The Token Ninja Thread Fit 7 In 1 Bottom Bracket exists to let you fit a variety of different cranksets to your PF30 or BB386-sized frame. It's a robust, creak-free design, and if you have issues with noise or see yourself swapping cranksets regularly, this might be for you.
The Ninja 7 In 1 kit is based around Token's TF37 bottom bracket. The design seeks to solve the eternal problem of creaking by using a proprietary mixture of plastic and fibreglass over the alloy shell that the bearings sit in. So between the bearing/alloy shell and your alloy or carbon BB shell is a layer of composite material designed to fill the gap and not be noisy.
In order to remain in place, the two halves thread together – so it's combining pressed bearings, pressed composite and threads, all designed to work together. Another bonus of having the two halves of the BB in perfect alignment via the threaded centre section is guaranteed perfect bearing alignment left and right – even a tiny aberration in bearing alignment will see one or the other sides fail prematurely due to uneven loading and excessive off-axis force on the individual bearings.
What you get in the 7 In 1 kit are adapters, spacers and washers, wavy and flat, to allow the fitting of four different crankset designs – Shimano Hollowtech II 24 mm, SRAM GPX, BB386 or BB30 – into PF30 or BB386 bottom bracket shells. The only non-starter is putting a BB30 crankset into a BB386 shell – that combo don't hunt, as the BB30 spindle is too short for the BB386 shell width.
Why you'd want to pay an amount extra at RRP for this flexibility is the crux of whether the 7 In 1 kit is for you. Maybe you've invested a fortune in a power measuring crankset, which you want to swap easily between bikes with differing BB standards. Or maybe you are planning to buy a new bike at some stage that you know will be a 46mm-diameter PF30/BB386 shell, which you might want to swap the Token into – I'm sure there are other valid use cases out there.
