Jockey / Pulley wheels for Ultegra/105

[ViperFFM]

Sirs,

I am looking for ANY jockey / pulley wheel upgrade.

Not in terms of "friction performance" BS but just beacuse the stock pulleys magically collect all the dust and grit from the road. I have seen standard sized pulleys from Hope on a friends bike that hold up much better in this regard. Unfortunately tho I consider them to be a bit overpriced for what they are.

Any suggestions?

Dura Ace (which is alread similar to Ultegra). I believe 105 set does not have proper bearings.

[ViperFFM]

anyone?

Tacx jockey wheels work well and are cheap, but if you want a clean drive train you should think about waxing your chain instead of oiling it.

[Maddie]

Correct. The reason why other's jockey wheels stay are cleaner is not because they are different parts It's because of the chain lubricants. Wax your chain and your chain, cassette and pulleys will stay clean. There's a huge DIY chain wax guide thread, maybe worth a read.

Jumping in here too.
Have R7000GS in my TCR.
This site is suggesting a 12 and 14 tooth jockey wheel combo will fit.

Any cheaper options at that size, or is kogel the go?

I'm not convinced that oversize jockey wheels provide any meaningful reduction in friction over standard Dura-Ace jockey wheels with bearings. As others have mentioned, the cleanliness of the drivetrain and jockey wheels is mostly to do with the chain lube used and the way it was applied. As a general rule, wet lubes pick up gunk faster than dry lubes. Wax, perticularly chain off waxing, tends to be the cleanest. Just note to go to a wax based lube, you have to have your drivetrain CLEAN and your chain in perticular has to have all the oil removed or the wax won't stick. Once you get over that time consuming process, wax isn't any more trouble than any other lube.

For me its not about the ceanliness of my chain, but of my whole derailleur. When using 105/Ultegra in a gravel / wood setting, the jockey wheels, by design, collect loads of dirt and debris due to their notch design at inner part.

Switch to BBB Aluboys; cheapest alternative I could find that was recommended by Rhino. Went for one ride in muddy conditions so far and the difference is night and day.

Yeah fair point.
If I could get the slightly bigger wheels for a similar price then why not?
Not looking like it, so next parts order may have some BBB or Dura ace jockey wheels.

I'm about to purchase a set of Dura Ace jockey wheels to be used on a 105 RD, however have noticed that there are two varients available, the R9100 and the Di2.

The jockey wheels have slightly different teeth design and was wondering if one would perform better than the other? Even though one of them is labelled as Di2, it does say they are compatible with normal mechanical RDs.

The different options are:

R9100: https://www.bike-components.de/en/Shima ... ir-p52286/

Di2: https://www.bike-components.de/en/Shima ... ir-p38016/

I use Stone pulley wheels in my 105 derailleur, a non ceramic bearing, 12-14 tooth and narrow wide profile.

The first link is for R9100 Dura Ace, second link is for R9000 Dura Ace - it's mentioned in the product pages. No difference between mechanical or Di2 of the same generation.

Thanks Mike!

Do you use them with a 1x or 2x set-up, as looking at the description it advises narrow-wide should be used on a 1x set-up? I guess this is a copy and paste job from a chainring ad as I can't see how a narrow-wide jockey wheel can have any effect on the chainring set-up.

How did you compensate for the additional teeth on the jockey with your chain, did you need to add a link or two? Any chance you could attach a picture or two of your set-up?

I found I didn't have to add any links, just a B screw adjustment, I am running a 2x setup. Don't judge how dirty my bike is!
