000 RD is compatible with the R4700 RD of shimano. Thank you.
alway wondered if it{s possible to put that in a SAINT derailleur or not. }
I didn't see links for this product or the pulley wheels with the sealed ceramic bearings as I would like to do exactly what you did.
Old video but cant you put a sealing on the bearings?
Yeah so I tried this, and it totally doesn't work. I think the bearings are larger in diameter than standard steel ones
Hey Luke @Trace Velo, I've tried everything remove the endcap of the original pulley wheels in order to put the sealed bearings, but they wont come out. They seem to be pressfited really tight in there. Do you have any recomandation on how to get them out?
Yeah i struggled with my set actually. What worked for me, was getting a sharp kitchen knife, and carefully working it around the end cap to slowly get a gap between the pulley wheel and the cap. Once you have a little gap to work with, its relatively easy to get one side off. Obviously be EXTREMELY careful, but a thin sharp knife is best.
The CARBON LUBE you have shown us...will this sort of thing be useful for CARBON SEAT POSTS fitted into Ally Frame...??
Mine kept slowly dropping over the course of a ride..back home and raising it again was dissapointing to see carbon seat post all scratched and dulled permanently....as soon as i went back to metal seat post same dimensions...no slip at all...
Did you have to add some chain segments. Is the chain length the same?
Wanted to know too 😊
Hello , thanx for the videos , they are quite interesting and funny . I saw you using Giyo gloves , could make a review for those someday? Thank you!!!
I love your videos and they way you produce them. Some much awesomesauce.
I was eyeing this on aliexpress but I remembered the unsealed bearing....so I opted for a delrin hsc ceramic jockey wheels instead which is direct replacement of stock ultegra jockey wheels.
Have considered putting high quality complete ceramic bearings in the jockey wheels?
Also, could a rubber gasket ring be put between that cover plate and the bearing to seal it against wet getting into the bearing?
Rubber gasket would cause enough drag to defeat the purpose of using ceramic bearings. He could buy normal sealed ceramic bearings, as you say, and install those. But a bicycle in wet muddy environment is really not the place to use ceramic bearings. A good name brand set of 689-2RS ceramics is in the $50+ range anyway.
@@jaro6985 I was not suggesting adding the gasket over the ball bearings but along the perimeter of the cap that covers them. Regardless, higher quality and sealed bearings would be better.
@@AirwolfCrazy perimeter cap is what I assumed and would result in a similar level of loss. You can get low friction rubber seal (2RU), but, the seal is not as good, its all compromise.
Ok, just brainstorming.
Does someone know what's the model number of those sealed bearings?
So the bearing code is 689 2RS
@@TraceVelo thanks! Love your content. Bought a fair share of chinese carbon because of this channel 😂.
How about a review on a set of cheap(-ish) lightweight brake callipers? Something from KCNC or Fouriers? Great video as well mate
KCNC and FOURIERS is no way near cheap. They're expensive.
@@febryanvaldo that’s true when compared to mega low-end callipers like Sora or the cheaper Tektro brakes, but compared to Dura-ace and SRAM red callipers, Fouriers and KCNC CB9 come out lighter and around half the price
@@ollieoxley7382 oh yes, if that's what you mean
Yeah I have been on the lookout for some decent lightweight rim bake calipers. But like some of the comments have said, Fouriers and KCNC stuff is still pretty premium for what you get in terms of weight savings over regular calipers. I'll def keep an eye out tho!
@@TraceVelo fair enough mate, been looking to get a pair of the lighter callipers hence the question. Keep up the good work mate, cracking content 👌
great production as usual luke ...thanks
Those bearing rubber seal caps are usually removable, by using a small flathead or a thin metal tip to pry it out. Will you be able to remove the rubber seals and fit them onto the ceramic bearings? or are the ceramic bearings that come on those jockey wheels simply incompatible with those rubber seal caps?
Nice video... And a suggestion... could you do your cheap version of a gravel bike from China...
Cesar, I would freaking love to do this, just need to find room for another bike :P
I was trying to find just the inner and outer plates for my derailleur because mine have started to rust. Couldn't find them anywhere ended up buying something similar to yours. Question: Did you have to put on a longer chain? 🤔
Yeah you basically do. I think in this video I mentioned that you don't have to, and that is sometimes true, but in the vast majority of cases, you will need a few extra links in the chain.
Absolutely mad question here but why not pop the seals into the ceramic ones?
you might be able to remove the rubber seals and place them in the ceramic bearings
How have you found the correct chain tension? More teeth through the pulley wheels would mean longer chain, right?
