Are BB30 and PF30 the same?
Are BB30 and PF30 the same?
ARE PF30 & BB30 the SAME? No they are not the same. But they are also not all that different. 6806 is a number you’ll see describing the bearings used for both pf30 and BB30.
What is the difference between BB30 and BSA?
While both standard BSA threaded frames and BB30 frames have 68mm shells for road bikes, the external bearings of the BSA frame when used with an outboard bottom bracket would render a standard BB30 crankset’s spindle too short to use with a BSA30 bottom bracket.
Is SRAM dub BB30 compatible?
DUB is compatible with BSA threaded, PF86, PF92, BB30 (73mm shell) and PF30 (73mm shell) bottom brackets and cranksets are completely interchangeable between the different standards.
How can you tell the difference between BB30 and GXP?
The difference between GXP and BB30 is that the full form of GXP is Giga X Pipe. on the other hand, the full form of BB30 is Bottom Bracket. The GXP measures 5.1 by 3.4 by 2.2 inches and its weight is 145g. On the other hand, the BB30 measures 4.5 by 2.3 by 2.3 inches and its weight is 153g.
Is SRAM dub 30mm spindle?
Previously, SRAM had two different spindle diameters (30mm and 24mm), along with a range of bottom bracket bearing sizes. With DUB, they now offer one spindle diameter and four bottom brackets that will fit all of the existing frame standards.
What is the difference between a BB86 and a BB92?
Well, BB86 refers to road bikes with their 68mm BB shell; BB92 refers to mountain bikes with their 73mm BB shells. BB90 is Trek’s proprietary standard and is the odd one out here. Like BB30, the bearings sit directly in the bottom bracket shell.
What size BB do I need for SRAM frame spindles?
SRAM and some other manufacturers make spindles that are 24 mm wide at one end, and 22 mm wide on the other, so the correct matching BB needs to be acquired. If the frame has a press-fit BB shell (without threads, threadless), then you need quite expensive, special tools to install and remove/change BBs.
Should you upgrade to a BB92 bottom bracket?
If you are thinking of upgrading from your current mountain bike with its 73mm bottom bracket shell/external bearing setup, you’re in luck. This is a good move, by the way. The idea behind the BB92 standard is creating a beefier frame around a 24mm standard drive train.
What is the difference between Trek BB30 and BB90 bearings?
BB90 is Trek’s proprietary standard and is the odd one out here. Like BB30, the bearings sit directly in the bottom bracket shell. Neither BB90 nor BB30 is as widely used as the others. BB90 is obviously brand specific. BB30’s issues has seen it long since overtaken by PF30.
