Shimano XTR Shadow Plus – Lower Jockey Wheel Rapid Wear
So, my lower jockey is getting reet pointy. Thinking I could do with either a new lower or a pair but the choices out there are bewildering.
I understand the top jockey needs “float” and this is a patented Shimano thingumabob?
Any ideas or recommendations on a replacement pair of jockey wheels that work – at a decent price?

This is one thing i’ve never understood…. Can someone explain to me (or tell me i’m right? 🙂 )Posted 4 years ago
The jockey wheels on my SRAM wore out a long time ago… only tiny and very pointy teeth left. It doesn’t seem to affect anything at all- all the jockey wheels do is route the chain around the cage- they don’t take any of the pedalling force, and there’s nowhere for the chain to fall off, so i’ve never really understood why they need teeth. Woulnt a plastic roller work just as well?
I’m sure I’ve seen a jockey wheel that was actually a safrifical block of dry chain lube or maybe waxy polymer so lubed the chain as it rolled over. If someone made them really cheap they could sell them by the bucket load.
just googled: http://www.carbonforbikes.com/ they are carbon lubricant. Like you use for locks, high temp applications etc.Posted 4 years ago
The solid lubricant is shaped like the jockey pulleys of the derailleur. All you need to do is replace the bottom jockey pulley in the rear derailleur.
The abrasion of the lubricant that occurs through contact with the chain while pedaling results in lubrication.
I really like the idea of that – has anyone tried one of these to see how they work in practice?Posted 4 years ago
Also I couldn’t see info on how long they last for, anyone know?
Their website claims 1000-1500 kms.
Does it not just lube the part of the link it contacts though (rather than inside the rollers which is where you really want it)?
Again, their website claims it has ‘creeping’ abilities so will work its way into the rollers. But I think I’d be inclined to start with an application of teflon dry lube inside the rollers, and just rely on the graphite jockey wheel to keep things moving from thereon…
Be nice if someone had experience using them could verify their claims…Posted 4 years ago
no idea what the lubrication performance is like under load etc though.
Says ideal for saline conditions and dry film repels water.
Rocol do one for industrial ovens too (conveyor chains inside oven)Posted 4 years ago
