If you want to make sure you're making the most of every crank rotation when you're on the road, this is the bottom bracket to pair with your FSA ISIS type road bike chainset. With its forged 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.
To ensure a smooth rotation that lasts ride after ride, FSA has included stainless steel ball bearings, which sit inside hardened steel races. This ensures this adapting bottom bracket operates efficiently and extends its lifespan. Tech Tip: If you are unsure whether to select the 68mm or the 73mm size, measure underneath your frames bottom bracket shell. Most road bike's BB30 shells are 68mm wide and most mountain bike's BB30 shells are 73mm wide.
