Anyway do any of you have some pulley upgrade recommendations? I’m working on a budget so don’t suggest the 429 € Ceramic Speed Titanium pulleys.
I've found Tacx Stainless Jockey wheels are very durable, spin well and are reasonably priced.
Couldn't agree more. Too bad they're in this silly purple colour and they're definitely not the lightest out there.
As a matter of fact I found these to spin more freely than the ceramic hybrid version for some odd reason....
I've been running the same set of pulleys for a few years already. Lubricated with just a few drops of Triflow oil BTW.
My analysis here (with link to his page) showed the 15-tooth should save around 0.2% of total power. Small, but this forum is all about small improvements.
Overall, though, I think it's obvious from even a casual spin test that SRAM pulleys are way better than Dura-Ace... even Rival is better than Dura-Ace. Going beyond SRAM is marginal gains, according to that same blog post link (see Mark Kelly numbers).
I think they retain much of the shift quality of nicer pulleys, and perform plenty well through mud, dirt, rain, etc.
I'm going to plug in HSC delrin hybrid ceramic pulleys though, $35 for a pair at fairwheebikes. I'm using these on my chorus 11 rear derailleur, and it performs a lot better than stock. They spin very well, and the thinner profile of the the pulleys seem to shift a little better than stock chorus pulleys. Only gripe i have with them is that they're noticably louder than stock pulleys.

I don't think he is. I've tried contacting him for over a month now, no replies.

I wouldn't necessarily say BETTER, unless free spinning that is your sole goal with the pulleys. DA upper pulleys float side to side as part of its bearing assembly, without allowing twist. They're very nice, quiet, keep shifting spot-on. Ultegra uses a ceramic bushing material and large rubber wiper seals. you want lower drag for cheap? keep the pulley and remove the seals. the lower bearing is not a significant source for drag.
Sram pulleys may spin better when fresh, but at least around here, they foul much easier than shimanos.
