Re:
I've got a fair bit of xt m739 stuff, all but brakes as recently sold them.
Shifters
Rear mech
Chainset and bb
Hubs
Cassette
I've got rim options and non-shimano chains too (I prefer sram and kcnc with quick links).
I've also got some dia-compe parallel linkage brakes that are very similar to the xt ones, they may even have the model number 739 iirc.
If anything is of interest, let me know. Got plenty of other parts that could get you a full build, aside from forks, nothing around that period, but if you were looking for newer, I may have something.
