Frame type

The frame type describes the bottom bracket shell standard. This standard is often listed in the manufacturer's bike specifications, but it can also be determined by measuring several dimensions of the bottom bracket shell, such as the width and inner diameter.
The values at a glance:
BSA — the cups are screwed directly into the frame with a 1.37″ × 24 thread. The bottom bracket shell is 68 mm (road) or 73 mm (MTB) wide.
ITA — the cups are screwed directly into the frame with a 36 × 24 thread. The bottom bracket shell is 70 mm wide.
T45 — the cups are screwed directly into the frame with an M45 × 1 thread. The bottom bracket shell is 82.5 mm wide.
T47 Outboard — T47 standard in which the bearings sit in cups outside the frame. The bottom bracket shell is 68 mm (road) or 73 mm (MTB) wide. The cups are screwed directly into the frame with an M47 × 1 thread.
T47A — asymmetric T47 variant with a bottom bracket shell width of 77 mm. The cups are screwed directly into the frame with an M47 × 1 thread.
T47 TREK / Inboard — T47 standard in which the bearings sit in cups inside the frame. The bottom bracket shell is 85.5 mm wide. The cups are screwed directly into the frame with an M47 × 1 thread.
BB30 — press-fit standard in which the bearings are fitted directly into the frame. The bottom bracket shell is 68 mm (road) or 73 mm (MTB) wide. Our Interlock bottom brackets also allow other crank types to be fitted.
BB30A — asymmetric variant of BB30 for road frames, used by Cannondale. On the non-drive side the bottom bracket shell is 5 mm wider than with BB30.
BB86/BB92 — widely used press-fit standard with a bottom bracket shell width of 86.5 mm (road) and 92 mm (MTB) respectively. Also called PF86.5 or PF92. The bearings sit in cups. This standard is used by Giant, Canyon, BMC, Cube and other brands.
BB89 — variant of BB86/BB92 with a bottom bracket shell width of 89.5 mm.
BB386 — press-fit standard with a bottom bracket shell width of 86.5 mm and an inner diameter of 46 mm. The large inner diameter of the shell makes the standard suitable for various crank axle diameters.
BB90 / BB95 — Trek-specific press-fit standard in which the bearings are fitted directly into the frame, without separate cups. The bottom bracket shell is 90.5 mm (road) or 95.5 mm (MTB) wide.
PF30 — press-fit standard with an inner diameter of 46 mm. The bottom bracket shell is 68 mm (road) or 73 mm (MTB) wide. The bearings sit in cups that are pressed into the frame.
PF30A — asymmetric variant of PF30 for road frames, used among others by Cannondale. On the non-drive side the bottom bracket shell is 5 mm wider than with PF30.
OSBB — Specialized Over-Sized Bottom Bracket; a former Specialized standard with a narrow 61 mm bottom bracket shell.
BBright42 — asymmetric press-fit standard by Cervélo with a bottom bracket shell inner diameter of 42 mm. The shell is widened by 11 mm towards the non-drive side relative to the centreline.
BBright46 — asymmetric press-fit standard by Cervélo with a bottom bracket shell inner diameter of 46 mm. The shell is widened by 11 mm towards the non-drive side relative to the centreline.
