[Closed] Ideas for a P7 Refurb please -

As you might know from another thread, my poor old Orange p7 was recovered this week. Prior to it's disappearance, it had sustained some light damage - the chainrings and chain had got caught up and were damaged. the left shifter didn't always shift either.

Its a 1-1/8 headseat and does have a disc tab on the rear, Think the frame is from from about 99/00, and I bought new in 2001. Basically, I don't need mega travel on the front, and I like the "old fashioned" geometry ie a longer top tube, lower head tube and seat further over the rear wheel than a more modern frame.

So I'm thinking, as I had it from new, time to "treat it" after its recovery. So help needed please on ideas?

My thought was - treat it to some decent spaced down forks, of say 80mm max (presently on there is an elderly Rockshox Judy XC Airs), but I don't really know whats out there in the shorter fork length. Googling suggests you can get xc30's in that length. Or are there better options? Then getting in a shorter stem and some riser bars.

The BB on the bike is a square taper Shimano. I need a new crank and rings as the old item, an Stx-rc apparently has non standard rings, not interchangable according to my lbs. Will a newer BB standard still fit the frame? Octolink? or these new external bearing things? Or would I be better hunting down some old stock square taper cranks, say LX Deore? Or even some retro items like Middleburns and keeping the BB?

Then thinking some light xc wheels and some disc brakes. If so, whats the way to go? 2x10? Presently running 3x9.

To get it running the crank/rings and chain are urgent purchases. Forks and wheels/brakes can wait.
