Do ceramic jockey wheels make a difference?

According to research, a well-made ceramic bearing will roll faster, saving you energy and allowing faster cruising speeds compared to an equivalent steel bearing. This is because the properties of ceramic allow the creation of rounder, smoother bearings.

Do oversize jockey wheels make a difference?

But oversize pulley wheels actually offer enough of an advantage in wattage savings that it may be worth sacrificing style. So by opening up those angles and making them less sharp, the chain can articulate less than it would when it passes around smaller pulley wheels. Voila! Less friction.

Are jockey wheels universal?

Many jockey wheels are universal, a few are brand or possibly even mech specific. Take care if you have anything particularly exotic, a standard pair may not do the job.

Should jockey wheels have play?

Is this play important? Supposedly, the lateral play in the upper jockey wheel assures clean shifts even if the derailleur adjustment is a bit off. So with perfect derailleur adjustment, a jockey wheel without lateral play could well deliver crisper shifts.

What are the different sizes of jockey wheels?

I’m wondering about the variations in jockey wheels / derailleur pulleys and what differences they make; There’s a lot of conflicting and confusing information out there, so I’m after some general opinion on them. Common sizes appear to be 10T, 11T, 13T.

How is a jockey wheel attached to a boat trailer?

Why do Jockey wheels sit closer to the cassette?

Big upper jockey wheels sit closer to the cassette when your on the larger rings and reduce the total number of teeth that can be on the cassette (whereas a same caged sized derailleur with smaller jockey wheels may be able to deal with bigger rings). Praise the lord for this forum.

Which is tension, which is guide on a jockey wheel?

If there is adequate clearance between the top pulley and all the gears for the chain to run and shift smoothly then it’s fine. If there’s trouble, try switching the pulleys. My ‘guess’ is that if one pulley is smaller then it’s the top guide pulley.
