The Bottom bracket is a key component to every chainset. Smoothness movement is critical, yet must be balanced by enough sealing technology to sustain a reasonable lifetime of use. FSA MegaExo bottom brackets are the result of years of development, and feature exclusive innovations to guarantee the best balance of efficiency and durability. FSA use the state-of-the-art materials like Silicon Nitride formed ceramic ball bearins, or highly polished chrome steel ball bearings, depending of the level of the bottom bracket.

If you want to make sure you're making the most of every crank rotation, this is the bottom bracket to pair with your FSA ISIS type road bike chainset. With its forged titanium spindle and large upgraded bearings, it gives you super-smooth rotation and outstanding power transfer. Tech Info: Please note - The first two numbers in our options (eg. "68" 70 or "73") relate to how wide your bike's bottom bracket shell is in millimetres. The other three numbers (eg. 118) relate to how long your current bottom brackets spindle (axle) is in millimetres. The 68 and 73mm sizes are the "English thread" type, the 70mm size is the "Italian thread" type - please measure your bike's bottom bracket shell width to confirm which size you need.
