BK CX Pulley Black - Max-type, Sealed Bearing, Seat Tube Cable Roller for Bottom-Pull Front Derailleurs
Not a particularly in-demand product in these days of 1X drivetrains, but this is a handy upgrade for many older Cyclocross bikes that have top tube cable routing and bottom-pull 2X or 3X front derailleurs.
This roller is precision machined from Black Delrin® and features an Enduro MAX-type bearing for long lasting smooth performance. Max-type bearings are designed without retainers to maximize the number of balls to spread the force over a greater surface area, pressure water and minimizing wear. MAX-type bearings also feature a deep-groove design that maximizes ball size, and LLU seals to give maximum protection against the elements, while keeping the 90% fill of Almagard extra high pressure grease inside.
