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 oversized pulley wheels worth it?
‘Larger pulley wheels decrease the amount of articulation required from the chain links,’ says Ard Kessels, founder of Kogel Bearings. Additionally a larger pulley wheel rotates slower than a smaller wheel, reducing bearing speed and therefore bearing friction.
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 I need a longer chain for oversized jockey wheels?
Oversized pulleys do not require a new chain – Since the added length in the chain is only about 2 teeth, typically you can run oversized pulleys without having to replace your chain. One nearly unavoidable downside of oversized derailleur cages remains the need for a longer chain.
Are CeramicSpeed jockey wheels worth it?
Yes, CeramicSpeed has indisputably invested more into research and competitive testing than any other company in the space. Yes, quality and tolerances are great. Yes, the OSPW features top-class ceramic bearings and a quality fibre-reinforced composite cage. But you can’t ignore that price.
Do you need a longer chain for OSPW?
A standard chain will be long enough to fit the new OSPW System. You will need to remove fewer, if any, links when installing a new standard chain.
Is it worth changing jockey wheels?
If the teeth on the jockey wheel are worn and rounded or sharp and jagged, it’s usually worth replacing to save the life of your chain, derailleur and cassette — which are more expensive parts. If the wheel doesn’t spin freely or grinds, your bearings could be worn down and your jockey wheels may need replacing.
What does an oversize pulley do?
It handles shifting too and it’s important to keep the derailleur on the bike when making a sharp right in a crit race, maybe a bit too close to a curb. This is where things get interesting: oversized pulleys mean a longer distance between the center of the pulley and where the chain runs.

Does ceramic speed work?
How long do jockey wheels last?
Unless you’re riding in sand or other ultra-harsh conditions, almost forever. They carry virtually no load and transmit zero torque, so tooth wear is minimal; the upper jockey wheel may be worth inspecting and replacing once in a while for the reasons u/jermleeds goes into.
