These KCNC derailleur pulleys are a high-quality upgrade for Shimano and SRAM systems. Users report significantly improved performance, with faster, smoother, and more precise shifting.

Excellent pulley

2026/01/06

roldana kcnc

I highly recommend it; it's high quality and works perfectly. You'll definitely notice the difference when you replace the original Shimano part.

Runs very smooth

2025/11/08

johannes-ernst

I use these on Shimano XT 12 speed, the KCNC run much smoother then the original.

Turns well

2025/11/07

Christophe

Mounted on a GRX 11-speed derailleur, it does the job very well with a bit more road buzz compared to GRX plastic pulleys. Easy to install and maintain

Good product

2025/11/06

Jon

I installed them on my mountain bike's XT 12-speed SGS derailleur and they work perfectly. They come pre-greased; you just need to insert the screw and you're good to go. They're noticeably smoother than the originals.

I changed them for an Ultegra di2 12v change and I recommend them 100%. Ceramics are not necessary, they are great.

Amazing color

2024/06/05

LuisA

The color is wonderful, there are almost no brands that handle such a vivid color and the bearing is of quality and spins very well. I recommend it. KCNC did an excellent job in machining and anodizing.

Everything ok, fast shipping.

Look nice and work fine

2024/04/08

Roberto

I have just installed them but haven't yet ridden my bike. They look very nice and roll pretty well (I would say as well as the Shimano Ultegra pulleys). So far so good.

Very nice pulleys

They have been working flawlessly for ten months now, in extremely wet muddy west coast Canada off-road conditions. Thumbs up!

KCNC Derailleur Pulley Black 12t Ref: (14096081) hi, I would like to know if this pulley is compatible with shimano 105 DJ2 7150 ? Thank you !

Good quality/price

2023/07/27

Carlos

for now they are going well and the price quality is good

They improve the change a lot

2023/04/26

Isaac

Replacing my shimano rollers with bushings for these kcnc bearings has greatly improved the change. The chainring has stopped sucking on my chain, the lower roller has stopped pinching the chain and jumping, I have gained watts because they have less friction and the gearing is finer, it changes faster and is more precise. I have a Shimano 9v relief and it seems that I have a shimano XT because of how well it shifts now with these pulleys. 100% recommended. They greatly improve shift quality.

Kladky 13 zubů

2022/10/03

KCNC 13 zubů

Kladky KCNC jsem použil pro mou přehazovačku shimano XTR 9100, kde je potřeba použít velikost 13 zubů. Při montáži nelze použít originální šrouby kladek, ale musí se použít jiné s rovným závitem. Shimano má uprostřed vybraní, které brání použití jiných, než originálních kladek... Pozor při objednávání - pokud chcete obě kladky musíte objednat 2 kusy. Jsou dodávány po jedné.

On all of my bikes

2022/08/03

Vince

I used KCNC pulleys on all my bikes. Makes shifting smoother and quieter. Great for Shimano or SRAM.

Shimano 105

2025/10/07

Miguel

Hello, I have a Shimano 105 11-speed mechanical derailleur. Would these be compatible?

Answer of Antonio Giuseppe

It also works with 105.

Answer of Antonin

Hello, yes, no problem, I did it on mine.

Are these with ceramic bearings

2025/04/23

Martin

Hi are these pulleys with ceramic bearings or steel?

Answer of Jean-François

Steel bearing.

2024/09/19

Esteban

I have an XTR derailleur and the lower pulley is worn. Is the new pulley compatible or does it need a bushing?

Answer of Albino

My derailleur is SRAM. The KCNC pulleys are compatible with Shimano and are excellent. Very high quality product.

Answer of Gianmarco

I used it on an Ultegra derailleur and didn´t need anything.

Roldana 13 t

2024/08/12

Cesar Zarzo

Hi, I have an 11v Ultegra R8000 derailleur. Could I put the 13-tooth one on the tension pulley? Or will it tighten the chain too much? Thanks.

