    Push it real good.

    The SRAM PressFit 30 bottom bracket is designed for frames that use the—you guessed it—PressFit 30 bottom bracket standard. If your bottom bracket shell has a 46mm ID, this is the bottom bracket you need. It'll work with any BB30 crank. The unit comes complete and ready to install.

    • A bottom bracket for PF30 BB shells and cranksets
    • Durable steel bearings remain the industry standard
    • Compatible with BB shells from 68 to 92mm wide, including BBright and BB386EVO
    • Item #SRM0317

    Works perfectly if installed correctly

    • Familiarity: I've put it through the wringer

    Inexpensive, high quality and light.
    You do see a lot of online comments slagging this technology as being noisy, creaking, etc. Well, not if you install it correctly.
    Most of these negative reviews are in support of spending $150+ for some heavy, machined aluminum, ceramic bearing waste of money. What I mean specifically, is that no grease is called for during the install. The confluence of two unfortunate realities get in the way of proper install. One, that most "professional" bike mechanics automatically smear hand fulls of grease all over every bike component -especially bottom brackets- during install, and the other that few people bother to read instructions. If one does read the printed instructions included in the box, there is no grease called for for PF30. On SRAM instructions, areas calling for grease are highlighted in blue. A small amount of grease goes on the o-ring in the tube, but none on the seating surfaces. In fact, grease ruins the friction fit aspect of PF30. Show me someone with a creaking unstable PF30, I'll show you someone who smeared it with grease or otherwise screwed it up.
    My PF30 (BH G5 frameset/ Force crankset) is going on 5 years old and many thousands of hilly miles, and it still works as new. You do see the suggestion to add loctite to the seating surface, but I did not. Also, install it once and leave it there. Repeated removal and re-install will wear it out and make it loose. Only remove it when you're going to replace it with a new one.

    This is a BB

    • Familiarity: I've put it through the wringer

    It comes with bearings and a shell. Dunno what else to say. It works. Replace them every 6 months if you ride a lot, 8 months if you ride a fair amount, every year if you don't ride as much as you should.

    Super simple

    • Familiarity: I've used it several times

    I would say "super duper simple" but that would require that this never existed and every bike had a threaded bottom bracket shell that works fine. But, that is not the case anymore. I recently installed this on my Yeti ASRc and it was super simple. Just grease it and press it in. I then used a PF30-to-GXP adaptor and used my existing SRAM GXP XX1 crankset, 168 q-factor. It just works.

    Good PF BB-30

    • Familiarity: I've put it through the wringer

    It does the job on my BH cross bike. It fit in nicely and is smooth. The BB-30 seems to spin more freely than a 24mm bottom bracket. It has held up through snow, salt, ice, and mud. I clean it up from time to time and I am good to go. I doubt it is worth moving to ceramic, especially since you can afford to replace it more often since it is only $40.
