How can you tell the difference between BB30 and GXP?
Main Differences Between GXP and BB30
The bearing of a GXP has a ceramic seal while on the other hand, the bearing of a BB30 has a silicone seal. The measurements of a GXP are 5.1 by 3.4 by 2.2 inches, whereas on the other hand, the measurements of BB30 are 4.5 by 2.3 by 2.3 inches.
Is BB92 the same as PF92?
The frame’s bottom bracket shell inner diameter is 37mm. A bearing with an OD of 37mm is pressed directly into the frame. Trek is moving away from the BB90/95 system to what they call PF92, which is the same as a BB92 (41mm ID shell and 92mm width).
Do I have BB30 or GXP?
If your cranks are already removed, the easiest way to tell what you have is by measuring at the spindle diameter. As the name suggests, a BB30 or PF30 crank will have a 30mm spindle diameter, while a GXP crank’s spindle will measure 24mm with a 22mm splined portion on the end.
What does SRAM DUB stand for?
Durable Unified Bottom Bracket
In 2018, SRAM introduced mountain bike cranksets which use a new technology name DUB™ (Durable Unified Bottom Bracket). Meant to simplify frame BB and crankset compatibility across their product lines, it brought about yet another standard to understand.
What is the point of SRAM DUB?
DUB shrinks the diameter of the axle just enough to allow for proper sealing with all bottom bracket configurations. A casual glance will find the new DUB axle size barely discernable from BB30. Closer measurements show it actually has a diameter of 28.99mm. That 1.01mm makes all the difference.
Can I use Shimano bottom bracket for SRAM GXP crank?

Can I use Shimano bottom bracket with SRAM?
SRAM DUB bottom brackets aren’t compatible with Shimano cranks either. DUB bottom brackets are designed for a 28.9mm spindle. And since Shimano cranks rely on a 24mm spindle, a combination of the two results in a non-secure fit.
Does bottom bracket spindle length matter?
The critical thing is your spindle length: as long as you can set up the correct chainline you will be good to go. But, again, best never to mix standards if you can at all avoid it. If you are looking to replace a cottered crank setup with a square taper setup, then look no further than a cartridge bottom bracket.
Is BB90 and BB92 the same?
They are one and the same bottom bracket. 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.
How long do bottom brackets last?
As for a bottom bracket, on the low end, maybe 5000 miles. The basic Shimano one most people use (UN51/55/similar) can reasonably expect 10k+ miles. But sometimes you get unlucky and get a bottom bracket that lasts maybe 500 miles.

Can I use a Shimano crankset with SRAM?
Thus, cranks from Shimano, SRAM, and Campagnolo are freely interchangeable along with those from all aftermarket brands (e.g. FSA, Rotor, Praxis, etc.). And while it is preferable to match the chainrings/crankset to the transmission, there is no strict need to do so.
What spindle length do I need?
The best way to find out which spindle length you need is by looking up the specs. (The alternative is trial and error…) Spindle length and the resulting chainline have some leeway. If you are within 2-3 mm of the “correct” 43.5 mm or 45 mm, you are doing quite well.
