These are stock bearings for the 948. They are slightly narrower than origional, but will work and are what is commonly known as bi-metal bearings. They are ok for light road use. We highly recommend upgrading to the tri-metal bearings. For the extra $5 you get a much better bearing. We keep minimal stock of these, but can get any size in stock if this is the route you wish to go.