Answer of Dan

The specs for R8000 11speed Ultegra specify 11 teeth pulleys. Check yours first, the best bet is to use pulleys with the same number of teeth, otherwise you might need to make some modifications to your derailleur cage in order to fit them.

Answer of Eduardo

Hello, in my case, I changed the two pulleys (tension and guide) for 12-tooth KCNC pulleys and they worked perfectly and the chain had good tension.

Pulleys

2024/05/19

Ismael

I have a 105 di 2 derailleur, with two pulleys with 11 teeth and a diameter of 446 mm, these pulleys are compatible and someone has tried putting a 12 or 13 in the lower gear of the derailleur, thank you

Answer of Boy

I use this on a grx derailleur, 11 on top and 13 on the bottom. Works perfectly and runs much smoother than the original Shimano wheels.

SRAM GX 11V Compatibility

2024/03/30

Santiago

Hello, I wanted to know if they are compatible with my SRAM GX 1x11 speed derailleur. Thank you

Answer of RODOLFO

It is not ceramic. I bought it for a Shimano Ultegra shift, and the truth is that it works very well.

Answer of Davide

Yes it´s good for 11 speeds

Compatible capagnolo

2024/03/09

Ander

Hello, I would like to know if it is compatible with a Campagnolo chorus mechanical 11v gearbox. Thank you

Answer of CARLOS

Normally Campagnolo uses pulleys with more teeth than Shimano, but count them in the derailleur and order the appropriate ones, because KCNC has several tooth possibilities. Otherwise, they are going very well. I always have metal pulleys on the derailleur. All the best

Answer of David

Take out the original pulley and if the number with the "T" is written on it (example 11t) in theory, I think it works

Answer of fausto

I think so, I mounted it on a Super record gearbox and it works fine.

Ultegra R8150 12 speed

2024/01/26

R A

Doest it work with R8150 12 speed?

Answer of Salvador

I have it mounted on a 12-speed 8100 on the MTB and it runs very well.

Compatibility with sram axs 12V

2024/01/21

Didier

Hello I have a SRAM AXS 12V derailleur I would like to know if these pulleys are compatible Thank you

Answer of Davide

Hi this pulley has 11 teeth and is good for 11 Sram speeds You should count how many teeth your gear pulley has

Josep M

Hello, good afternoon, I would like to know how many rollers are per package. Thank you

Answer of Daniel

Hello, one per package. All the best

GRX compatibility?

2023/07/07

Carlos

Are you compatible with cambio grx 2x10?

Answer of Pablo

If it supports that change

Shimano Ultegra 11v compatibility

2023/06/25

Santiago

Hello, I wanted to know if these pulleys would work for a Shimano Ultegra R8000 11v medium leg derailleur, now the ones I have are 11 teeth. Or if you could mount a 12 tooth sheave on top and a 13 tooth sheave on the bottom. Thanks and best regards

Answer of Daniel

hello. I made that same change but on a shimano 105 and it was perfect. In fact, I still have room to put larger diameter rollers, but the way I put them is fine for me. 2 more teeth on a pulley does not increase the diameter of the pulley very much.

Answer of pedro luis

Hi, if they fit you shouldn´t have any problems, although Shimano chains are somewhat special with the teeth. I have them on a Sram derailleur and they go very well.

sram gx 12V

2023/05/19

jeremy

Hello, I have a sram Gx 12 speed MTB it is compatible

Answer of Daniel

If it is compatible. Especially if it has the same number of teeth as the one you´re wearing on the derailleur.

Answer of Antonio Jesús

I used it with GX and it was perfect...

Answer of Pavel

Já používám na své XTR 9100 a funguje bez problémů. Na GX bude fungovat také, pokud použijete správný počet zubů na kladce. Šrouby můžete použít z vaší prehazovačky. Kladky vypadají perfektně a skvěle fungují i v blátivých podmínkách. Nemějte obavy je použít. Doporučuji.

Answer of pedro luis

Hello, yes, it is the 12-tooth one, it is totally compatible, I put it in to replace the one above. Below I put a 16 tooth, they are going very well after 6 months.

Answer of Pablo

It is not compatible because of the number of teeth

Type of bearings...

