CeramicSpeed SRAM 11 Speed Pulley Wheels

CeramicSpeed Pulley Wheels that accommodate all SRAM 11s mechanical and electrical groupsets.

The pulley wheels are available in anodised aluminium or titanium and the latter can be fitted with either standard or coated CeramicSpeed Bearings.

Designed to fit all SRAM 11s mechanical and electrical derailleurs, these CeramicSpeed SRAM 11 Speed Pulley Wheels put less friction between the power transferred from your legs and the rear wheel.

Each pulley wheel is fitted with CeramicSpeed high quality bearings that offer for a more efficient drivetrain.

Features

Coated bearings -CeramicSpeed's coating has several performance enhancing properties that makes it unique.Thanks to their continuous R&D program, CeramicSpeed have developed a special coating in cooperation with a European coating specialist. Applied to the steel races of the bearing, through an advanced process that ensures an even, smooth and homogeneous surface, the coating formula improves even further the high quality of the CeramicSpeed bearings.

Low friction-Once coated, the bearing races deliver a hardness level matched only by the CeramicSpeed balls, providing an extremely low friction coefficient between the two materials. The result is thus even less friction in our coated bearings than in their standard bearings.

Coating Graf Friction-The coating is a metallic layer, which is 75% harder than the hardened steel races. The coating is applied in a very thin and even layer of 3 microns (0,003 mm) on the entire surface of the bearing race. Both the inside and the outside are treated to achieve optimal results. As CeramicSpeed use a metallic coating on top of the hardened steel, it can be difficult to see that a bearing is actually coated. However, if you take a closer look at a coated bearing, you will notice that the surface has a different shine than a standard CeramicSpeed bearing.

Lifetime -The coating has several properties that improve the lifetime of CeramicSpeed's bearings. The increased hardness of the races combined with the super smooth and round CeramicSpeed balls, means virtually no wear on the bearing.

The coating layer is applied completely closed and homogenous. The formula used for the coating is extremely resistant to corrosion. This means that even if the bearing is contaminated with degreaser, water or mud, the risk of bearing failure due to corrosion is negligible.

How to achieve the optimal performance -The coated bearings are more resistant to lack of lubrication when it comes to wear and damage on the bearing nonetheless, this does not mean that the need for maintenance is completely eliminated. Just as CeramicSpeed do with their standard bearings, they recommend to always lubricate them with our special grease to achieve optimal performance in terms of low friction and long lifetime. For all training and racing applications they recommend the use of CeramicSpeed Blue all-round grease. If you want to achieve the lowest possible friction, CeramicSpeed recommend you to use their TT grease. Please be aware that compared to the standard Blue all-round grease, the TT grease has a shortened lifetime and therefore, it requires more frequent application.

Handmade in Denmark-Like all other CeramicSpeed bearings, their coated products are handmade in Denmark. This means all bearings are built by hand and inspected manually at each step in the production process. Building a coated bearing adds a number of extra steps to the process. The CeramicSpeed balls and steel races are matched within microns after which, each set of races is coated. The races are kept together in pairs through the entire process and after coating, each set needs to pass the quality control before they go into production.

CeramicSpeed coated bearings are available for pulley wheels, bottom brackets, wheel bearings and the Oversized Pulley Wheel System.
