Brand new ceramic bearings from Ceramicspeed. It is the top-of-the-line Coated Ceramic version.

The bearing is the 626 2RS version. It is used in several different bicycles, usually as part of the rear suspension system on a full-suspension mountain bike, or as the bearing in the pulley wheels. They for instance fit in Ceramicspeed's own alloy pulley wheels.

All CeramicSpeed Bearings are hand-built in Denmark. The super-smooth CeramicSpeed grade 3 Silicon Nitride balls are matched (within microns) with hardened steel raceways that feature an ultra-smooth polished groove.

The balls are held in place by a reinforced polyamide cage. Non-contact seals complete the bearings, keeping dirt and moisture out. CeramicSpeed Bearings can be used for any cycling discipline: Road, TT, Tri, Track, Cross, and MTB. The benefits are super low friction, better power transfer, and increased bearing life.

During the building process, we check each bearing four times by hand to ensure that all parts are matched perfectly. CeramicSpeed Balls are 400% smoother, 128% harder, and 58% lighter than standard steel bearings normally used in the bicycle industry. When comparing the CeramicSpeed Balls with other ceramic balls in the industry, you will find that the CeramicSpeed Balls are 15% harder, take 99% higher loads, and are 100% smoother.

CeramicSpeed offers a lifetime warranty on originally purchased Coated products and oversized pulley wheels - read more here.

Note:
These bearings are sold individually. The bearings are not greased and will therefore need to be greased with Ceramicspeed grease before being installed and used. The grease is not included but can be purchased separately. Ceramicspeed offers different types of grease for different types of use, so get the right one for your purpose.
