17x30x7mm Ceramic Ball Bearing | 6903 Bearing

Excelente

Haven’t installed them yet

The shipment was on time and the package was delivered without damage. These bearings were installed in my S&M BMX bike. So far (2 weeks of riding every day) so good. My bike is now SCARY to take on the skatepark. Go faster?!? CHECK! After another 10-14 days of riding everyday the bearing in my front wheel gave up. My review will stay at 4 stars because, well ceramic bearings are known to not hold up to constant impact forces applied by 2-3ft drops of 165lbs. Still a very nice bearing house.
