Item # WHL0004


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.

Best solution

    I wanted to replace the FSA SL-K 11sp crank (590g) on my Cannondale with the Ultegra Hollowtech II (620g) because I thought it would be cheaper than buying new chainrings for the FSA. It isn't, if you really hunt for a good deal (oh well). The spacers fit the BB30 perfectly, but they were too wide. I didn't expect this because they talk about the possible need for spacers @ Too wide meant that the left crank didn't fully engage with the spindle so I took 2mm of the drive side and 5mm off the left side. The spacers are made out of Delron so it wasn't that difficult (took me about an hour with a hand scroll saw, rasp and wet sand paper). Not exactly what you want to do with a brand new product, I know. But I got a perfectly centered crank. The Ultegra's and spacers look great, the left crank is fully engaged, and the ride after 100 miles is perfect.

    I left the bearing dust covers off because the spacers do a nice job and I would have had to make them even thinner had I left them on.

    Perfect fit

      Converted a Felt with BB30 to fit a Shimano Ultegra crank. Fit perfectly. No wiggle, no need for spacers. Perfect.

      Unanswered Question

      Hi Guys, just making my listing for the ideal Triathlon bike. I'm planning on getting a 2015 BMC Timemachine TM01 frameset. It says that BB must be a 30. Will it work if I buy a Ultegra 6800 BBR60 and place this adapters?

      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.

      my LBS sold it for $25. well worth it.

      I currently have BB30, thinking to upgrade my Praxis Works crankset onto Shimano Ultegra FC-6800 Crankset.

      Would this fit into BB30?

      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.

      • Familiarity: I've put it through the wringer

      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

      • Familiarity: I've put it through the wringer

      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...

      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.