2022/12/28

Francisco

Hello. What type of bearings does this roller have? I would like sealed steel ball bearings. Thank you.

Answer of Ángel

I have them and they have sealed ball bearings. I have them on the road bike and they are very fine.

change

2022/10/02

francisco

Are these compatible with shimano ultegra electronic and normal? Thanks.

Answer of Pavel

Ano, jsou kompatibilní se všemi typy přehazovaček. Záleží jen na počtu zubů, jaký potřebujete. Možná ale budete potřebovat jiné šrouby, než používá Shimano. KCNC je má v nabídce v různých barvách.

Answer of Pablo

Yes and it works very well

Kcnc sheaves 12 teeth

2022/09/21

David Bosano

Good, the other day I made a query about the length of the teeth of the 12-tooth kcnc pulley. José Miguel answered, but not to my doubt. I know they go well with short teeth, but I want them with long teeth, like the 11-tooth ones that appear in the product photo. I ask the question again: Are the 12-tooth ones long-toothed? Thank you

Answer of Pavel

Délka zubů je u všech kladek stejná. Tak jako je stejný profil zubu. Pouze u menší kladky s 11 zuby se zdá výška větší, než u 12ti zubové. Je to tedy jen optický klam na obrázku. Kladky jsou kvalitní a budou pracovat přesně podle vašich potřeb.

Sheave teeth size 12 black

2022/09/15

David Bosano

Good. The photo shows a pulley with 11 long teeth. I would like to know if the 12 teeth are also long or if they are short. I have already had this problem in other places where finally the 12 are short and I am interested in long. Thank you!

Answer of José Miguel

They are teeth for a 12 chain and it goes well

Shimano xt 12v compatibility

2022/08/20

Simone

Hello, Is it compatible on Shimano XT 12v? M8100? THANK YOU

Answer of Antonio

Yes, I have it in sram but a colleague put it on an xt derailleur and it´s perfect

SRAM Red 10v

2022/06/28

Alejandro

Hi, is it for Sram Red 10v? Thx

Answer of Enric

In my case, I mounted it on a Shimano 10v, if the number of teeth matches the pulley to be replaced, you shouldn´t have a problem.

Answer of Antonio Jesús

The chains (which is what is in contact with the pulley) are compatible between brands... If you get a 14-tooth chain in the cage, you shouldn´t have a problem.

Technical question

2022/06/24

giorgio de angelis

2 pulleys, ???? how should they be mounted? which side do they go towards the gearbox ?? which below is which above? are there any positions to respect ??? thank you, or just one pulley

Answer of Enric

Each order consists of 1 single pulley, its assembly above or below as you ask is dependent on the number of teeth you have on the pulley to be replaced, if it matches it does not matter where you place it, it is a symmetrical piece so you can mount it on the side you want.

Would it work for a sram sx eagle? 12v

2022/06/20

Luko

Would it work for a 12v SRAM SX Eagle?

Answer of Enric

In my case I installed it on a Shimano 10v and it works great, I think you should count the teeth of the pulley to replace and it should match the new one.

Answer of Antonio Jesús

I use it with SLX, but the heads are compatible... It works for SRAM.

Pulley kcnc

2022/05/13

Roldana kcnc

Hi, good! This model of sheaves is valid for both the bottom and the top of the derailleur. I ask because it gives me the impression that for the bottom part you need a higher tooth. Once with a similar sheave, the chain came out of it. By putting a roller with a higher tooth it seemed that it stopped coming out Thank you and regards

Answer of Enric

Very good. In my case I have it mounted on the bottom and it works perfectly from the first day... I have it mounted on a 10v XT, it only asks for a few drops of good lubricant at each start, the truth is that for being aluminum its wear is not exaggerated. I sincerely recommend this product!

Compatibility

2022/01/11

Emilio

Hello, I would like to know if these pulleys are compatible with the sram force of 11v long leg, I have to change my two pulleys and I want to know which ones are compatible, I would have to change the chain as well or I can continue to keep the current one.

Answer of Manel

I don´t know with a short leg it´s sure going well.
