Up until about 10 years ago, virtually all bikes used a threaded bottom bracket. There were a few notable exceptions in the early 1990s from makers like Klein, Merlin and Gary Fisher — which used their own threadless press fit style BBs — but it wasn’t until Cannondale introduced its BB30 threadless system in the early 2000s that threadless bottom brackets started to go away.
Regardless of what is popular, many people still swear by threaded bottom brackets. Unlike press fit style BBs, which come in a dizzying number of sizes and standards, there are essentially just two type of threaded bottom brackets: BSA or Italian. And the latter is quite rare these days.
The advantages of threaded bottom brackets are well known. Since the bearing cups screw directly into the threaded BB shell of the bike, you get a secure connection that’s less prone to creaking noises. And if it does develop any problems or creaking — which can occur if you frequently ride in wet, grimy conditions — it’s easy to remove, clean, grease and reinstall.
Most of the threaded bottom brackets available today feature external bearings. This design increases the distance between the bearings, which boosts lateral stiffness compared to inboard threaded bearings. Shimano was an early advocate of this design, and today you can find external threaded bottom brackets from other brands, too, including SRAM, Race Face, Chris King, Easton and Hope. JensonUSA carries a wide variety of options for both road and mountain bikes.
Some older model bikes and drivetrains still use threaded bottom brackets with inboard bearings, as do many track bikes because of the narrower Q-Factor. And many recreational and lower priced bikes also feature the inboard design with a traditional square taper spindle.
Whatever type of threaded bottom bracket you need, JensonUSA has just the right solution. Feel free to call us and speak to one of our Gear Advisors today at 888-880-3811, who will be happy to help you find exactly what you are looking for.
