Yo, as the title says 'and BB', maybe change that to 'no BB' to keep the wolves happy

anyone buying the cranks can always get this £10 BB right?

best cheapo BB for this is the 105 octalink "5500" one - about £30-35 new, often 10-15 s/h; otherwise ultegra (6500) or dura ace road (7700) both work as long as they are 109 or 109.5 and octalink V1

Didn't someone say road and track were different spline lengths?

pgin tstr

track is 109.5

so these cranks + this chainring = sexy times

it's such a minimal difference i wouldn't worry about getting the track specific one (7710) although if tossing up between that and the 7700 road, the track one is sealed

EDIT: ignore me they are all 109.5 i think

To my eyes, BB-5500* looks like Octalink v2, whereas BB-7710 is v1. I wouldn't put DuraAce track cranks on a 105 BB for that reason. BB-7710 is only about £50 anyway

*recent production, at least. It seems to have been issued in both spline lengths with no model number chainge.

Correct, Dura Ace Octalink cranks only work with DA Octalink BBs, not 105 or Ultegra.

I think mdcc_tester might be onto something in that the 105 design has changed: e.g. this is very confusing (says v1 but clearly v2 spline: http://www.biketiresdirect.com/product/shimano-105-bb-5500-v1-octalink-bottom-bracket) but other than that I think you're ok with the ultegra one which is definitely v1..

Sheldon says:
Octalink ® V1 Spline: 9 speed BB-M952 (XTR), BB-7700 (Dura-Ace), BB-6500 (Ultegra), BB5500 (105)
V1 BB spline grooves 5 mm long, ridges 2.2 mm wide.

That said I run mine on the 7710 track BB, just because the DA road one is unsealed. I assume OP used a 7700 or something else as he said it was italian threaded (7710 is english only because NJS)

I have the correct BB for this I'm pretty sure.

Minimal use (like less than 100 miles, if that) - not sure where one of the cups is though.

Also, do not mount a crank designed for octalink v1 on a v2 spindle, it will knacker the crank.
