    BB30 conversion made easy.

    Providing added stiffness and weight savings, the BB30 system is offered on a small, but increasing number of race-worthy road frames. The problem lies in compatibility with Shimano's popular cranks, such as Ultegra and Dura-Ace. That's where the Wheels Mfg BB30 Adapter For Shimano comes into play. This nifty solution fits Shimano road cranks to BB30-equipped frames, thanks to its two reducer sleeves that precisely press into the BB30's bearings for wiggle and creak-free performance. Please note that this adapter works with all Shimano and Shimano-compatible road cranks with a 24-millimeter spindle.

    Easy, fast, and cheap

    • Familiarity: I've used it several times

    This is definitely the easiest and fastest way to convert a 30mm bottom bracket to use a Shimano crankset. Adapters just press in and the kit comes with plenty of spacers to get the ideal chain-line.

      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.

      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.

      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.

      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?

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

      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?

      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.
