We've made no secrets about our affinity for BB30. It's a good bottom bracket system -- it offers numerous advantages over the current external bearing bottom bracket and seemingly no disadvantages except that it is available on a limited (but growing) number of Pro level racing frames. For the Shimano Dura-Ace rider, BB30 has presented a compatibility problem. Leave it to Wheels Manufacturing to come up with a nicely executed solution. Their BB30 Adapter for Shimano cranks makes the fitment of Shimano road cranks to BB30 frames a simple affair.

The Wheels Manufacturing BB30 Adapter consists of two reducer sleeves turned down from solid blocks of Delrin. These adapters utilize a press fit into the BB30 bearings and, once in place, allow you to slide the Shimano crank spindle through just as you would in a standard Shimano bottom bracket assembly. The Delrin supports the spindle perfectly and the resulting performance is exactly what you'd expect from your Shimano cranks -- no wiggles and no creaks.

The Wheels Manufacturing BB30 Adapter for Shimano is compatible with all Shimano and Shimano compatible road cranks designed for external bearing cups and having a 24mm spindle.

These adapters are easy to install and they get the job done. I installed a Shimano Dura Ace FC-9000 crankset (hollowtech II) into my specialized tarmac which has OSBB (which is essentially the same as PF30/BB30). My frame required one of the thicker spacers in order for the 39t chainring to clear the rear chainstay.
Was great for a couple rides, but then there was creaking. I talked to my Specialized guy and it turns out they make a part just for this sort of thing, and it is made of aluminum. WAY BETTER. super easy to install (tip: put them in the freezer first so they slide in easy to your bearings) and they fit perfectly without spacers and having ridden a few times there are no squeeks, AND they were cheaper.

I have a bb68 English thread frame but purchased a bb30 SRAM red crank. Will this product make the two compatible?

Unfortunately, you can not adapt a threaded frame to work with a press fit system. The bearings for a BB30 are larger than the frame you have. You will need the SRAM GXP style to work. Feel free to reach out to me at extension 4769 if you have any questions about compatibility

Works perfectly. Easy to fit.

Upgraded the groupset on my Cannondale Supersix to Ultegra 6800. 5 months and 3000 km later it's still perfect - no lateral movement and no creaks.

Unanswered Question

I Have a new Cervelo P2 11 SPD and I bought an Ultegra 6800 crankset and a SM-BBR60 Bottom Bracket to upgrade the group (the bike comes with a FSA PF-30 Botton Bracket and a FSA Gossamer BBright™ 52/36 crankset). Can I use this adapter to fit the Ultegra group?

Well made

Put together a BB30 frame and used a Shimano Ultegra crank - Standard press fit BB30 bearings were installed as recommended, then these two parts just fit perfectly into the bearings. I was amazed that these work so well, and even when cranking out some torque; no creaks, squeaks, or looseness. Great product.

I'm not totally familiar with all the standards, are SRAM/GXP cranks (which also have 24mm spindles) compatible with this adapter? Right now my frame has an adapter for threaded 68mm shells (to then add a standard GXP BB to it), but it seems unnecessary if this will work with my SRAM Red GXP crankset and BB30 bottom bracket.

Should work on a BB30 frame - it's a super easy install.
