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.

I am fitting this to my specialized secteur elite
I hope this helps.
I've got clearance in the frame as it's a straight through BB shell and the cable runs clear.
What I need to know is if there is enough clearance on the centre of the bottom bracket tube (as in difference between the plastic tube and the thread on the cups) to allow a cable to be routed through the BB shell.
The plastic tube on the FSA BB has little if any clearance this one looke as if it has a lot more?
