About Bottom Brackets
Bicycle bottom brackets connect the cranks to the bike and allow the crank arms to rotate. There are various sizes of bottom bracket shell on the market, so compatibility needs to be checked. The three most common frame bottom bracket shell widths are 68mm (English threaded road and mtb), 70mm (Italian threaded road) and 73mm (British threaded mtb). There are also many axle shapes and styles, from JIS or ISO square tapers through to the round splined axles such as ISIS or Octalink and then there is the new external cup systems which have the axle built into the crank arms. Some frames are now using the new BB30 system which uses bearings pushed directly into the frame and removes the needs for cups to be threaded into the frame.

Personally, in a bb30 frame I would go for BB30 crank set SRAM red & enjoythe full benefits of your frame. You'll have to add a bb30 bearing set to it for around $40.00
I have managed to buy a 2010 Cayo frame and I want to fit a Hollow tech crank which is ok because it screws in but can you tell me whether the BB30 bearings should be fitted because if they are I cannot see how you would do it given the BB is threaded.Did they change the BB after 2010 or is there a crank set you could recommend to solve this problem Thanks
If your Cayo frame is BB30 do that to fit the Hollow tech.
Shimano Hollow tech are in standard frames only at this moment. For BB30 frames use either FSA BB30 cranks or Sram cranks red BB30.
The Shimano cup adaptors -
allow any hollowtech 2 crank to be used with a BB30 system.
