    Simply adaptable.

    In the ever-expanding world of bottom brackets, we all just want to keep things as simple as possible. 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. Wheels Manufacturing uses engineering-grade Delrin resin plastic on the adapter, which is both lighter and quieter than aluminum — something we can all appreciate. This adapter is simple enough to install on your own or with a trusted mechanic, as long as you’re working with a bottom bracket shell measuring between 68 and 83mm wide. Once installed, use the two adapter shims as well as the included wide assortment of left and right spacers to ensure you won’t have any play in the crank.

    Sloppy Fit

    • Familiarity: I've used it several times

    This is for the Universal BB30 to SRAM/GXP crank adapters. The 24mm (drive side) adapter worked just right. The 22mm (non-drive side) adapter was undersized to the point you had to use a rubber mallet to punch the drive side crank arm out when performing routine maintenance . You really had to waylay into the spindle with the rubber mallet. Which is fine if you have a regular crank, but I can't see it being a good thing if you're crank is a Quarq power meter. I emailed Wheels Mfg about it and never received a response. I finally ended up sanding the inner diameter of the 22mm adapter to fit correctly. I gave them 3 stars because I also have the Universal PF30 to Shimano adapters on another bike that worked as intended.

    Cheap and easy

    • Familiarity: I've used it once or twice and have initial impressions

    Used this kit to fit a 2008 Sram Red crankset to a 2016 CAAD12 BB30a frameset. Took a couple attempts with different spacers to nail the chain line, but 20min and it was good to go. For under $30 this was perfect for a no nonsense race build.

    Good adapter option for the money

    • Familiarity: I've put it through the wringer

    Less expensive then a complete conversion BB option. This works very well for it's intended purpose and is a very low cost, well made adapter option that just works.

    Simple and very helpful

    • Familiarity: I've used it several times

    Great that they make a product that saves us from having to drop another $400 on a new set of cranks just because we use a different Bottom Bracket! These are really east to install and run smoothly.
