    Unsung hero.

    The SRAM GXP Team Bottom Bracket features Gutter Seal Technology to reduce friction and weight for smooth-spinning performance. Brand specific, this bottom bracket can only be installed with SRAM and Truvativ cranksets, due to its left side bearing, which uses a smaller diameter to fit with the stepped spindle of SRAM's cranks. Note that this bottom bracket is compatible with all SRAM road and Truvativ mountain cranksets, and it comes with English threading only. It fits 68 and 73mm bottom bracket shells, with included spacers for fitment with 73mm bottom bracket shells.

    • Compatible with all SRAM road, Truvativ mountain cranksets
    • Fits 68, 73mm bottom bracket shells (comes with spacers for 73mm)
    • English threading

    Affordable, durable

    • Familiarity: I've put it through the wringer

    The Team GXP bottom bracket with steel bearings is a good value. Installation is a cinch and so far the BB has held up well. I had it on my last bike for well over a year and the bearings were still spinning freely when I sold the bike. This is for 68 or 73mm BSA shells and SRAM GXP cranksets.

    Works as expected.

    • Familiarity: I've used it several times

    Great tool for the job. When your old GXP bb wears out, pick this up and you will love how smooth your pedaling becomes. At this great price point it is definitely worth getting a new BB for your bike. Do it!

    Smooth, quiet, like a new bike!

    My husband and I both got this bottom bracket as part of the whole SRAM Red eTap Road GXP Groupset. This review is for the entire group.

    Hubby says: I purchased two SRAM Etap groups to upgrade both my wife’s and my road bikes. Both bikes had relatively old drivetrains (hers 10+ year old Ultegra and me 15 year old Campy Record) so we figured it was definitely time for an upgrade and because our bikes have S&S couplers the wireless aspect of Etap made a lot of sense for breaking down the bikes for travel.

    Installation: Etap was far easier to install than any other build I have done. After removing all the old parts and degreasing the frame and giving it a good scrub, I had everything installed in about an hour and a half, the most time consuming part being the brakes. SRAM has some excellent YouTube videos explaining how to install the parts and after viewing them a couple times, it was pretty straightforward. One thing to watch out for is the braze-on adapter. We have titanium bikes which require this adapter and I tried using the Shimano one that was on my wife’s bike from her previous group. With this adapter, adjusting the front derailleur was impossible, but once I switched to the SRAM adapter everything worked normally. I know, it’s probably obvious but I just figured there was some cross compatibility between SRAM and Shimano but it appears that’s not the case. Minus points for the braze-on adapter being a separate component that we needed to buy to complete the install.

    Adjustment: this part was surprisingly easy, especially compared to mechanical groups I have worked with in the past. SRAM’s video instruction was clear and concise and the front derailleur has little marks on it showing where it needed to be mounted in reference to the large chainring. The rear derailleur was equally easy as well, just use the micro-adjustment buttons on the shifters to line it up with the large and small cogs of the cassette respectively. Once that was done, I fine tuned the adjustment by putting the bike on the trainer and riding it, adjusting as needed with the micro-adjustment buttons on the shifters while shifting into every gear.

    Riding: The first ride felt like I had a brand new bike. The difference between this and my old group (granted it was pretty old) was a revelation. The first week or so of riding I was getting Strava PRs all over the place and at my age, I ain’t getting any faster so it definitely has to be the drivetrain. The new method of shifting (left shifter easier gear, right harder, both change front chainring) took a little getting used to but now that I have, I love it. Shifts are quick and concise with no delays, clicking or grinding, even under heavy pedaling load. The brakes are also nice, with good modulation and stopping power, even on carbon rims. One final point about this setup is it’s seriously quiet - almost zero noise out of this drivetrain which is one of my favorite features.

    I was a bit nervous about dropping so much money on electric shifting but once I had it on the bike those nerves disappeared. The components are high quality (as is the packaging - it seems SRAM has taken a page out of Apple’s book), the installation is really easy and the performance of the group is outstanding. I highly recommend this setup for anyone wanting to upgrade their bike.

    Works Fine

    Bottom brackets are a "wear and tear" item; you'll need to replace them more frequently the more you ride (and even more frequently if you ride in wet/gritty/muddy/salty/humid conditions) and this is the proper choice for a GXP spindle and 68/73mm threaded frame.

    Gets the job done

    • Familiarity: I've put it through the wringer

    This SRAM BB will get the job done, it's reliable and will hold up for quite some time. If you are looking for a more efficient BB, consider a Steel Chris King or a Ceramic BB.

    Solid, good price point

    • Familiarity: I've put it through the wringer

    I like the SRAM GXP system. Simple to install and remove the BB and Crankset. The team gxp bb is at a good price point. I don't like spending a bunch of money on the BB since they wear out like chains and tires. Only annoying thing is that the dust cap seems to pop off easily when the crank is not installed but it's a non issue once the crank is installed.

    Last and lasts

    • Familiarity: I've put it through the wringer

    I have only 10k miles on this BB and it's still going strong. I don't ride at all in the rain or mud though. Mainly typical CA weather. Solid BB and never needed any servicing.

    Pressfit like BB30 or BB86? I didn't notice any issue with this but I guess I'm on the lighter side.


      Never an issue with these threaded BBs. Reliable and last for a long time if you take care of your bike. I'm in UT so it's pretty dry here, if you're in a wetter environment they might not last as long.

      Works like a bottom bracket

      • Familiarity: I've used it several times

      seems like it will be a fine bottom bracket. Obviously if you have the money go Chris king or even sram ceramic. But if youre like me then this will do just fine.

      Shouldn't have to sell you

      • Familiarity: I've used it several times

      SRAM makes great stuff. Shouldn't have to sell you on this bottom bracket. Incredible value and super smooth pedaling.

      If you are considering buying this, buy it.

      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.

      Unanswered Question

      Hi There,
      I have a SRAM gxp chainset, it came with an English bottom bracket. My bike has an Italian bottom bracket shell (70mm wide, rather than the English 68mm). Will the axle length be OK, if I buy an Italian threaded gxp bottom bracket? Do sram make the cups 2mm narrower, so that the distance between the cranks is still the same, or do I have to buy Italian specific cranks?
      Thank you.

      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.

      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.

      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????
