Original kit on the was M730 with the 'endless band' on front mech, a bit tricky to find. Also the rear brake operated via a rocker which is also manufactured in unobtainium if you havent got one.
The headtube is 1 1/4 and was specced with the combined titanium flexstem and bar combo.
Mine pre Pickle with M730 nicked for my GT and replaced with DX/ Deore MT-60 mix
the rear suspension can be easily repaired using those big fat elastomers found from underneath those big fat ladies seats (the seats, not the ladies)
Its a long term build so will try and spec all M730 and I think the rear brake rocker is present, good advice on the Elastomers as I was a little worried about sourcing these
just need to find a Flexstem bar combo then. Again everyone thanks for your kind words and advice
