Wheels Manufacturing BB 24mm Spindle Shim Spacers (10-Pack)

Got this to space a 73mm MTB crank spindle onto a 68mm gravel bike frame bb shell. Needed the extra 5mm to make it fit with 2.5mm of spacers on each side. So the 10x 0.5mm spacers were just the right amount. 4 stars only bc it's a tad overpriced for basically plastic washers.

These worked exactly as desired. Fit my 24mm dia. spindle perfectly and was able to use just enough of them to close the gap between the crankarm and the bottom bracket.

I have a Felt FR3 with direct mount rear brakes that wouldn't clear my new Stages Ultegra crank power meter, but just two of the .5 mm provided enough space for safe clearance and it's working fine ever since. They fit perfectly and seem well-made. Glad I went with the .5mm so I could add incrementally, I recommend doing the same for similar use cases.

My dual leg Pioneer power meter had very tight clearance on my chain stay for my bike. I put on two 1mm spacers on my Ultegra R8000-series crankset on the left side and clearance improved. Easy to use, appropriately sized.

Does the job.

I used these when installing an (no longer used) Ultegra Stages left crank arm on a XT crankset. The XT spindle is wider so I needed these spacers to take up the extra slack on the spindle. Wheels manufacturing - always there with a solution you didn’t know you needed... until you do!

You would think this is such a common thing but my lbs couldn’t find it so I ended up having to buy it from Amazon. I only needed 2 but had to buy a pack of 10.

The description says aluminum outer. These are plastic. They work but not what I was looking for.
