Description

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).

Great product

  • Familiarity: I've used it several times

Flawless bottom bracket. No complaints, lightweight, and still heavy duty for my gravel bike.

High quality bargain BB

  • Familiarity: I've used it several times

Just updated my bike with a 1X11 GX drivetrain. This is the bottom bracket I went with. Great price and outstanding quality. Highly recommend.

Cheap and Great BB

  • Familiarity: I've put it through the wringer

This has been a great buy for me so far. Easy install and looks great. It is very smooth and quiet. Can't beat the price and quality.

Smooth as butter

  • Familiarity: I've used it several times

Figured as I was upgrading to the Eagle GX why not change out the bottom bracket as well, make life easy with the installation and compatibility. Great bb so far, spins great, feels solid and super happy with the entire upgrade.

Easy Install, Spins Smooth

  • Familiarity: I've put it through the wringer

Great BB, no issues to note. Spins smooth with no creaking or other problems.

Function!

  • Familiarity: I've put it through the wringer

Works well on my 2018 Evil Wreckoning with my Descendant Cranks. Note - this only works with GXP specific crankarms. So keep that in mind.

Solid performance

  • Familiarity: I've put it through the wringer

The perfect option for GXP cranksets, this bottom bracket will keep things running smoothly for miles to come.


cheap, easy, last a long time

    Great BB for sure, cheap, easy to install, lasts years this is my 3rd on my frame I change it around once every 1.5 years, great product! Threaded BBs are just the best.

    Quiet!

    • Familiarity: I've put it through the wringer

    Super easy to install and no far no creaking sound! I have about 100 miles on it and doesn't seem to be stopping anytime soon. No reason to feel like to should have waited for the new DUB technology since this one is tried and true.

    right price, good performance

    • Familiarity: I've used it several times

    Bought this for a GX eagle upgrade. Easy install, spins right after the first couple rides. Can't speak to long-term durability but modern sealed bottom brackets seem nearly bombproof. I tend to move onto a new bike before I wear out a bottom bracket (creaky press fit the odd exception). Comes with spacers but no install instructions. I suspect the spacers take it from a 68mm bottom bracket shell to the mtb 73.

    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.

    Spins real good.

    • Familiarity: I've put it through the wringer

    Compatible with Hightower LT and SRAM Descendant Carbon 12-Speed GXP Direct Mount Crankset.

    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.

    Smooth like butter

    • Familiarity: I've put it through the wringer

    Smooth and quiet operation, no creaks, spins like new even after a wet muddy winter!

    Works Fine

    • Familiarity: I've put it through the wringer

    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.
