Hi i was wondering where people can get cheap bearings for handle knobs and such. On a reel like a curado 70, for example

4x7x2.5 is the size you need. You'll need 2 of them for that reel to make it a 4bb handle. If you have a hobby store near you that sells rc cars and helicopters you can get them there. If not then order them online.  

tackletrap is a good place for bearings.

ebay the blue seal 4x7x2.5 bearings.  never an issue and dirt cheap
