A Hambini BB user sent in this video of his Specialized Tarmac SL6 with a Hambini Racing BB30 to Shimano Bottom Bracket installed. As always, an unloaded spin test is not a good indicator of loaded performance!

  1. I run the same combination. Same result. Smooth as f***
    No reference to my canyon before which had obviously a undersized ovalized NDS hole. even the Hambini BB86 Unit didnt get away with it without a problem. The fact that the bearings sit outwards in this case of a BB30 with a Shimano type crank is a advantage in my opinion. Definitly better than there obviously misaligned BSA SL7 Design where you are f**** if you need to Fix the alignment. Pressfit is King
    Sold the ceramicspeed bearings that did come with the frameset for almost nothing… better than nothing.

  2. Hi great video I must say.I’m not an expert but is that Specialized SL6 threaded bottom bracket?if so I I’ve got the same bike but my spin test look rubbish ( Only 3 turns!) I love to upgrade please.What should I order, thanks for your reply.

    1. You’d need a BB30 to Shimano (if you have a shimano crank)

      1. I have a S Works Tarmac SL5 with Shimano Ultegra cranks, which bb do i use ?

  3. Mine is currently on order! I managed to source a fantastic deal on an S-Works SL6 frameset in my size at a LBS. They’d tried to sell the complete bike in a SRAM Red eTap AXS build but no one was buying. They eventually found a buyer for the groupset alone, and I was happy to take the new old stock frameset off their hands. This BB will hopefully be the centerpiece of a fantastic build!
