American BB, 19mm


The Hutch American bottom bracket includes high-quality ISK "brown bearing seal" bearings...a throwback to the quality brown-seal bearings that Hutch used in the 1980's. This set includes the vintage-style spacer washer set, and also the more modern cone-style spacer washers. This Hutch American BB fits all vintage BMX frames from any brand that have American bottom bracket sizing. The 19mm bearing fits all 19mm (3/4") crank spindles.
