Before the dizzying array of bottom bracket standards that all just look like a gaping hole in your frame, bottom bracket cups used to thread in to precisely-manufactured frames, and lasted darn near forever, rarely creaking. The Chris King ThreadFit 24mm bottom bracket is the perfect match for one of those frames of yesteryear (or current day, if you look for the manufacturers hesitant to jump on the latest fads). It’s designed to accept 24mm spindles, and tapered 22/24mm spindles, like you’ll find on most modern cranksets from Shimano, SRAM, FSA, etc. Beyond the satisfaction that your bottom bracket assembly will be the most colorful, you’ll also spin smoothly on King’s legendary bearings.
