More road bike dreck.....Jockey wheels
So until some serious scheckels come my way....my upgrades are limited to my Italian Bikes....
Jockey wheels, aka those little roundy things on the rear derailleur. On one bike they have been making noise. Disassembly finds a rudimentary bearing. Lubed and tossed it back in. Noise is less but got me thinking..... A search on the net finds a lot of bling bling alloy wheels with pricey bearings. Claim to be more precise on shifts, less chain noise when the SIS is adjusted correctly and supposedly less friction meaning less exertion for the same speed.... Anybody use them....They worth it?

I used them once, alloy body with sealed bearing. Didn't work that great. It sure as hell wasn't better. At least in the case of shimano, they have it pretty well figured out, it seems to me, one wheel has a ceramic bearing the other has a steel bushing. One of them needs to float back and forth a small amount. I've never had any issues.....,.

Yeah, the Dura Ace ones have different wheels top and bottom. My Campy appear to be the same.

Top one definitely needs to float to assist in shifting. Way back in the day the sleeper mountain bike upgrade was Dura-Ace jockey wheels. Ceramic bushings and nice rubber seals to keep the dirt out. IIRC they were a touch thinner as well. Lots of folks pimping anodized this and billet that, but they never shifted as well as Shimano jockey wheels. That was of course a long time ago. I have no idea what the aftermarket looks like now.
Just went outside and looked at my 15+ year old mountain bike. XT mid-cage deraileur and Dura-Ace jockeys. |

So what is the hot set up for Italian trash? Chorus and/or Centaur?

As long as they are functioning properly then there is no need to change them IMO unless you are looking for every scientific advantage for less friction = more power measurable only by gauges in a lab. Just make sure they are clean and lubed, they should function for a long time. I have had the Bullseye seal bearing pulleys, ans I was still the last guy up the freaking hill. Not to bust your chops on Campy ( I grew up on racing on CAmpy and will always love them) but Shimano has been mention several times.

For jockey wheels I'd go Campagolo record. They're not expensive on EBay.
