Great price
no problem
I use these bearings in my Shimano Curado 200 reel. Shimanoo used to give you these bearings free to repair your reel. They do not any longer. The bearings at VXB are the exact replacement part for the reel. I'm sure they have the correct bearings for many of my other reels. They are very friendly and are happy to help. I purchased my bearings in person.
Staff was very helpful in helping us find the correct bearing. Having it in stock was a plus! We have used hundreds of this bearing and have never found a flawed item!! QC is very good...
