Subject: [CR]Interchangeability of Dura Ace BB's

To what extent can newer Dura Ace BB's like 7400 and maybe slightly newer ones be used with On Topic Dura Ace cranks like original DA and DA AX and EX? I find I have accumulated a lot of DA 7400 cranks which came on KOF frames or retrofitted on On Topic frames. This stuff works well and doesn't look bad, but I usually replace it with something more On Topic, although I must confess I retained the 7400 gruppo on a 1988 Mercian KOM, and it works very well. I've been buying some original and AX/EX DA cranks lately, and wonder if I can reuse the 7400 BB's with these.

BTW, if anyone wants a real good deal on DA 7400 stuff, contact me offlist.
