Will SRAM work with PF30 bottom bracket?

Standard

Will SRAM work with PF30 bottom bracket?

SRAM makes their PF30 Bottom Bracket Assembly to fit frames that use this pressfit standard. If your bottom bracket shell has a 46mm ID, then this is the bearing set that you’ll need to install your BB30 crankset. Be aware that it will work with any brand of BB30 crank as well.

What’s the difference between BB30 and PF30?

A PF30 frame has a shell slightly larger than BB30 (46mm compared to 42mm). The bearings are pressed into cups which are then pressed into the frame. In the case of the PF30 systems the bearing cups rely on flanges to ensure that both cups are pressed the proper depth into the frame.

Is SRAM dub compatible with PF30?

PF30 Outboard ABEC-3 BB for 29mm SRAM DUB Compatible Cranks – Black. PF30 with outboard bearing BB for use with 29mm spindle SRAM DUB compatible cranksets. The two machined aluminum cups thread together keeping the bottom bracket stable in the frame, increasing bearing life, and simplifying maintenance.

What bottom bracket does SRAM use?

Durable Unified Bottom Bracket
In 2018, SRAM introduced mountain bike cranksets which use a new technology name DUB™ (Durable Unified Bottom Bracket).

What size is a PF30 bottom bracket?

The PF30 bottom bracket shell is typically 68mm (road) or 73mm (mtb) wide with an inside diameter of 46mm. The bearings are pressed into cups and the cups then pressed into the frame.

Is GXP compatible with PF30?

The designers at Wheels Manufacturing agree, and their BB30/PF30 to SRAM GXP Bottom Bracket Adapter aims to do just that. This adapter isn’t picky — it’s compatible with almost any BB30 or PF30 frame with a SRAM/Truvativ crankset, including mountain or road bikes.

Can you convert PF30 to BB30?

Yes. Same standard, different installation into frame though. Absolutly right. Though you can’t run a BB30 bottom bracket in a PF30 frame, or the other way around.

Are BB30 and PF30 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.

Is BB30 and dub the same?

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.

What cranks are compatible with SRAM DUB bottom bracket?

As such, below is a list of bottom bracket standards that SRAM’s DUB cranks will be compatible:

  • BSA 68 (threaded)
  • BSA 73 (threaded)
  • BSA 100 (threaded)
  • PF89.
  • PF92.
  • PF121.
  • BB30 73.
  • PF30 73.

Are SRAM DUB bottom brackets good?

DUB bottom brackets are really good, especially the threaded, outboard-style one. SRAM re-engineered the sealing system in order to fix the water ingress problem that had plagued earlier designs, and by reducing the size of the spindle, were able to make a reliable solution for the BB92 standard as well.

Are all PF30 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. This is the bearing category designation.
