CeramicSpeed Oversized 3D Titanium Ceramic Coated Pulley Wheel System - Shimano 9100 and 9150

CeramicSpeed Oversized 3D Titanium Ceramic Coated Pulley Wheel System - Shimano 9100 and 9150 Info

Redefining performance upwards by reducing mechanical friction to zero is the guiding mission of CeramicSpeed. These Oversized 3D Printed Hollow Titanium OSPW for Shimano and SRAM do just that. Everything employed in this kit is as light and friction-free and cutting edge as is possible.

The heart of the kit are the 17-tooth pulleys. They are like nothing you’ve ever seen before. They are only possible by the manufacturing method. 3D printing. And as they’re made of titanium, they are both lighter, by 10%, and more durable, beyond CeramicSpeed’s testing protocol, than the machined aluminum CeramicSpeed utilizes in their other oversized pulleys. They figure these should last twice as long as their machined-aluminum cousins.

The bearings are CeramicSpeed’s coated race ceramic bearings. CeramicSpeed utilizes Grade 3 Silicon Nitride balls that possess the best possible surface finish and roundness. In testing, the balls are 400% smoother, 128% harder, and 58% lighter than standard steel balls found in most bike components. They’re more than 100% smoother and 15% harder than standard ceramic balls. Coated races are even smoother and longer lasting than their standard race counterparts, as it’s a metallic layer on top of the races, three microns thick and 75% harder than hardened steel races. The smoother track means less friction, less need for lubrication, far greater durabilityStandard CeramicSpeed 17-tooth pulleys save 2.37w compared to standard Dura-Ace. These save even more than that

The kit comes with two seventeen-tooth pulleys and are held in place with CeramicSpeed’s carbon-reinforced plastic arms, and the pulleys are secured with titanium bolts. The kit weighs 70g.  It comes with a bottle of their Pulley Wheel oil for proper lubrication.

This kit is compatible with Shimano 9100 Series, Mechanical and Electronic.

In terms of cassette size compatibility, this kit should work with cassettes ranging up to 28 teeth for Shimano, 32 for SRAM. Some derailleur hangers may make it impossible to get to these maximum sizes.

As you can imagine, installing this system is a bit more involved than replacing pulleys. Rest-assured, it is more straightforward than you fear. You’ll need a set of Allen keys. You can perform the installation on the bike or off, though on makes the installation a bit easier. You’ll probably also need a few more links in your chain, so starting with a new chain might be the easiest way to begin.

Devilishly, light, smooth, and rare, CeramicSpeed’s 3D Printed Hollow Titanium Oversized Pulley Wheels add performance and style to your bike.
