Crankset & Bottom Bracket Compatibility
The 18307 is a highly specialized bearing. Its primary application is for modern, oversized crankset and bottom bracket systems. It is the specified bearing size for many components from FSA (notably the MegaEvo and BB386EVO standards), Rotor (such as the 3D+ and 3D30 cranks), and Easton (EC90 SL cranks). Always confirm your specific model's requirements before purchase.
Frequently Asked Questions (FAQ)
Q: What is a 18307 bearing used for?
A: It's a specialized bearing used in high-performance crankset systems. Its unique 18x30x7mm size is required by certain modern bottom bracket standards like FSA's MegaEvo and is also compatible with cranksets from brands like Rotor and Easton.
Q: Is this the correct bearing for my FSA BB386EVO bottom bracket?
A: The BB386EVO standard is complex. The 18307 bearing is a key component within this ecosystem, specifically used to adapt certain crank spindles to the BB shell. It's essential to verify if your specific crank and bottom bracket combination requires the 18307 bearing before servicing.
Q: What is BB386EVO?
A: BB386EVO is a bottom bracket standard developed by FSA. It combines a wide 86.5mm shell (like a PressFit BB86) with a long 30mm diameter spindle (like BB30). This versatile design requires specific bearings and adapters, like the 18307, to accommodate different cranksets.
Q: Do I need special tools to replace bottom bracket bearings?
A: Yes. Servicing modern press-fit bottom brackets requires specific bearing press and removal tools designed for your exact BB standard. Using the wrong tools can damage your frame or components. We always recommend professional installation by an experienced mechanic.
