Bought a fancy new road frame that needs a BB30 bottom bracket? Already have a Shimano chainset? Then you need this ingenious solution!
  • This adapter is a very simple solution to a potentially expensive problem.
  • BB30 frames are becoming more common but quite often riders want to fit a Shimano chainset.
  • This easy to fit adapter will allow you to run your Shimano chainset on your BB30 frame.
  • It includes all fittings, spacers and even comes with sealed cartridge bearings.
  • No additional bottom bracket is required.
Rupert Well made adapter rings with bearings ready fitted. Fitted myself using bearing press making a simple job of converting a FSA BB30 crankset to Shimano Untegra in less than a half hour. Cannot comment on the quality of the bearing set till the bike has been ridden for a good mileage but all seems snug and smooth now.
mark Worked great, very easy, new cranks fitted within minutes. Great service as always from Merlin cycles
Fi This would appear to be a reasonably priced bit of kit for fitting a Shimano hollowtech crankset into a BB30 frame. Just done my first ride and all seems good - no creaks etc. Only time will tell, but seems a good product.
Mr Damgaard Super adapter that will make your BB30 crank ready for use with Shimano components. Easy to install.
Abu Jose A very useful kit for BB30 frameset.
Mr Miller Great quality low cost option to fit my Ultegra crank to my De Rosa BB30 frame. Fit perfectly with no fiddling and no creaks or noises from the bottom bracket.
Mr Manabat I had this installed on a BB30 road frame to take an Ultegra crankset, so far no issues. Sealed BB30 bearings that came with the adapter (looks to be aluminum) was more cost effective than buying both separately from Wheels Mfg. Will have to see if RSP (Taiwan made), will last long and perform as advertised.
Mr Grimmer A solid bearing set but no dirt/moisture barrier for the BB. Just the same, installed well and works great with the Dura-Ace chainset.
Mr O'Connell This adapter worked perfect to convert my Boardman Team Carbon to accept a Shimano chainset.
Mr L Great BB30 adapter for Shimano Ultegra.
Mick Le' Ginge' Straight forward to fit (need a press fit tool, or courage with a vice, mallet & wooden blocks). Bearings run smooth and silent. Matched this with an Ultegra 6750 compact and they compliment each other well. A good solution to non BB30 chainsets.
Mr Osman Great product at a good price. Neatly converts BB 30 bottom bracket to accept any shimano crankset. Easy to install. A much cheaper solution than buying a new crankset. No special tools required, I carefully tapped bearings into the frame using a block of wood and a hammer. Took about ten minutes to install. Excellent job.
