Westrick Rim
A colloquial name for Raleigh pattern rims. "Westrick" is a made-up word combining "Westwood" with "Endrick." Westwood rims were only for use with rod brakes; Endrick rims were only for use with caliper brakes, but Raleigh Pattern, a.k.a. "Westrick" rims can be used with either type.
They combine the raised (or dropped, depending how you look at it) center that keeps rod brake shoes free from the risk of hitting the spokes, with the flat sides required for rim brakes.
One excellent feature of Westrick rims is their parallel sidewalls, which allow a caliper brake to work more evenly if a rim is out of true. However, the hollow, steel sidewalls are easily deformed by curb and pothole impacts, and the chromed steel braking surfaces are very slippery when wet.
