CH61903-2RZ (6903 2RZ) Ceramic / Stainless Steel Hybrid Bike Bearing - Metric 17x30x7.
These high quality and affordable Ceramic Hybrid bearings have been specially manufactured for the bike industry. The lighter ceramic balls allow the bearing to spin faster, and uses less energy to maintain its speed.
Great service and products, highly recommended!

Simply great service and an apparently high quality component. Fitted as easily as any beating I've fitted before and runs far smoother than the original fit bearings in a SRAM roam wheel.
Firstly to service. Brilliant, ordered one day arrived the next, to Shetland! Second the bearings. I bought them as a replacement/upgrade for my Campagnolo Scirocco Wheel, the fit was perfect and so far the running is super smooth, whether they are any better than steel balls I don't know but they were 1/4 the price of CULT alternatives.
Very happy with these. Well worth the extra expense over standard items. My wheels now spin very very well.
