There are a host of technical reasons for this, but the biggest and most basic one is that chains are designed to be carried by the bushings. It is a nice, big flat area designed for forces to be applied to it. Chains are not meant to be carried on the edges of their sideplates. It just doesn't work as well. Since the core of the idler is all metal, from the chain bushings through to the bearings, there is no sponginess to soak up power. The chain sideplates aren't used to transmit power down into the idler, so there is no rubbing contact like there is on plain bedded idlers. Noise is a complicated issue, but we expect you'll find these idlers are quieter than other idlers. The cog is specially shaped to smoothly and repeatably mesh with the chain, and unless the chain is being pulled sideways quite a bit, there will be very little rubbing. We always recommend allowing your power side idler to float side to side with the chain as it shifts. Another common source of noise in drivetrains is insufficient contact on the idler. If there is not enough deflection of the chain at the idler, the chain and the idler don't have a chance to mesh properly. This is true for all types of idlers. You'd think that a chain only lightly touching an idler would be quieter, but because of the complex geometries involved, there is a minimum amount of bend or wrap required to get maximum silence. The amount varies with the diameter of the idler, the larger the idler, the smaller the angle required.\u003cbr\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eWhat's the difference between these idlers and the Sport Series idlers?\u003cbr\u003e\u003cbr\u003eThe Elite Series idlers have titanium cogs, hybrid ceramic bearings, and completely CNC machined frames. The cog and frame are extensively hollowed out for lightness. They are designed to look as good as they work. The Sport Series idlers have 7075 Aluminum cogs, top quality steel bearings, and injection molded fiberglass reinforced Nylon frames. They are designed to be simple, high performance, and tough.

Shielded bearings have less rolling resistance because the seal, while super close, doesn't actually rub. True sealed bearings are rare, when people talk about \"sealed bearings\", they usually actually mean shielded. These are top quality shielded bearings and will last a long time. What kills bearings is solvent, dirt, and water intrusion. As long as you don't spray things on the bearing faces, you will be okay. Regular amounts of dust and dirt getting on the outsides of the bearings won't be a problem, as it's hard for it to get past the shields (the shields really do come *very* close to the bearings). When you clean them, what you want to do is gently wipe dirt off and away from bearings, rather than rub aggressively and push the dirt past the shields. There is no need to lube the bearings, the special grease that's in them is what they need.\u003c\/li\u003e\n\u003cli\u003eNo maintenance should be required other than occasional cleaning with a paper towel or soft cloth.

First there's its super-tough, exquisitely machined construction: the beautiful aerospace-grade nylon sideplates, the supremely durable industrial urethane chainbed and the immaculately designed inner cores. Then there's the bearing: either the unbeatable resilience and consistency of the precision hybrid ceramic bearings (8mm only) or top-quality ABEC-7 steel bearings (for other sizes). Never has a ride been so smooth and so reliable as with an Elite Return Idler.\u003c\/p\u003e\n\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003eWhat's so great about this idler?\u003cbr\u003e\u003cbr\u003eThis idler is a lightweight return side idler. It's in our Elite Series, which means the very best of everything. It has a very light machined-out aluminum frame. The chain runs on a tough industrial urethane bed. The sideplates are fiberglass reinforced Nylon, tapered to guide the chain in super quietly. Everything runs on a single top quality bearing. It's tough, light, and really sharp looking. It's the ultimate idler for any return application.\u003cbr\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eHow big is the idler?\u003cbr\u003e\u003cbr\u003eThe Return idler has an outside diameter of 2.75 inches (70mm) and is 0.60 inches (15.2mm) thick.\u003cbr\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCan this idler be repaired?\u003cbr\u003e\u003cbr\u003eYes, we can replace any element of the idler.

The urethane for the chainbed is specifically chosen for its durability and durometer. It is just the right level of cushioning, without being spongy. The sideplates are carefully tapered and rounded to minimize rubbing and noise.\u003cbr\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eWhat's the difference between these idlers and the Sport Series idlers?\u003cbr\u003e\u003cbr\u003eThe Elite Series idlers have run on hybrid ceramic bearings and feature completely CNC machined frames. The frames are extensively hollowed out for lightness. They are designed to look as good as they work. The Sport Series idlers are designed to be simple, high performance, and tough.

We don't recommend using Dumonde Pro series chainlubes with this idler.\u003c\/li\u003e\n\u003cli\u003eBearing Care: The bearing is shielded, not sealed. Shielded bearings have less rolling resistance because the seal, while super close, doesn't actually rub. True sealed bearings are rare, when people talk about \"sealed bearings\", they usually actually mean shielded. These are top quality shielded bearings and will last a long time. What kills bearings is solvent, dirt, and water intrusion. As long as you don't spray things on the bearing faces, you will be okay. Regular amounts of dust and dirt getting on the outsides of the bearings won't be a problem, as it's hard for it to get past the shields (the shields really do come *very* close to the bearings). When you clean them, what you want to do is gently wipe dirt off and away from bearings, rather than rub aggressively and push the dirt past the shields. There is no need to lube the bearing, the special grease that's in them is what they need.\u003c\/li\u003e\n\u003cli\u003eNo maintenance should be required other than occasional cleaning with a paper towel or soft cloth.
