The very original spec was full xt including cranks, hubs and STI shifters (except diacompe 986 canti, and a dura ace headset), it also used rock shox RS1 forks, XT bear-trap pedals with zefal clips and straps, white onzas and pink odi attack grips, mavic 261 rims, 3ttt salsa bars and a salsa pro moto stem with roller (?!). That was the original Team Salsa/A'me spec when Jason was first sponsored to ride Salsa, a year before he rode the salsa for MBUK. That was the spec featured in the 1991 article 'young Turks'.
That said, it doesn't detract from the fact that the MBUK ones are not Cooks or CQP cranks, but are almost certainly graftons as per the sponsors of the team.
