Delivered in about 3days so ok. Price possibly not the cheapest on-line but hopefully good quality & reputable source. I fitted it to my off-road mountain bike front qwheel hub & the dimnensions were spot on. The old bearing failed because water got into it & it rusted but the seals on theses bearings are not 100% water-proof. They are only splash proof so anyone who does a lot of off-roading through deep water like I do should strip & re-pack the bearings periodically with a high quality water-proof grease. The seals are easily removable with care using a very small flat blade or electricians screw driver. My wheel is now running smooth & quiet again - Happy Days! Mk
