Item # SRM0378


Typically unsung, this SRAM GXP Team Bottom Bracket is what you'll find supporting your SRAM road or Truvativ mountain crankset. It's identical to the bottom brackets used in the Force and X0 groups.

SRAM's bottom brackets, while interchangeable between all SRAM and Truvativ cranksets, are brand specific -- meaning, they can only be installed with SRAM cranks. The key element that makes them different from a Shimano or FSA bottom bracket is that the left side bearing has a smaller diameter to mate with the stepped spindle of the SRAM crank. This design allows the inner race of the left side bearing to be captured between the crankarm and the spindle, effectively locating the crank. The right side bearing "floats" on the spindle handling only radial loads as you pedal. The SRAM design optimizes bearing load, minimizes drag, and gives you durability.

The GXP Team Bottom Bracket has alloy cups, anodized in Dark Silver. It's compatible with all SRAM road and Truvativ mountain cranksets. It comes in English threading only and will fit 68mm or 73mm bottom bracket shells (spacers included for 73).

  • Compatible with all SRAM road, Truvativ mountain cranksets

Here's what others have to say...

This says "needs spacers to be used as a 73mm" that is fine but the last one I bought that worked on 68/73mm (not this brand) just used a "spacer"/"washer" type thing on the threads to "shrink" a 73mm for use as a 68mm... I don't want that type of setup.... I just want a 68mm. does this one start out as a 68mm? Thanks

You'll always need a washer or a couple with this BB. I think its one with a 73 and 3 with a 68. The only time you wouldn't use one is with a E-type front derailleur which are rare these days. Refer to instruction manual for exact numbers to use and which side to use them on.

Responded on

If you are using a MTB crankset on a bike with a 68mm shell, you use the included spacers. If you are using a road crankset on a 68mm shell or a MTB crankset on a 72mm shell, you won't need the spacers.

Responded on

Ok, but the included instruction page for a SRAM crankset indicates that the spacers should be used for all but a 72mm shell.

I never much liked the graphic only type instructions and its a bit confusing as I did not think you should use the spacers for a road 68 shell but they seem to indicate otherwise????

It works

  • Familiarity: I've put it through the wringer

Installed it this summer. Logged 3,000 uneventful miles on it. No problems. Seems to do just fine in the rain.

Smooth Character

  • Familiarity: I've put it through the wringer

Only one season on this BB, but thus far it's been running as smooth as a roadie's calves. Pretty inexpensive way to keep the cranks running smooth all season.

3rd season now and it still works great!

  • Familiarity: I've put it through the wringer

I've put almost 10,000 miles on this bottom bracket with my SRAM Red cranks and have not had any problems. 2x a year I will remove the BB, clean it, grease the threads, and put it back together. I don't ride in the rain very often, but I do ride through the winter when the BB is exposed all the sand and other crap.
I'm not sure how often you are supposed to replace a BB, but I can see getting another year out of this one (at least) and if I have to replace it, I know it won't hit my wallet hard at all.

Works good

It lets my cranks spin real smooth like

...keeps on tickin. Dozens of rock strikes later, spins smooth.

Very solid

Not my favorite installation or sealing setup out there, but once its installed it doesn't matter. These take a lot of abuse and keep spinning.

Does what a BB does

  • Familiarity: I've used it several times

I found it kind of hard to track down a SRAM Italian BB and this one does the job great and CHEAP! No creaking or anything like that yet, I'm using for a Force Crank on a Pinarello.

Nice BB

  • Familiarity: I've put it through the wringer

I've used this thing for a full season now, no creaks or squeaks! In a world where you can't buy much for under $100 this is a great component at a great price. definitely planning to give it a nice cleaning this winter and keep rockin it.

Finally Replaced

  • Familiarity: I've used it several times

Finally got around to replacing my hand-me-down GXP with who knows how many miles on it, but still ran like champ. Only issue was that it made some clicking noise from time to time. But with new cranks I figured I should get a new BB and now it's super smooth and silent

Smooth and Light

  • Familiarity: I've put it through the wringer

This is a great bb that's super affordable. If you aren't bound by having the most expensive parts on your bike there really isn't that any weight difference between this and the blackbox xx version. Your biggest difference is your bearings, but I have this on three of my bikes and my spouses and they are bullet proof. Never had any issues or complaints. I like the darker anodized look too.

Smooth spinning

This is my second GXP BB and it fits and spins smooth with my SRAM X9 cranks. I rode my first one the better part of a year and it still has plenty of life in it, I bought a new one to take on the great divide and I will surely put it to the test.
