Keep the pedals turning.

The Wheels Mfg PF30 to Shimano Bottom Bracket with ABEC-3 Bearings lets you install your favorite 24mm crankset into that new PF30 frame. Made with Enduro ABEC-3 bearings, high carbon chromium alloy races, and machined aluminum cups, this bottom bracket will keep the cranks turning smoothly mile after mile. A dual silicone seal blocks out particles for a longer overall life.

The Wheels Mfg PF30 to Shimano Bottom Bracket with ABEC-3 Bearings is compatible with 24mm spindle cranksets such as Shimano and FSA without any adapters needed. It features an easy-to-install threaded design that addresses the creaking and bearing alignment issues we've all come to associate with PressFit bottom brackets.

  • A handy bottom bracket to transcend standards
  • Converts PF30 to 24mm spindle with ease
  • Removes the need for finicky adapter cups
  • Threads together to reduce creaking, improve bearing alignment
  • CNC machined aluminum cups are durable and precise

Is this BB good for a Niner Sir 9 (PF30) and XT M8100 cranks (24mm spindle)?


easy install, no creaks

  • Familiarity: I've put it through the wringer

I once had a bike with a creaky pressfit bottom bracket and vowed to never do that again. This bottom bracket is the antidote. It's easy to install, the threads ensure a precise fit, and I've yet to have any issues. No-brainer choice here.

Easy and no creaks

    This is a nice one piece bb and conversion that allows you to run shimano cranks on a PF30 bb shell. Instead of having a bb and an adapter, this covers all of it in one unit. Super easy to install and so far I've had no creaks at all.

    Perfect fit

    I couldn't wait to install this BB...Wheels Mfg. makes really quality stuff across the board...easy install, secure (meaning no adjustment needed)....STOKED.

    The way to go

    • Familiarity: I've used it several times

    I am using this on my Ridley Helium SL PF30 and it works great. Installation is easy with the right tools. I recommend you watch the videos on the manufacture's web site before installing. The quality is high and the threads make all the difference. So far no noise (the biggest issue with PF in my opinion). I have not had the chance to put it through the wringer yet, but I have ridden on the trainer multiple times.

    Great solution conversion

    Awesome BB for the money. Used this on my Ridley Helium XLS to run a Shimano crankset on the PF30 shell. Works great, and is priced really well for the quality.


    • Familiarity: I've put it through the wringer

    I used the Wheels Mfg. conversion on an Air 9 RDO build along with XT cranks. I found this to be a more desireable solution to threaded inserts of other adapters.

    Great product

    • Familiarity: I've used it several times

    I purchased this BB for my Santa Cruz Stigmata. The price is very reasonable and it looked like a great option to accept my Shimano cranks. The amazing team at CC installed the BB before shipping the frame out. So far I have about 600 miles on it with mixed dirt and road. I could not be happier with the product and it is still buttery smooth.
