Westwood rims have rounded sides, so they are not suitable for use with caliper brakes. The inside circumference of the rim has a slightly concave profile to aid with seating of the brake pads and they often have a raised ridge down the centre to stop the blocks interfering with the spoke nipples.

Variations and sizes

Raleigh Bicycle Company developed a variation that combined the rod braking surfaces of Westwood rims with flat sides for caliper braking. It has been called "Raleigh Pattern" and "Westrick". They are notoriously strong, and there is also a Schwinn Bicycle Company copy of this design.

Westwood rims are most commonly seen in sizes 28 x 1 1/2" (635 mm), 26 X 1 3/8" and 20 X 2 1/2".
